What is HIPAA For Explanation of Benefits Statements?

HIPAA For Explanation of Benefits Statements

HIPAA for explanation of benefits statements includes privacy protections, disclosure limitations, and patient access rights that healthcare providers, payers, and suppliers need to understand when handling these documents. These requirements govern how explanation of benefits forms can be shared, stored, and transmitted while protecting patient information. Healthcare organizations processing explanation of benefits communications encounter specific HIPAA obligations that affect billing workflows, patient communications, and third-party interactions. Understanding HIPAA for explanation of benefits statements helps organizations avoid violations while maintaining efficient claims processing and patient engagement practices.

Privacy Protections in Explanation of Benefits Communications

HIPAA for explanation of benefits statements requires health plans to protect patient information contained within these documents. Explanation of benefits forms contain protected health information including patient names, dates of service, provider details, and treatment codes that qualify for privacy protections under HIPAA regulations. Health insurers processing explanation of benefits must implement safeguards to prevent unauthorized access, use, or disclosure of this information during document creation, transmission, and storage processes. The privacy protections extend to electronic and paper-based explanation of benefits communications. Health plans sending explanation of benefits via email need encryption or secure patient portals to protect information during transmission. When mailing paper explanation of benefits, insurers must use appropriate addressing and packaging to prevent accidental disclosure to unintended recipients. Correct implementation of these privacy measures prevents unauthorized access and maintains patient confidentiality.

Patient Access Rights for Explanation of Benefits Documents

Patients have specific rights under HIPAA regarding their explanation of benefits statements, including the right to receive copies, request corrections, and control how these documents are shared. Health plans must provide explanation of benefits to patients within reasonable timeframes and allow patients to designate how they prefer to receive these communications. Patients can request explanation of benefits in specific formats or ask that copies be sent to alternative addresses when medically necessary or for safety reasons. The right to request amendments applies to explanation of benefits when patients identify errors in treatment descriptions, billing codes, or other information contained within these documents. Health plans must have procedures for handling amendment requests and responding to patients within required timeframes. When approved, health plans must accommodate these requests according to HIPAA timelines and notification procedures.

Disclosure Rules for Explanation of Benefits Information

Health plans face specific disclosure rules when sharing explanation of benefits information with healthcare providers, patients, and third parties. HIPAA allows disclosure of explanation of benefits information for treatment, payment, and healthcare operations without patient authorization, but requires minimum necessary standards to limit information sharing to what is needed for the specific purpose. Healthcare providers can receive explanation of benefits details related to their patients’ claims processing and payment status as part of routine payment operations. Disclosure to family members or personal representatives requires either patient authorization or demonstration that the person has legal authority to act on the patient’s behalf. Health plans cannot share explanation of benefits information with employers, even when the employer sponsors the health plan, without specific patient authorization or as permitted under limited circumstances outlined in HIPAA regulations. Patient privacy remains protected while enabling health plans to conduct necessary payment and administrative activities.

Electronic Transmission Requirements for Explanation of Benefits

Electronic transmission of explanation of benefits requires compliance with HIPAA security standards to protect patient information during digital communication processes. Health plans using email, patient portals, or other electronic methods to deliver explanation of benefits must implement appropriate safeguards including encryption, access controls, and transmission security measures. These requirements apply whether explanation of benefits are sent as attachments, embedded in secure messages, or accessed through online platforms. The security requirements also cover explanation of benefits data stored in electronic systems, requiring health plans to implement administrative, physical, and technical safeguards to protect this information from unauthorized access or disclosure. Audit controls help track who accesses explanation of benefits information and when, providing accountability and helping identify potential security incidents. Organizations benefit from conducting periodic reviews to address emerging security challenges and technology updates.

Business Associate Obligations for Explanation of Benefits Processing

Third-party vendors processing explanation of benefits on behalf of health plans operate as business associates under HIPAA and must comply with specific obligations when handling this protected health information. Business associate agreements must outline how vendors will protect explanation of benefits data, limit its use to authorized purposes, and report any security incidents or unauthorized disclosures. These agreements help ensure that outsourced explanation of benefits processing maintains the same privacy and security protections required of health plans. Business associates processing explanation of benefits must implement appropriate safeguards for the information they handle and ensure that any subcontractors also comply with HIPAA requirements. The obligations include limiting access to explanation of benefits information to authorized personnel, providing security training, and maintaining audit logs of information access and use. Proper contract management and oversight ensure that all parties handling explanation of benefits information maintain appropriate privacy standards.

Compliance Monitoring for Explanation of Benefits Practices

Healthcare organizations need frequent monitoring and assessment of their explanation of benefits practices to ensure continued HIPAA compliance. Regular audits help identify potential gaps in privacy protections, disclosure practices, or security measures that could lead to violations. Training programs help staff understand their responsibilities when handling explanation of benefits information and keep them updated on regulatory changes that affect these communications. Incident response procedures specifically address explanation of benefits-related security breaches or privacy violations, including notification requirements and remediation steps. Documentation of explanation of benefits practices, policies, and training helps demonstrate compliance efforts during regulatory reviews or investigations. Consistent monitoring and documentation create a foundation for sustainable HIPAA compliance across all explanation of benefits operations..

How Automated Workflows Boost Engagement for Healthcare Marketing Campaigns

Due to the fact that it’s simple, instantaneous, cost-effective, and nearly universally adopted, email is an essential part of all healthcare marketing engagement strategies. However, consistent, personalized email engagement – particularly at scale – can be challenging. 

 

Fortunately, Automated Workflows offer a solution, allowing healthcare companies to deliver the right messages to the appropriate individuals at the right time, based on their individual engagement with emails.. 

 

In this post, we’ll explore the concept of Automated Workflows, the considerable benefits they offer healthcare companies, and the variety of ways they can be used to increase engagement and result in greater satisfaction and better healthcare outcomes for your patients and customers.

What Are Automated Workflows?

An Automated Workflow is a sequence of actions, known as’ Steps’ in LuxSci Secure Marketing, that a Contact (i.e., a patient or customer) moves through over time, based on a series of pre-defined rules or triggers. 

 

Each Step is programmed to automatically perform a specific function, such as sending an email or updating a Contact, when certain conditions are in place. These conditions could include: 

  • A Contact opening a message.
  • A Contact clicking through on a link.
  • A specified amount of time having elapsed.. 
  • A data update via an API call

By evaluating conditions to initiate the appropriate Step, Automated Workflows facilitate more timely, consistent, and personalized communication with Contacts (patients and customers ). As a result, healthcare companies can effectively harness Automated Workflows to develop dynamic, personalized email engagement journeys that adapt according to your patients and customers’ needs and prior interactions.

What Are the Benefits of Automated Workflows?

Let’s look at the various advantages that Luxsci Automated Workflows offer. 

Reduced Administrative Workload

Arguably, the most significant benefit of Automated Workflows is the extent to which they lower the administrative burden of email engagement campaigns for healthcare organizations. 

 

First and foremost, Automated Workflows eliminate the need for an employee to manually send your Contacts messages. As well as the manual effort, it removes a great deal of thought from the process – as someone isn’t required to remember to send an email. 

