How do I fix the reputation of my IP address?

Business Solutions, HIPAA Compliant Email

It happens — you’re sending email messages without issue, and then suddenly emails are not being delivered, or they’re being flagged as spam. A little digging reveals that the problem is that your “IP reputation” is poor, and you need to fix it somehow.

What is IP Reputation?

Email service providers (e.g. AOL, Gmail, LuxSci) and email filtering systems (e.g. Barracuda, McAfee, Proofpoint, SenderScore) collaborate on and track the sending of unwanted emails to reduce the blight of email spam that continues to plague the Internet. Some of the significant factors that they track include:

Quantity of email sent from your IP address
The spam-like characteristics of these messages (based on spam filter analysis)
The number of spam complaints by recipients of these messages
The number of messages sent to invalid recipients or honey pots. Honey pots are email addresses that do not belong to real people and are traps for senders who have acquired these email addresses via web site scraping or some other illegitimate manner.

Put together, these factors end up determining the reputation of that IP address with respect to the sending of email messages. If the reputation becomes poor, then spam filters will start to quarantine or reject your email messages, resulting in poor deliverability.

What is the “bad neighborhood” effect?

If your sending server is in the same neighborhood as other sending servers, then its reputation can be affected by the others’ actions. The following are some well-known “bad neighborhoods”:

Public cloud servers (e.g. at Amazon). As these servers can be owned by anyone, they are often used for sending unwanted emails. As a result, if you use one of these servers, your IP address probably has a diminished reputation.
Big Internet Service Providers (ISPs). ISPs like Comcast always have problems with suppressing spam coming from their users’ systems (due largely to malware infecting end users and sending unsolicited emails from unsuspecting people’s machines). If you are sending messages directly from your ISP, your reputation can fluctuate wildly as a function of your neighborhood.

If you are suffering from the bad neighborhood effect, your choices are limited and simple:

You can talk to your ISP about the problem, but they may not take any action.
Instead of sending emails directly from servers in this location, you need to relay the messages through a third-party email sending service with a good reputation. This service should also scrub your messages, removing all trace of the tarnished IP of origin.

What can I do to fix IP reputation?

Assuming that you are not a victim of a bad neighborhood, you can take steps to repair the reputation of your server’s IP address. The first thing you need to do is stop sending outbound emails until you take further steps. This can be frustrating, but it is better to send no email than to continue sending problematic email.

Resolving your server reputation problem will take some work. You need to make sure that you’re only sending legitimate emails to real people, as doing this for a while will establish a track record of good sending for your server.

Review Email Lists and Message Content

To fix your IP reputation, take a look at the types of emails you are sending and who is receiving them.

Content. Review the actual content of the messages that you are sending. Make sure that it doesn’t sound like spam. Some software systems can help you analyze your message content for “spamminess.”
CAN-SPAM. Make sure that any bulk email is compliant with CAN-SPAM. Your purpose for emailing, identity, and method for unsubscribing should all be clear.
Sending Rate. Make sure that your server is not sending messages too fast to places like AOL, Yahoo, Google, etc. Pushing too many too fast is a red flag and can hurt your reputation.
Real Addresses. Sending to old or invalid email addresses does significant harm to your IP reputation. You need to review bounced emails and remove dead-end addresses from your lists.
Good Addresses. The single most important thing that you can do for your IP reputation is to send to only people who actually want and expect your email messages. This means, in particular:
1. Do not use or send to purchased lists.
2. Discard addresses obtained through scraping web pages or copied from directories or books.
3. You must get rid of all spam-trap and honey pot email addresses that you may have accumulated.
4. Eliminate all addresses that have not subscribed to your messages or with whom you do not have an existing business relationship.
5. Remove the addresses of all people that have requested to be unsubscribed or otherwise eliminated from future mailings.
6. Remove the addresses of all people that have complained that your messages are spam.

Items 1-3 relate to your message content and sending pattern and are fairly easy to address. The rest of the issues involve actively cleaning and managing your recipient lists. You need to clean all of your existing lists and then manage them going forward.