 

By the same token, this reduces the scope for human error, preventing the possibility of an employee neglecting to send an important message, sending it to the wrong person, or worse, accidentally exposing patient data, i.e., electronic protected health information (ePHI). 

 

The effort that Automated Workflows reduce is typically repetitive work that staff are glad to be free of, giving them additional time to focus on tasks that provide greater value and better contribute to better patient care and/or the customer experience. 

Enhanced Scalability

The time saved by employing Automated Workflows increases with the size of your Contact List and the scale of your engagement campaigns. In fact, enterprise-scale campaigns, with volumes of hundreds of thousands to millions of emails, are only feasible through the use of automation. 

 

Similarly, Automated Workflows enable healthcare organizations to run differing, personalized email campaigns aimed at unique patient or customer segments.  As well as automatically sending each message at the appropriate time, they provide tracking capabilities to determine the outcome of each message. 

Increased Consistency in Communication

Because Automated Workflows remediate the risk of emails going unsent, they facilitate more timely and consistent communications with patients and customers. This makes healthcare providers, payers, and suppliers appear more reliable and consistent, building trust and greater levels of satisfaction from Contacts. More importantly, recipients are better able to track what’s happening with their healthcare and assume a more proactive role overall healthcare journey..

 

Finally, creating an Automated Workflow requires healthcare organizations to carefully consider how they communicate with different Contact segments. Namely, the likely journey, or communication path, different types of Contacts take, i.e., information they need to know at a particular stage in their healthcare journey, the optimal order in which information needs to be presented, etc. This allows healthcare companies to become more in-tune with their patients’ and customers’ needs, enabling them to craft more valuable email communications that boost engagement. 

Personalized Healthcare Engagement 

Perhaps the most significant benefit of Automated Workflows is that they enable adaptive, personalized engagement for healthcare marketing and communications campiagns. Instead of manually tracking where each Contact is in a given engagement sequence, or worse, merely having to guess, you know precisely where they are. Consequently, you’re acutely aware of their needs and the exact nature of the emails you need to send them next. 

 

This, in turn, enables more effective Contact nurturing, i.e, strengthening your organization’s connection with each individual. When at its most effective, this may allow you to anticipate your Contacts’ needs, enabling you to send them communications, such screening or testing recommendations, educational materials, or product and service suggestions, that support their healthcare journey and enhance their quality of care.

Automated Workflow Use Cases

Automated Workflows are a powerful tool for increasing healthcare marketing and communications engagement because they can be applied to a wide range of use cases. Let’s take a look at some of the most common and impactful ways email automation can be used by healthcare companies. 

  • New Product Announcements: keeping patients and customers in the loop on your company’s latest offerings, as well as improvements to existing products and services that are likely to be of interest, based on their data and past actions.
  • Personalized recommendations: suggesting products or services based on the recipient’s past purchases or engagement history.
  • Re-Engagement Campaigns: Automated Workflows can also be used to reconnect with Contacts with whom engagement has waned or was never completely established, sending them personalized messages to encourage specific actions or reignite interest.
  • New Member Onboarding: welcoming new patients or customers  with a structured series of emails that introduces your services, provides technical assistance (where applicable), details subsequent steps, and explains how to get the most value from your products or services. 
  • Appointment Reminers and Follow-Ups: sending reminders, care instructions, medication adherence advice, or details on how to book subsequent appointments, for instance, after a patient visit. 
  • Patient Education Campaigns: taking patients through a structured curriculum on managing their medical condition or required  lifestyle changes to improve their health..
  • Preventative Care Communications: proactively sending reminders for screenings, check-ups, vaccinations, etc., based on PHI such as a patient’s age, gender, health condition or lifestyle risk factors.
  • Milestone Communications: sending personalized messages to acknowledge birthdays, enrollment anniversaries, and other pertinent dates. These can also be combined with preventative care communications, to send recommendations or other advice, based on the contact’s age, for instance.  
  • Feedback Collection: acquiring patient and customer feedback by sending follow-up surveys a set amount of time after a visit, procedure, purchase, etc. 

How Automated Workflows Work in LuxSci Secure Marketing

To round off this post, let’s take a deeper look at how Automated Workflows work within LuxSci’s Secure Marketing solution. LuxSci’s Automated Workflows enhance your organization’s HIPAA compliant healthcare marketing and email campaigns by giving you complete control of:

 

  • When each email is sent
  • Which Contacts receive particular communications according to their behavior, needs, and other PHI-based attributes
  • Which engagement path or branch a Contact takes based on their email actions

Here’s a look at LuxSci’s Automated Workflows key capabilities in greater detail. 

Smart Event-Based Branching and Conditions

You can branch Workflows to trigger targeted messaging based on a Contact’s attributes or certain engagement events, resulting in more relevant and effective healthcare journeys  with more desirable outcomes.

  • User actions:
    • Mailing list sign-ups
    • Form completion
    • Downloading a resource.
  • Time-based triggers:
    • A set period after a visit or procedure 
    • A defined period of inactivity or lack of contact
    • Milestones, e.g., birthdays, anniversaries. 
  • Behavioral triggers:
    • Email opens
    • Clicking on links
    • Visiting particular pages on a site or 
    • A lack of engagement with previous emails.
  • Transactional triggers:
    • Purchasing a product or service
    • Signing up for an event
    • Order confirmations or shipping updates after a purchase.
  • API-triggered events
    • Lab results or similar correspondence becoming available
    • Changes to data in EHR systems, CDP platforms, or CRM systems.. 

Automated Segment Management 

Automated Workflows can be used to dynamically add Contacts to segments based on demographics, past behavior, purchase history, and similar events. This enables more precise targeting and email personalization as they progress through specific Steps in each Workflow. 

Navigation Across Steps

Automated Workflows are also capable of navigating Contacts across different Steps or completely different Workflows depending on engagement outcomes and updates to a Contact’s PHI. Better still, if a Step has already been visited, LuxSci Secure Marketing automatically prevents repetition and infinite loops.

Healthcare marketing plan

How To Create a Healthcare Marketing Plan?

A healthcare marketing plan establishes strategic promotional activities, target audience identification, budget allocation, and compliance protocols to attract new patients while adhering to HIPAA privacy regulations and state advertising laws. Medical practices develop these documents to guide their promotional efforts across digital platforms, traditional media, and community outreach programs, ensuring all patient acquisition activities comply with healthcare privacy requirements and professional advertising standards.

Medical practices compete intensely for patient attention in saturated healthcare markets. Developing promotional strategies without proper planning leads to wasted resources, compliance violations, and missed opportunities to connect with patients who need specific medical services.

Target Audience in Healthcare Marketing Plan Development

Patient demographic research identifies age groups, geographic locations, insurance coverage types, and medical conditions that align with practice specialties and service offerings. Healthcare organizations analyze existing patient data to understand referral patterns, appointment scheduling preferences, and communication channel effectiveness for different population segments.

Competitor analysis reveals promotional strategies used by similar practices, pricing structures for comparable services, and market gaps that create opportunities for differentiation. This research helps practices position their services uniquely while avoiding oversaturated promotional approaches that fail to generate meaningful patient engagement.

Budget Allocation

Financial planning allocates resources across promotional channels based on expected return on investment, patient acquisition costs, and practice revenue goals. Digital advertising usually receives 40-60% of promotional budgets due to measurable results and targeted audience capabilities, while traditional media and community events receive smaller allocations.

Compliance costs including legal reviews, authorization management, and privacy training must be factored into promotional budgets to ensure all activities meet regulatory requirements. Practices that underestimate compliance expenses often discover their promotional activities violate privacy laws or professional advertising standards.

Digital Strategy to Drive Modern Patient Acquisition

Website optimization, search engine marketing, and social media presence are the core of contemporary promotional efforts outlined in every healthcare marketing plan. Practices invest in professional website design, patient portal integration, and mobile-responsive layouts to capture patients researching medical services online.

Content creation including blog posts, educational videos, and patient resources helps establish expertise while providing valuable information to potential patients. However, all content must avoid using patient information without authorization and cannot make unsubstantiated medical claims that violate advertising regulations.

Compliance Integration Protects Promotional Activities

HIPAA authorization procedures, business associate agreements with promotional vendors, and state advertising law compliance must be woven throughout every aspect of promotional planning. Healthcare marketing plan development includes legal review processes, privacy impact assessments, and staff training protocols to prevent violations.

Documentation requirements for promotional activities include consent forms, vendor contracts, and approval workflows that demonstrate compliance with healthcare privacy laws. Practices without proper documentation face significant penalties when regulatory investigations uncover promotional activities that violate patient privacy protections.

Community Outreach Builds Local Patient Relationships

Health fairs, educational seminars, and community partnerships create opportunities for practices to connect with potential patients through face-to-face interactions. These activities require planning to ensure patient privacy protection while maximizing promotional impact through relationship building and trust development.

Referral programs with other healthcare providers, local businesses, and community organizations can generate new patient leads when structured appropriately. Any financial incentives for referrals must comply with healthcare fraud and abuse laws to avoid legal complications.

Performance Measurement Guides Strategy Optimization

Patient acquisition metrics, appointment conversion rates, and promotional channel effectiveness data help practices evaluate their promotional success and adjust strategies accordingly. Healthcare marketing plan implementation includes tracking systems for website traffic, phone inquiries, and new patient appointments generated by different promotional activities.

Return on investment calculations compare promotional spending with revenue generated from new patients to determine which activities provide the best financial results. Practices use this data to reallocate budgets toward high-performing promotional channels while eliminating ineffective strategies.

Implementation Timeline

Monthly promotional calendars coordinate campaign launches, content publication schedules, and community event participation to maximize promotional impact while avoiding resource conflicts. Healthcare marketing plan execution requires detailed project management to ensure all activities launch on schedule and within budget constraints. Seasonal considerations including flu shot campaigns, wellness check promotions, and holiday health messaging opportunities require advance planning to capitalize on increased patient interest during specific time periods. Practices that plan these campaigns well in advance may achieve better results than those that react to opportunities without preparation.

HIPAA Marketing Rule

What Does the HIPAA Marketing Rule Require?

The HIPAA marketing rule prohibits healthcare organizations from using protected health information for promotional communications without written patient authorization, defining promotional activities as communications that encourage patients to purchase products or services with financial benefit to the sender. Organizations can send treatment-related communications, appointment reminders, and health plan benefit descriptions without authorization, but any communication promoting third-party products, paid services, or revenue-generating activities requires explicit patient consent through properly executed authorization forms.

Healthcare providers regularly find themselves struggling with acceptable patient education and prohibited promotional activities. A simple newsletter about diabetes management becomes problematic when it includes advertisements for glucose monitors or pharmaceutical products that generate revenue for the practice.

The HIPAA Marketing Rule Authorization Framework

Patient authorization documents must contain sixteen specific elements including detailed descriptions of information to be disclosed, identification of recipients, expiration dates, and explanations of revocation rights. These forms cannot be combined with other consent documents and must use plain language that patients can easily understand. Healthcare organizations face penalties when authorization forms lack required elements or contain overly broad permission language.

Patients retain the right to revoke authorization at any time, forcing organizations to immediately cease all promotional activities involving that individual’s information. Organizations cannot condition treatment, payment, enrollment, or benefits eligibility on patients providing authorization for promotional purposes, creating clear separation between healthcare services and commercial activities.

Treatment Communications Bypass Marketing Restrictions

Healthcare organizations can discuss treatment alternatives, medication options, and care coordination services without obtaining separate authorization because these communications serve legitimate healthcare purposes rather than commercial interests. Appointment scheduling, test result notifications, and prescription refill reminders fall under treatment or healthcare operations exemptions from marketing regulations.

Face-to-face communications between providers and patients about treatment options is unrestricted, even when providers receive financial benefits from recommended treatments or services. Written materials distributed during these encounters may trigger authorization requirements if they promote specific products or services beyond the immediate treatment relationship.

Financial Incentive Distinctions Shape HIPAA Marketing Rule Compliance

Communications become subject to the HIPAA marketing rule when healthcare organizations receive financial remuneration from third parties for promoting their products or services. Pharmaceutical company payments for promoting medications, medical device manufacturer incentives, or referral fees from specialty services transform otherwise acceptable communications into restricted promotional activities.

Organizations must examine their financial relationships carefully to determine when communications cross from permissible healthcare operations into restricted promotional territory. Even nominal payments or gifts from third parties can trigger marketing authorization requirements for communications that mention or promote those parties’ products or services.

Business Associate Relationships Complicate Marketing Activities

Vendors creating promotional materials, managing patient outreach campaigns, or analyzing treatment data for commercial purposes need business associate agreements before accessing PHI. These relationships are difficult if the promotional vendors also provide healthcare services or when healthcare organizations share revenue from marketing activities with their business partners.

Organizations must negotiate appropriate contractual protections and ensure vendors understand their obligations under the HIPAA marketing rule before beginning any collaborative promotional activities. Liability for vendor violations remains with the covered entity, making careful partner selection and monitoring essential for maintaining compliance.

Digital Platforms & Modern Marketing Compliance Challenges

Social media advertising, email campaigns, and online retargeting involve sharing patient information with technology platforms that lack appropriate privacy protections. Healthcare organizations cannot upload patient contact lists, demographic details, or treatment information to advertising platforms without proper authorization and business associate agreements covering those platforms.

Website analytics, social media pixels, and advertising tracking technologies may inadvertently capture and transmit PHI to third-party platforms without appropriate protections. Organizations need controls to prevent accidental information sharing while still enabling effective digital marketing activities within compliance boundaries.

Enforcement Penalties Reflect Serious Violation Consequences

Recent Office for Civil Rights enforcement actions have resulted in multi-million dollar settlements for organizations that used patient information in marketing materials without authorization or shared PHI with advertising vendors without appropriate agreements. These cases highlight increasing federal scrutiny of healthcare promotional activities and willingness to impose substantial financial penalties.

Violations may stem from seemingly innocent activities like patient newsletters, social media posts, or website testimonials that inadvertently disclosed PHI without proper authorization. Organizations discover that good intentions cannot shield them from penalties when their marketing activities violate patient privacy protections under the HIPAA marketing rule.