How do I clean my lists?

Cleaning mailing lists can be difficult and expensive without getting into more trouble with your IP reputation. We recommend the following steps, in the order presented. Depending on your current situation, you might not have enough information to perform them all — that will just increase the cost of the last step.

First, contact your email service provider or IT staff and:

Find a list of all of your bouncebacks and remove them
Find a list of all spam complaints and remove these recipients

Then, take your lists to FreshAddress, and use their SafeToSend email address validation service. It will take your lists, sanitize them, and then provide you with new, improved, and cleaned lists. SafeToSend will:

Validate. Ensure that email addresses are well-formatted, correspond to valid domain names that accept email, and match a working email address.
Correct. The addresses are checked for common spelling errors and typos and corrected as needed (e.g. @gmail.com instead of @gamil.com).
Protect. SafeToSend will identify and remove: spam trap email addresses, role accounts, disposable domains, fictitious and malicious email addresses, and addresses on “do not email lists” and FCC wireless domains.

After sanitizing your lists with SafeToSend and after removing people who have not opted-in to email messages, your delivery rate will skyrocket and complaints will plummet.

How long does it take to improve my IP reputation?

Sending a solid stream of messages with appropriate content to your new, safe list will reestablish your server’s IP reputation. However, it could take a number of days or even weeks to rebuild your reputation. It will depend on how much good email you are sending after repairing your content and lists. Poor IP reputation will continue to affect your email delivery rates as you rebuild that reputation.

To improve email deliverability quickly, the only other option is to relay your email out through a third-party email sending provider and having them scrub your server’s IP address. It won’t rebuild your IP reputation, though the lack of email being sent from your server can slowly improve its reputation to normal levels. However, if your reputation is due to poor lists, third-party email providers will not want your business and may terminate your account if they detect your use of bad email lists.

How do I maintain my lists?

Going forward, you need to be actively collecting bounceback and failure messages and removing these recipient addresses from your lists. Additionally, you need to be collecting spam complaints via feedback loops from the major email service providers (i.e. AOL, Yahoo, etc.) and remove these complainer addresses as well.

If you do not have the facility to capture bounces and feedback, you should use an email sending service that can take care of this for you.

List maintenance is critical. Failing to maintain your list will cause your IP reputation to gradually decline until your sending issues return.

Here’s What HIPAA Compliant Email Salespeople Don’t Tell You

November 18, 2025
Pete Wermter

With email security threats continuously increasing in number and sophistication, as well as healthcare companies requiring secure solutions to communicate with patients and customers, the need for HIPAA compliant email solutions has never been greater.

However, when looking for the right secure email services provider (ESP), healthcare organizations run the risk of making inaccurate assumptions about HIPAA compliance via what they learn from prospective vendors. This is due to the tendency for sales materials for HIPAA compliant email services, such as web pages or promotional videos, to highlight the strengths of the platform, while downplaying a healthcare company’s own role and responsibilities in securing protected health information (PHI).

With this firmly in mind, here are six key things that HIPAA compliant email salespeople don’t tell you about securing communications and achieving compliance.

1. The Shared Responsibility Model

Firstly, HIPAA compliant email salespeople are unlikely to emphasize the idea of shared responsibility when it comes to data security. This is the idea that two entities that share access to data, e.g., a healthcare company and their ESP, have a shared responsibility to preserve the privacy of that data.

In reality, most sales pitches explain the benefits and features of the solution, as opposed to stressing that compliance truly depends on how it’s configured and used. Now, that’s not to say that a salesperson is trying to hide this fact, as they’ll probably allude to training and configuration requirements. But, they’ll be less likely to make light of this and, more broadly, how shared responsibility factors into compliance.

2. A BAA Doesn’t Automatically Make You HIPAA Compliant

A business associate agreement (BAA) is essential for HIPAA compliance, but signing one doesn’t automatically make you compliant. Your organization still has to use the email delivery solution in a way that aligns with HIPAA regulations, which involves proper configuration, training, oversight, and reporting.