Compliance Programs Minimize Violation Risks

Healthcare organizations benefit from establishing clear review processes for all promotional materials and patient communications before distribution. Designated privacy personnel can evaluate whether proposed communications require authorization, involve business associate relationships, or create other compliance risks under marketing regulations.

Staff training helps employees recognize the difference between permissible healthcare communications and restricted marketing activities. Education updates keep pace with new promotional channels, emerging technology platforms, and evolving interpretations of the rule’s requirements within changing healthcare and advertising landscapes.

Why Healthcare Insurers Should Send Explanation of Benefits Statements Via Email

Explanation of Benefits statements or EOBs are mission-critical communications for health insurers because they ensure transparency, help detect billing errors or fraud, and most importantly, keep patients informed about their benefits and related payments.

 

However, the most conventional method of sending out EoBs, traditional mail, has several drawbacks that can prevent important information about healthcare coverage from reaching the intended recipient. This can leave policyholders in the dark about their healthcare coverage, which can lead to confusion and dissatisfaction with their insurance provider when they receive an unexpected medical bill. This can also drive up inbound calls into your claims department or contact center.

 

Because Explanation of Benefits statements contain the protected health information (PHI) of policyholders, insurers are bound by HIPAA (the Health Insurance Portability and Accountability Act) regulations to ensure their secure delivery. Consequently, the risks inherent to sending paper EoB statements in the mail not only have security implications but also potential consequences for non-compliance.

 

With all this in mind, this post discusses why healthcare insurers should send EoBs to their policyholders via secure email instead of traditional mail. We detail the various benefits of making the switch to electronic EoBs, which include enhanced security, better adherence to compliance regulations, and the opportunity to save millions of dollars per month.

 

Protecting Patient Privacy

The primary reason that insurance companies should shift to email EoBs as opposed to traditional mail is that it’s far more secure. Sending an EoB via email drastically decreases the risk of protected health information (PHI) getting into the wrong hands. When sent in paper form by mail, an EoB could be:

 

  • Lost, stolen or damaged in transit
  • Delivered to the wrong address
  • Not properly deposited in a letter or mailbox, then stolen
  • Intercepted within the intended address by another individual who lives at or has access to the residence. 

As detailed later in this post, email also allows for various controls and processes, which mitigate the risks of unsuccessful message delivery.

 

Most importantly, secure email provides data encryption, which safeguards the sensitive patient data within EoBs during transmission and when stored by rendering it unreadable to malicious actors who might intercept it. Physical mail, in contrast, offers no such protection, as someone who intercepts a paper EoB form can simply open it and freely read its contents.

 

Finally, secure email delivery platforms feature identity verification and access controls that enable healthcare insurers to restrict access to PHI to authorized personnel, limiting its exposure. They also provide auditing capabilities to track access to patient data, and quickly identify the source of security breaches.

HIPAA Compliance Benefits

Because sending an Explanation of Benefits statement via email is more secure, and better protects any patient data contained within them, this also reduces the risk of HIPAA compliance violations.

 

First and foremost, HIPAA regulations mandate that communications containing PHI, such as EoBs, must securely reach the intended recipient. By eliminating the risk of physical interception or non-delivery, and the compliance violations from a resulting security breach, insurers can better adhere to HIPAA regulations using email for sending EOBs. On a similar note, the security features built into a HIPAA compliant email platform, such as encryption, access controls, and audit logs, help insurers to satisfy the requirements of HIPAA’s Privacy and Security Rules in their compliance efforts.

 

Another considerable benefit of using secure email to send policyholders their EoBs, or, in fact, any communication containing PHI, is that it’s far easier to implement breach notification protocols. Email delivery platforms provide real-time tracking, so companies can pinpoint email message failures quickly and act accordingly. Similarly, intrusion detection systems and other cybersecurity measures that support email systems can enable faster detection and containment of data breaches.

 

In stark contrast, physical mail is far more difficult to track – and even those limited capabilities are reserved for more expensive delivery options. Consequently, security breaches via mail could go unnoticed for days or even weeks. If you’re unaware of a data breach, or have not yet contained or mitigated it, you’re then unable to inform all affected parties, resulting in further HIPAA violations.

Increased Deliverability Rates

By greatly mitigating the security risks presented by physical mail, i.e., the various ways an EoB could fall into the wrong hands, sending an EoB by email increases your ability to get more EOBs into the hands of policyholders, more quickly. At the same time, policyholders can make faster decisions regarding their healthcare.

The ability to track secure email gives you greater control over EOB deliverability, as it allows organizations to determine the cause of delivery failure and can also make subsequent attempts. Additionally, the process of determining the reason for the message delivery failures can also reveal security issues; the same process, however, is very difficult to achieve with traditional mail.

 

Here’s how the typical protocol for resending a secured email goes beyond what you can do with managing traditional mail delivery:

 

  • Determine the cause of non-delivery: verify that the intended recipient information is correct and check for issues like a full email inbox or security misconfigurations. 
  • Don’t automatically resend: to avoid exposing PHI to the wrong person, confirm the intended recipient’s email address through an alternative verified channel, e.g., phone call, secure SMS, etc. 
  • Log the incident: document the delivery failure, steps taken to determine its cause, attempts, etc.
  • Reattempt message delivery: if the investigation deems it safe, attempt message redelivery with the corrected information. 

In the event that subsequent delivery attempts fail, it’s best practice to contact the individual to arrange the most convenient and secure alternative to deliver their EoBs. 

Cost Savings 

Simply put, sending Explanation of Benefits statements via email instead of traditional mail saves health insurers money – potentially lots of it. Processing EOBs from start to finish can cost health insurers one to two dollars or more per EOB. That’s a lot. The biggest opportunity for cost reduction is tied to the money saved on printing and mailing paper EoB statements. Additionally, the cost of administering the delivery of EoB forms, ensuring their delivery, etc., is lowered when it’s done electronically. Not to mention, resending EoBs in the event of their non-delivery is much easier and cheaper via email.

 

In a broader sense, increasing the deliverability and the success rate of sending EoBs helps a larger number of policyholders better understand the details of their insurance coverage, i.e., how it works, which services and procedures it covers, etc. As a result of their policyholders being more informed, insurers won’t spend as much time explaining policy details and cost breakdowns to their members, allowing them to divert the otherwise required resources to other areas of the business.  

Reduced Carbon Footprint

Finally, it’s difficult to highlight the benefits of sending EoBs to policyholders by email without recognizing the positive environmental impact, too. Email EoBs cut down on paper, for both the forms themselves and the envelopes they’re mailed in. Then there’s the matter of the electricity and ink involved in printing them, the emissions produced in their delivery, etc. Opting to send EoBs via email reduces all these factors, which enables healthcare organizations to lower their carbon footprint and, where applicable, meet their sustainability obligations or goals.

What Is a HIPAA Compliant Email API?