The misconception among some healthcare companies that a BAA equals compliance may be perpetuated by the term “HIPAA compliant email services provider”. This could give some the impression that the vendor is fully HIPAA compliant and, subsequently, in signing a BAA with them, the use of their services is fully compliant.

But, it’s not that simple.

Simply signing a BAA obscures the real effort involved in achieving compliance. There’s no official HIPAA seal of approval, and HIPAA compliant means that the solution is capable of being configured for compliant use, which is a shared responsibility. HIPAA compliant email salespeople are unlikely to volunteer this nuance, especially if their email solution requires considerable configuration or has a steep learning curve to use it securely.

3. Not All Solutions or Features Are HIPAA Compliant

Another key detail often underplayed by vendor sales materials of HIPAA compliant email solutions is that some of their features, or even entire services, aren’t covered by their BAAs, so they can’t be used to handle PHI.

These tools are referred to as “out of scope” and may include tools capable of integration with the email service, such as analytics or AI capabilities, but they don’t possess the cyber risk mitigation measures that align with HIPAA regulations. Perhaps the main reason for this is that many mass-market email delivery solutions, such as Microsoft 365 or Google Workspace, are designed for companies across all sectors. Consequently, while they can be HIPAA compliant, they weren’t developed from the ground up with the stringent regulatory demands of the healthcare industry in mind.

4. Solutions Are Not HIPAA Compliant “Out of The Box”

HIPAA compliant email salespeople may suggest that compliance is built into their platform, and healthcare organizations can use it to transmit PHI straight away, but this isn’t the case. Healthcare companies must still configure the email platform accordingly, as per the security requirements determined by their risk assessment, e.g., applying the right level of encryption.

Also, if the email service is difficult to configure for HIPAA compliance or if the vendor’s configuration documentation lacks detail, that presents another obstacle to its compliant use.

In addition to configuration, healthcare companies also have to implement access management controls and policies, establishing the extent to which each employee can access PHI in respect to their roles and responsibilities. From there, they will have to train their workforce on how to use the HIPAA compliant email solution securely, which may include those tools that fall outside the scope of your BAA with the vendor, and must not be used for the disclosure of patient data.

5. Essential Security Features Cost Extra

Another more egregious version of an ESP not being HIPAA compliant out of the box is having features required for compliance, such as encryption or audit logging, as premium add-ons and not included in the solution’s base pricing.

A vendor’s sales materials for its email service might list the necessary safeguards, but underemphasize the fact that only some versions of their platform are truly HIPAA compliant. Consequently, healthcare companies must confirm that the features required for HIPAA compliant email communications are included in the plan they’re purchasing.

6. The Importance of Staff Training on HIPAA

HIPAA compliant email salespeople are often remiss in stressing the need for additional workforce training alongside the deployment of their platform. A healthcare company’s employees must be trained on how to securely use the email client, how to ID potential threats, and best practices for including PHI in email communications, as well as the regulations tied to HIPAA and data security.

This includes educating users on the differences between regular and secure email, and what they must do to safeguard patient and customer data. Fortunately, secure email solutions from providers like LuxSci enable automated email encryption, and users do not need to take any additional actions to ensure encryption when sending emails.

Additionally, in some cases, employees will need to be trained on which tools or features do not align with HIPAA guidelines and must not be used to process PHI.

What Does b2b Medical Marketing Help Healthcare Vendors Accomplish?

November 4, 2025
Erik Kangas

B2b medical marketing helps healthcare vendors to explain the practical value of a product to clinical and administrative buyers by presenting clear information that supports decision making across operational and regulatory domains. Buyers respond to communication that describes how a tool fits into routine workflows and how it handles information, and the process depends on steady explanations rather than promotional language.

Early Movement in the Buyer Relationship

The first stage of communication gives prospective buyers a clear sense of what the service does and why it belongs in their setting. Healthcare groups rely on predictable routines and they look for products that support those routines without creating unnecessary strain on staff. When an introduction explains how a tool fits into patient movement, documentation demands, or coordination between departments, readers can place the service into a familiar context. This lowers the cognitive effort required to evaluate whether further consideration is worthwhile and creates a smoother path for later discussions, which is why many vendors treat early stage explanations as the base of effective b2b medical marketing in this environment.

The Influence of Operational Structure

Clinical and administrative environments are shaped by long standing systems, varied software tools, and staff roles that have developed around known constraints. Vendors using b2b medical marketing describe how a product enters this environment so that the buyer can picture the transition from interest to adoption. Extended explanations of onboarding steps, data migration choices, and staff training routines help readers understand how daily operations shift when a new tool is introduced. These explanations allow decision makers to forecast workload changes rather than relying on assumptions, and they reflect the broader goal of b2b medical marketing which is to reduce uncertainty.

Regulatory Considerations in Vendor Communication

Healthcare buyers place great weight on regulatory matters, which is why clear descriptions of data handling are central to this type of communication. Readers look for information about access management, retention practices, audit preparation, and the path information takes through each component of a system. When vendors describe these areas in detail, compliance teams can perform early assessments and avoid long chains of clarification requests. This approach supports efficient internal review because the buyer gains confidence that the vendor maintains structured processes rather than improvised arrangements, and this clarity strengthens the overall impact of b2b medical marketing.

Reliability Expectations Within Clinical Settings

Healthcare settings cannot tolerate uncertainty in the systems that support patient care. B2b medical marketing provides insight into how a vendor manages service interruptions, planned updates, backup routines, and recovery efforts. A description of past events or internal procedures gives readers a sense of how the vendor behaves when conditions are difficult. Buyers place great value on this type of detail because it helps them differentiate between systems that hold up under stress and systems that falter when routine performance is disrupted, and these reliability discussions form a core thread in b2b medical marketing for clinical tools.

Perspectives That Influence Internal Decision Making

Each participant in the purchasing process evaluates a product through a different lens. Financial leaders consider long term spending patterns, clinical managers look for ease of use and effects on staff time, and compliance teams examine information practices. Communication that attends to these perspectives without shifting tone allows the reader to share information across departments with minimal friction. This prevents internal delays because each group can assess the service using information that relates to its role in the organisation, and thoughtful navigation of these viewpoints reinforces the strength of b2b medical marketing across healthcare markets.

The Role of Educational Content in Vendor Outreach

Healthcare groups respond well to educational material that speaks to challenges in clinical settings. Articles and guides that explain regulatory shifts, workflow bottlenecks, or mistakes observed in comparable organisations allow readers to examine their own processes. This form of communication helps buyers understand the vendor’s approach to problem solving and creates familiarity before any formal evaluation begins. Educational content performs well in this field because it demonstrates practical awareness rather than relying on abstract claims, making it a central component of many b2b medical marketing programs.

Use After Adoption

Decision makers frequently look beyond the moment of purchase and seek a clear view of the daily relationship that follows implementation. Communication describing staff support, update patterns, training formats, and communication channels helps buyers picture how the tool will fit into routine operations. Long paragraphs that describe the lived experience of using the service allow internal champions to advocate for the product with fewer unknowns, which supports faster movement through approval stages. This expectation of clarity after adoption aligns with the wider goals of b2b medical marketing which encourage predictable cooperation between vendor and buyer.

Documentation Supporting Review Processes

Healthcare organisations rely heavily on documentation during evaluation. Guides, records, administrative instructions, and explanations of data controls enable teams to examine the product without repeated requests for further detail. B2b medical marketing that introduces these documents early in the conversation reduces internal delays because reviewers can move through their procedures with all necessary information available at the outset. This transparent approach helps build trust between the vendor and the buyer and underscores the value of documentation as a recurring theme within b2b medical marketing.

B2b medical marketing works most effectively when vendors show an accurate grasp of clinical pressures and administrative realities. When communication reflects these conditions and acknowledges the challenges that healthcare groups experience during busy periods, readers gain confidence that the vendor understands the world they operate in. This supports deeper conversations about integration, performance, and long term cooperation across the organisation.