HIPAA compliant email API enables healthcare applications to send automated emails containing protected health information through secure programming interfaces that meet HIPAA Security Rule requirements. These APIs provide encryption, access controls, and audit logging capabilities while allowing developers to integrate email functionality into healthcare software without compromising patient privacy or regulatory compliance. Healthcare software applications increasingly need automated email capabilities for appointment reminders, test results, billing notifications, and care coordination communications. Standard email APIs lack the security features and compliance controls necessary for transmitting PHI, requiring specialized solutions designed for healthcare use cases.

API Authentication and Access Controls

HIPAA compliant email APIs implement robust authentication mechanisms that verify the identity of applications and users before allowing access to email services. These systems typically use API keys, OAuth tokens, or digital certificates to establish secure communication channels between healthcare applications and email services. Role-based access controls allow healthcare organizations to limit API functionality based on user privileges and business needs. Appointment scheduling systems might have permission to send calendar reminders while being restricted from accessing patient medical records or billing information. Rate limiting and usage tracking help prevent unauthorized bulk email sending and detect potential security threats. API providers monitor usage patterns and can automatically restrict access when they detect unusual activity that might indicate compromised credentials or malicious use.

Message Encryption and Security Features

Email messages sent through HIPAA compliant APIs receive automatic encryption during transmission and storage. These systems typically support multiple encryption standards including TLS for transport security and end-to-end encryption for message content protection. Message validation features help ensure that emails containing PHI meet compliance requirements before transmission. APIs can check for proper authorization, validate recipient addresses, and verify that message content follows organizational policies for PHI disclosure.

Secure message delivery tracking provides confirmation when recipients receive and access encrypted emails. This audit trail helps healthcare organizations demonstrate compliance with HIPAA requirements and provides documentation for potential breach investigations or regulatory audits.

Integration with Healthcare Workflows

HIPAA compliant email APIs connect seamlessly with electronic health record systems, practice management platforms, and other healthcare applications. These integrations enable automated patient communications that trigger based on clinical events, scheduling changes, or administrative milestones. Template management systems allow healthcare organizations to create standardized email formats that ensure consistent messaging while maintaining compliance controls. Templates can include dynamic content from patient records while preventing unauthorized PHI disclosure through automated formatting rules. Event-driven messaging capabilities enable real-time communications based on healthcare system activities. Laboratory systems can automatically send encrypted test results to ordering physicians immediately after completion, improving care coordination and reducing manual data entry requirements.

Audit Logging and Compliance Tracking

HIPAA compliant email APIs maintain detailed logs of all messaging activities including sender identification, recipient information, message content summaries, and delivery status. These logs provide the documentation necessary for compliance audits and breach investigations. Automated compliance reporting features help healthcare organizations track email usage patterns and identify potential policy violations. Reports can highlight unusual sending volumes, unauthorized recipient addresses, or messages that might contain inappropriate PHI disclosures.

Data retention policies ensure that API logs and message archives meet HIPAA requirements while managing storage costs and system performance. Healthcare organizations can configure retention periods based on their compliance needs and operational requirements.

Developer Tools and Documentation

API documentation provides healthcare software developers with detailed technical specifications, code samples, and integration guides for implementing HIPAA compliant email functionality. These resources help development teams understand security requirements and implement proper PHI handling procedures. Software development kits (SDKs) simplify API integration by providing pre-built libraries for common programming languages and frameworks. These tools handle encryption, authentication, and compliance features automatically, reducing the risk of implementation errors that could compromise PHI security. Testing environments allow developers to validate their integrations without exposing real patient data. Sandbox systems provide realistic API responses while using synthetic data that enables thorough testing of email functionality and error handling procedures.

Scalability and Performance Considerations

HIPAA compliant email APIs must handle varying message volumes without compromising security or compliance controls. Healthcare organizations experience different email patterns based on patient schedules, clinical activities, and administrative cycles that require flexible capacity management. Load balancing and redundancy features ensure reliable email delivery even during peak usage periods or system maintenance activities. API providers typically maintain multiple data centers and failover systems that prevent service disruptions from affecting patient communications.

Performance analytics help healthcare organizations optimize their email communications and identify potential bottlenecks in their workflows. Metrics include delivery speeds, error rates, and system response times that enable proactive performance management and capacity planning.

Is WhatsApp HIPAA Compliant?

WhatsApp is not HIPAA compliant for healthcare communications containing protected health information. Despite offering end-to-end encryption, WhatsApp lacks several required elements for HIPAA compliance, including Business Associate Agreements, adequate access controls, and audit logging. Healthcare organizations cannot legally use standard WhatsApp to communicate patient information without risking regulatory violations and potential penalties under HIPAA compliant enforcement rules.

WhatsApp Encryption and Security Features

WhatsApp provides end-to-end encryption that protects message content during transmission between users. This encryption prevents even WhatsApp itself from accessing message contents, creating a basic level of confidentiality. Two-factor authentication adds protection against unauthorized account access. Message deletion capabilities allow removing content after sending. Screenshot blocking in disappearing messages mode prevents certain forms of message capture. Device linking requires biometric or PIN verification when connecting new devices to accounts. While these security features offer protection for personal communications, they fall short of the structured safeguards required for HIPAA compliant healthcare messaging.

Missing Business Associate Agreement

Meta (WhatsApp’s parent company) does not offer Business Associate Agreements for standard WhatsApp accounts. This absence creates an insurmountable barrier to becoming HIPAA compliant, regardless of any security features or usage policies implemented. Without a BAA establishing WhatsApp as a business associate under HIPAA compliant regulations, healthcare organizations cannot legally use the platform for communications containing protected health information. The WhatsApp terms of service make no provisions for healthcare regulatory compliance or protected health information handling. Healthcare organizations seeking compliant messaging must select platforms from providers willing to enter into appropriate contractual relationships governing healthcare data.

Access Control and Authentication Limitations

WhatsApp lacks the granular access controls needed for healthcare communications. The platform offers limited ability to manage which users can access specific conversations beyond simple group membership. Administrative oversight tools for organizational accounts fall short of healthcare requirements for managing user permissions. Account access remains tied primarily to phone numbers rather than organizational identity systems. The platform lacks integration with enterprise authentication systems used in healthcare settings. Message visibility cannot be restricted based on staff roles or need-to-know principles within healthcare teams. Organizations cannot implement the access management hierarchies typically needed for proper information governance in clinical environments.

Audit and Compliance Documentation Challenges

HIPAA compliance requires detailed records of who accessed information and when this access occurred. WhatsApp provides limited message delivery and reading confirmations but lacks comprehensive audit logs needed for regulatory compliance. The platform offers no administrative portal for reviewing user activities across an organization. Message history may be lost during device changes or app reinstallation. Organizations cannot generate compliance reports showing message handling patterns. Data retention controls do not align with healthcare recordkeeping requirements. Without proper audit capabilities, healthcare organizations cannot demonstrate compliance with HIPAA access monitoring requirements or investigate potential security incidents involving patient information.

Data Management and Retention Issues

WhatsApp creates several data management challenges that conflict with HIPAA requirements. The platform automatically saves received media to users’ personal devices, potentially exposing protected health information. Backup settings may send message history to personal cloud storage accounts outside organizational control. Message deletion features allow recipients to remove content without administrator knowledge. Data retention periods cannot be centrally managed to align with healthcare recordkeeping policies. The platform lacks classification tools for identifying which conversations contain protected health information. Organizations cannot implement consistent data lifecycle management across all communications containing patient information.

Compliant Alternatives to WhatsApp

Healthcare organizations requiring HIPAA compliant messaging should implement appropriate alternatives to WhatsApp. Platforms like TigerConnect, Spok, and Halo Health provide secure messaging designed specifically for healthcare environments. Many electronic health record systems include compliant messaging components within their patient care applications. Telehealth platforms offer secure communication channels as part of virtual visit workflows. Enterprise communication platforms like Microsoft Teams can support HIPAA compliant messaging when properly configured and covered by appropriate agreements. These alternatives provide the necessary security features, administrative controls, and compliance documentation needed for healthcare communications containing protected health information.

Limited Acceptable Use Cases

WhatsApp may have limited acceptable use cases within healthcare environments when properly restricted. Administrative communications that never include patient information can utilize the platform with clear policies prohibiting any protected health information. Public health outreach and general wellness information that contains no individually identifiable health data may be appropriate for WhatsApp distribution. Patient communications through WhatsApp should occur only when patients have been clearly informed of privacy limitations and have explicitly chosen this communication method despite its risks.

Is the Email Encrypted? How to Tell if an Email is Transmitted Using TLS

SMTP TLS encryption is popular because it provides adequate data protection without creating a complicated user experience for email recipients. Sometimes, though, the experience is too seamless, and recipients may wonder if the message was protected at all.

Luckily, there is a way to tell if an email was encrypted using TLS. To see if a message was sent securely, we can look at the raw headers of the email. However, it requires some knowledge and experience to understand the text. It is actually easier to tell if a recipient’s server supports TLS than to tell if a particular message was securely transmitted.

To analyze a message for transmission security, we will look at an example email message sent from Hotmail to LuxSci. We will explain what to look for when decoding the message headers and how to tell if the email was transmitted using TLS encryption.

An Example Email Message

First, we must understand how an email message typically travels through several machines on its way from the sender to the recipient. Roughly speaking:

  1. The sender’s computer talks to the sender’s email or WebMail server to upload the message.
  2. The sender’s email or WebMail server then talks to the recipient’s inbound email server and transmits the message to them.
  3. Finally, the recipient downloads the message from their email server.

It is step 2 that people are most concerned about when trying to understand if their email message is transmitted securely. They usually assume or check that everything is secure and OK at the two ends. Indeed, most users who need to can take steps to ensure that they are using SSL-enabled WebMail or POP/IMAP/SMTP/Exchange services so that steps 1 and 3 are secure. The intermediate step, where the email is transmitted between two different providers, is where messages may be sent insecurely.

To determine if the message was transmitted securely between the sender’s and recipient’s servers (over TLS), we need to extract the “Received” header lines from the received email message. If you look at the source of the email message, the lines at the top start with “Received.” Let’s look at an example message from a Hotmail user below. The email addresses, IPs, and other information are obviously fake.

LuxSci:

The Outlook email was sent to a LuxSci user. The Received headers appear in reverse chronological order, starting with the server that touched the message last. Therefore, in this example, we see the LuxSci servers first.

Received: from abc.luxsci.com ([1.1.1.1])
	by def.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfLgH003867
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 10:41:21 -0400
Received: from abc.luxsci.com (localhost.localdomain [127.0.0.1])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfK0Z030182
	for <user-xyz@def.luxsci.com>; Mon, 19 Aug 2019 09:41:20 -0500
Received: (from mail@localhost)
	by abc.luxsci.com (8.14.4/8.13.8/Submit) id r7JEfKXD030178
	for user-xyz@def.luxsci.com; Mon, 19 Aug 2019 09:41:20 -0500
Received: from dispatch1-us1.ppe-hosted.com (dispatch1-us1.ppe-hosted.com [2.2.2.2])
	by abc.luxsci.com (8.14.4/8.13.8) with ESMTP id r7JEfIkK030002
	(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)
	for <someone@luxsci.net>; Mon, 19 Aug 2019 09:41:19 -0500

Proofpoint:

LuxSci uses an email filtering service, Proofpoint. Messages reach Proofpoint’s servers before being delivered to LuxSci. Here’s what their servers report about the email transmission:

Received: from unknown [65.54.190.216] (EHLO bay0-omc4-s14.bay0.hotmail.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (envelope-from <someone@hotmail.com>);
	Mon, 19 Aug 2019 08:41:18 -0600 (MDT)

Outlook:

And finally, here’s what we see from Oultook’s server.

Received: from BAY403-EAS373 ([65.54.190.199]) by bay0-omc4-s14.bay0.outlook.com
       with Microsoft SMTPSVC(6.0.3790.4675); 
       Mon, 19 Aug 2019 07:41:19 -0700

How to Use Received Message Headers to Tell if the Email is Encrypted

The message headers contain information that can help us determine if an email is encrypted. Here are a few helpful notes to help you decode the text:

  1. We said this above, but the message headers appear in reverse chronological order. The first one listed shows the last server that touched the message; the last one is the first server that touched it (typically the sending server).
  2. Each Received line documents what a server did and when.
  3. There are three sets of servers involved in this example: one machine at Hotmail, one machine at Proofpoint, where our Premium Email Filtering takes place, and some machines at LuxSci, where final acceptance of the message and subsequent delivery happened.

Presumably, the processing of email within each provider is secure. The place to be concerned about is the hand-offs between Hotmail and Proofpoint and between Proofpoint and LuxSci, as these are the big hops across the internet between providers.

In the line where LuxSci accepts the message from Proofpoint, we see:

(version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NOT)

This section, typical of most email servers running “sendmail” with TLS support, indicates that the message was encrypted during transport with TLS using 256-bit AES encryption. (“Verify=not” means that LuxSci did not ask Proofpoint for a second SSL client certificate to verify itself, as that is not usually needed or required for SMTP TLS to work correctly). Also, “TLSv1/SSLv3” is a tag that means that “Some version of SSL or TLS was used;” it does not mean that it was SSL v3 or TLS v1.0. It could have been TLS v1.2 or TLS v1.3.

So, the hop between Proofpoint and LuxSci was locked down and secure. What about the hop between Hotmail and Proofpoint? The Proofpoint server’s Received line makes no note of security at all! This means that the email message was probably not encrypted during this step.

Hotmail either did not support opportunistic TLS encryption for outbound emails, or Proofpoint did not support receipt of messages over TLS, and thus, TLS could not be used. With additional context, you can know which server supports TLS and which does not.

In this case, we know that Proofpoint supports inbound TLS encryption. In fact, from another example message where LuxSci sent a message to Proofpoint, we see the Received line:

Received: from unknown [44.44.44.44] (EHLO wgh.luxsci.com)
	by dispatch1-us1.ppe-hosted.com.ppe-hosted.com
        (using TLSv1.2 with cipher ECDHE-RSA-AES256-GCM-SHA384 (256/256 bits))
	with ESMTP id b-022.p01c11m003.ppe-hosted.com
        (envelope-from <from@domain.com>);
	Mon, 02 Feb 2009 19:28:27 -0700 (MST)

The red text makes it clear that the message was indeed encrypted. Based on the additional context, we can deduce that the Hotmail sending server did not securely transmit the email using TLS.