What is a HIPAA Email API?

June 25, 2025
Ian Snipper

A HIPAA email API is a programming interface that allows healthcare applications to send secure emails containing protected health information while maintaining compliance with HIPAA regulations. These APIs provide developers with tools to integrate encrypted email functionality into healthcare software systems while automatically handling security requirements, audit logging, and PHI protection measures. Healthcare software development increasingly requires email capabilities for patient notifications, care coordination, and administrative communications. Standard email APIs lack the security controls and compliance features necessary for healthcare applications that handle sensitive patient data.

Technical Architecture and Security Framework

REST and SOAP protocols provide the foundation for most HIPAA email APIs, enabling healthcare applications to integrate email functionality through standard web service interfaces. These protocols support secure authentication and encrypted data transmission while maintaining compatibility with diverse healthcare technology environments. Message queuing systems help manage email delivery during high-volume periods while maintaining security controls throughout the transmission process. Healthcare applications can submit emails to secure queues where they receive encryption and compliance validation before delivery to recipients. Error handling mechanisms ensure that failed email transmissions do not compromise PHI security or leave sensitive data exposed in log files. HIPAA email APIs must provide detailed error information to developers while protecting patient information from unauthorized disclosure.

Authentication and Authorization Protocols

API key management provides secure access control for healthcare applications using email services. These keys must include appropriate permissions and expiration policies that prevent unauthorized access while enabling legitimate healthcare communications, allowing healthcare applications to authenticate users and obtain appropriate permissions for sending emails on their behalf. These protocols help ensure that only authorized personnel can trigger email communications containing PHI.

LuxSci supports three industry-standard authentication methods—alongside its proprietary LuxSci Secure option. These include:

OAuth 2.0 – The modern standard. Secure, flexible, and ideal for enterprise-scale integrations.
API Key – Simple and efficient. Ideal for server-to-server use when convenience matters most.
Basic Authentication – Straightforward, widely supported. Good for internal systems and quick testing.

For those who want the tightest possible control over API sessions—including HMAC signatures and session revocation—LuxSci Secure authentication remains the best option for customers.

Message Formatting, Template Management, and Security

MIME and S/MIME encoding support enables healthcare applications to send rich-text emails with attachments while maintaining encryption and security controls. These capabilities allow inclusion of medical images, test results, and formatted reports within compliant email communications. Template engines help healthcare developers create standardized email formats that include dynamic patient data while preventing inappropriate PHI disclosure. These systems can validate content against organizational policies before message transmission. Attachment handling procedures ensure that medical documents and images receive appropriate encryption and access controls when included in email communications. HIPAA email APIs must provide secure upload and transmission capabilities for healthcare file attachments.

Delivery Tracking and Status Reporting

Real-time delivery status updates help healthcare applications track email transmission progress and identify potential delivery issues. These status reports must provide actionable information without exposing PHI to unauthorized systems or personnel. Read receipt capabilities enable healthcare applications to confirm that recipients have accessed important medical communications. These features help care coordination while maintaining appropriate privacy protections for patient email interactions. Bounce management systems handle failed email deliveries appropriately while protecting PHI from exposure through error messages or automated responses. Healthcare applications need visibility into delivery problems without compromising patient privacy.

Compliance Logging and Audit Features

Automated audit trails capture detailed information about all email activities initiated through HIPAA email APIs. These logs must include sender identification, recipient information, transmission timestamps, and delivery status while protecting actual message content from unauthorized access. Compliance reporting features help healthcare organizations track their email usage patterns and identify potential policy violations. These reports can highlight unusual sending volumes, unauthorized recipient addresses, or messages that might violate PHI handling policies. Data retention controls ensure that API logs and message metadata comply with healthcare record-keeping requirements while managing storage costs and system performance. Healthcare organizations can configure retention periods based on their regulatory and operational needs.

Integration Patterns for Healthcare