How To Tell if an Email is Encrypted With TLS

  1. When analyzing your message headers, consider the following items to determine if the email is encrypted:
    1. The receiving server will log what kind of encryption, if any, was used in receiving the message in the headers.
    2. Different email servers use different formats and syntax to display the encryption used. Look for keywords like “SSL,” “TLS,” and “Encryption,” which will signify this information.
    3. Not all servers will record the use of encryption. While LuxSci has always logged encryption use, not every email service provider does. It is possible to use TLS encryption and not log it. Sometimes, there is no way to tell from the headers if a message is encrypted if it is not logged.
    4. Messages passed between servers at the same provider do not necessarily need TLS encryption to be secure. For example, LuxSci has back-channel private network connections between many servers so that information can be securely passed between them without SMTP TLS. So, the lack of TLS usage between two servers does not mean the transmission between them was “insecure.” You may also see multiple received lines listing the same server: the server passes the message between different processes within itself. This communication also does not need to be TLS encrypted.
    5. If you are a LuxSci customer, you can view online email delivery reports to see if TLS was used for any particular message. We record the kind of encryption in the delivery reports, so it’s easy to see which emails were encrypted.

How can you Ensure Emails Are Securely Transmitted?

With some servers not recording TLS in message headers, how can you determine if a message was transmitted securely from sender to recipient?

To answer this question accurately, you must understand the properties, servers, and networks involved. It may be easy to determine that the message was transmitted securely if included in the header information. However, the absence of information does not necessarily mean the message was insecurely transmitted. You can only know this if you know what each system’s servers record.

In our example of a message from Hotmail to LuxSci, you need to know that:

  1. Proofpoint and LuxSci will always log the use of TLS in the headers. We can infer that the Hotmail to Proofpoint transmission was not secure as nothing was recorded there.
  2. The transmission of messages within LuxSci’s infrastructure is secure due to private back channel transmissions. So, even though there is no mention of TLS in every Received line after LuxSci accepts the message from Proofpoint (in this example), transferring the messages between servers in LuxSci is as secure as using TLS. Also, the same server can add multiple received lines as it talks to itself. Generally, these hand-offs on the same server will not use TLS, as there is no need. In the LuxSci example, we see this as “abc.luxsci.com” adds several headers.
  3. We don’t know anything about Hotmail’s email servers, so we don’t know how secure the initial transmissions within their network are. However, since we know they did not securely transmit the message to Proofpoint, we are not confident that the transmissions and processing within Hotmail (which may have gone unrecorded) were secure.

Was the email message sent and received using encryption?

We skipped steps 1 and 3 and focused on step 2 – the transmission between servers. Steps 1 and 3 are equally, if not more, necessary. Why? Because eavesdropping on the internet between ISPs is less of a problem than eavesdropping near the sender and recipient (i.e., in their workplace or local wireless hotspot). So, it’s essential to ensure messages are sent securely and received securely. This means:

  • Sending: Use SMTP over SSL or TLS when sending messages from an email client or use WebMail over a secure connection (HTTPS).
  • Receiving: Ensure your POP or IMAP connection is secured via SSL or TLS. If using WebMail to read your email, be sure it is over a secure connection (HTTPS).
  • WebMail: There is generally no record in the email headers to indicate if a message sent using WebMail was transmitted from the end-user to WebMail over a secure connection (SSL/HTTPS).

You can typically control one side and ensure it is secure; you can’t control the other without taking extra steps. So, what can you do to ensure your message is secure even if it might not be transmitted with encryption or if the recipient tries to access it insecurely?

You could use end-to-end email encryption (like PGP or S/MIME, which are included in SecureLine) or a secure web portal that doesn’t require the recipient to install or set up anything to get your secure email message. These methods meet HIPAA and other regulatory compliance requirements for secure data transmission and provide complete confidence that the message will be sent and received securely.

LuxSci’s SecureLine offers flexible encryption options, including TLS, secure web portal, PGP, and S/MIME. Its dynamic capabilities can determine what types of encryption the recipient’s server supports to ensure your emails are always sent securely.

How to Secure SMTP Email Delivery with TLS

Secure email sending is a priority for organizations that communicate sensitive data externally. One of the most common ways to send secure emails is with SMTP TLS. TLS stands for Transport Layer Security and is the successor of SSL (Secure Socket Layer). TLS is one of the standard ways that computers on the internet transmit information over an encrypted channel. In general, when one computer connects to another computer and uses TLS, the following happens:

  1. Computer A connects to Computer B (no security)
  2. Computer B says “Hello” (no security)
  3. Computer A says, “Let’s talk securely over TLS” (no security)
  4. Computers A and B agree on how to do this (secure)
  5. The rest of the conversation is encrypted (secure)

In particular:

  • The conversation is encrypted
  • Computer A can verify the identity of Computer B (by examining its SSL certificate, which is required for this dialog)
  • The conversation cannot be eavesdropped upon (without Computer A knowing)
  • A third party cannot modify the conversation
  • Third parties cannot inject other information into the conversation.

TLS and SSL help make the internet a more secure place. One popular way to use TLS is to secure SMTP to protect the transmission of email messages between servers.

Secure SMTP Email Delivery with TLS 

The mechanism and language by which one email server transmits email messages to another email server is called Simple Mail Transport Protocol, or SMTP. For a long time, email servers have had the option of using TLS to transparently encrypt the message transmission from one server to another.

When available, using TLS with SMTP ensures the message contents are secured during transmission between the servers. Unfortunately, not all servers support TLS! Many email providers, especially free or public ones, have historically not supported TLS. Thankfully, the trend is shifting. LuxSci found that most providers now support TLS- approximately 85% of domains tested as of July 2022.

Using TLS requires that the server administrators:

  1. purchase SSL certificates
  2. configure the email servers to use them (and keep these configurations updated)
  3. allocate additional computational resources on the email servers involved.

For TLS transmission to be used, the destination email server must offer support for TLS, and the sending computer or server must be configured to use TLS connections when possible.

The sending computer or server could be configured for:

  1. No TLS: never use it.
  2. Opportunistic TLS: use it if available; if not, send it insecurely.
  3. Forced TLS: use TLS or do not deliver the email at all.

How Secure is Email Delivery over SMTP TLS?

TLS protects the transmission of the email message contents. It does nothing to protect the security of the message before it is sent or after it arrives at its destination. For that, other encryption mechanisms may be used, such as PGP, S/MIME, or storage in a secure portal.

For sending sensitive information to customers, transmission security is the minimum standard for compliance with healthcare and financial regulations. TLS is appropriate to meet most compliance requirements and offers an excellent alternative to more robust and less user-friendly encryption methods (like PGP and S/MIME).

There are different versions of TLS- 1.0 and 1.1 use older ciphers and are not as secure, while TLS 1.2 and 1.3 use newer ciphers and are more secure. When an email is sent, the level of TLS used is as secure as can be negotiated between the sending and receiving servers. If they both support strong encryption (like AES 256), then that will be used. If not, a weaker grade of encryption may be used. The sending and receiving servers can choose the types of encryption they will support. If there is no overlap in what they support, then TLS will fail (this is rare).

What About Replies to Secure Messages?

Let’s say you send a message to someone that is securely delivered to their inbox over TLS. Then, that person replies to you. Will that reply be secure? This may be important if you are communicating sensitive information. The reply will use TLS only if:

  1. The recipient’s servers support TLS for outbound email (there is no way to test this externally).
  2. The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
  3. Both servers support overlapping TLS ciphers and protocols and can agree on a mutually acceptable means of encryption.

Unless familiar with the providers in question, it cannot be assumed that replies will use TLS. So, what should you do? Ultimately, it depends on what compliance standards you must meet, the level of risk you are willing to accept, and the types of communications you send. There are two general approaches to this question:

  1. Conservative. If replies must be secure in all cases, assuming TLS will be used is unreasonable. In this case, a more secure method should be used to encrypt the messages in transit and store them upon arrival. The recipient must log in to a secure portal to view the message and reply securely. Alternatively, PGP or S/MIME could be used for additional security.
  2. Aggressive. In some compliance situations like HIPAA, healthcare providers must ensure that ePHI is sent securely to patients. However, patients are not beholden to HIPAA and can send their information insecurely to anyone they want. If the patient’s reply is insecure, that could be okay. For these reasons, and because using TLS for email security is so easy, many do not worry about the security of email replies. However, this should be a risk factor you consider in an internal security audit. Consider nuanced policies that allow you to send less sensitive messages with TLS while sending more sensitive messages with higher security.

What are the Weaknesses of SMTP TLS?

As discussed, SMTP TLS has been around for a long time and has recently seen a great deal of adoption. However, it has some deficiencies compared to other types of email security:

  • There is no mandatory support for TLS in the email system.
  • A receiver’s support of the SMTP TLS option can be trivially removed by an active man-in-the-middle because TLS certificates are not actively verified.
  • Encryption is not used if any aspect of the TLS negotiation is undecipherable/garbled. It is very easy for a man-in-the-middle to inject garbage into the TLS handshake (which is done in clear text) and have the connection downgraded to plain text (opportunistic TLS) or have the connection fail (forced TLS).
  • Even when SMTP TLS is offered and accepted, the certificate presented during the TLS handshake is usually not checked to see if it is for the expected domain and unexpired. Most MTAs offer self-signed certificates as a pro forma. Thus, in many cases, one has an encrypted channel to an unauthenticated MTA, which can only prevent passive eavesdropping.

The Latest Updates to Secure SMTP TLS

Some solutions help remedy these issues—for example, SMTP Strict Transport Security. SMTP STS enables recipient servers to publish information about their SMTP TLS support in their DNS. This prevents man-in-the-middle downgrades to plain text delivery, ensures more robust TLS protocols are used, and can enable certificate validation.

In addition, users can adopt TLS 1.3. NIST recommends that government agencies develop migration plans to support TLS 1.3 by January 1, 2024. LuxSci supports both SMTP MTA-STS and TLS 1.3.

How Secure SMTP TLS Email Works with LuxSci

Inbound TLS

LuxSci’s inbound email servers support TLS for encrypted inbound email delivery from any sending email provider that also supports that. For selected organizations, LuxSci also locks down its servers to only accept email from them if delivered over TLS.

Outbound Opportunistic TLS

LuxSci’s outbound email servers will always use TLS with any server that claims to support it and with whom we can talk TLS v1.0+ using a strong cipher. The message will not be sent securely if the TLS connection to such a server fails (due to misconfiguration or no security protocols in common). Outbound opportunistic TLS encryption is automatic for all LuxSci customers, even those without SecureLine.

Forced TLS

When Forced TLS is enabled, the message is either dropped or sent with an alternate form of encryption if the recipient’s server does not support TLS. This ensures that messages will never be sent insecurely. Forced TLS is also in place for all LuxSci customers sending to banks and organizations that have requested that we globally enforce TLS to their servers.

Support for strong encryption

LuxSci’s servers will use the strongest encryption supported by the recipient’s email server. LuxSci servers will never employ an encryption cipher that uses less than 128 bits (they will fail to deliver rather than deliver via an excessively weak encryption cipher), and they will never use SSL v2 or SSL v3.

Does LuxSci Have Any Other Special TLS Features?

When using LuxSci SecureLine for outbound email encryption:

  1. SMTP MTA STS: LuxSci’s domains support SMTP MTA STS, and LuxSci’s SecureLine encryption system leverages STS information about recipient domains to improve connection security.
  2. Try TLS: Account administrators can have secure messages “try TLS first” and deliver that way. If TLS is unavailable, the messages would fall back and use more secure options like PGP, S/MIME, or Escrow. Email security is easy, seamless, and automatic when communicating internally or with others who support TLS.
  3. TLS Exclusive: This is a special LuxSci-exclusive TLS sending feature. TLS Exclusive is just like Forced TLS, except that messages that can’t connect over TLS are just dropped. This is ideal for low-importance emails that must still be compliant, like email marketing messages in healthcare. In such cases, the ease of use of TLS is more important than receiving the message.
  4. TLS Only Forwarding: Account administrators can restrict any server-side email forwarding settings in their accounts from allowing forwarding to any email addresses that do not support TLS for email delivery.
  5. Encryption Escalation: Often, TLS is suitable for most messages, but some messages need to be encrypted using something stronger. LuxSci allows users to escalate the encryption from TLS to Escrow with a click (in WebMail) or by entering particular text in the subject line (for messages sent from email programs like Outlook).
  6. Domain Monitoring: When TLS delivery is enabled for SecureLine accounts, messages will never be insecurely sent to domains that purport to be TLS-enabled, i.e., TLS delivery is enforced and no longer “opportunistic.” The system monitors these domains and updates their TLS-compliance status daily.
  7. Double Encryption: Messages sent using SecureLine and PGP or S/MIME will still use Opportunistic TLS whenever possible for message delivery. In these cases, messages are often “double encrypted.” First, they are encrypted with PGP or S/MIME and may be encrypted again during transport using TLS.
  8. No Weak TLS: Unlike many organizations, LuxSci’s TLS support for SMTP and other servers only supports those protocol levels (e.g., TLS v1.0+) and ciphers recommended by NIST for government communications and which are required for HIPAA. So, all communications with LuxSci servers will be over a compliant implementation of TLS.

For customers who can use TLS to meet security or compliance requirements, it enables seamless security and “use of email as usual.” SecureLine with Forced TLS enables clients to take advantage of this level of security whenever possible while automatically falling back to other methods when TLS is unavailable.

Of course, using Forced TLS as the sole method of encryption is optional; if your compliance needs are more substantial, you can turn off TLS-Only delivery or restrict it so that it is used only with specific recipients.

If your email use cases are complicated, LuxSci’s flexibility enables the secure sending of emails to any recipient, regardless of their email service provider’s support for TLS. Contact the LuxSci sales team to learn more about our secure SMTP TLS email sending.
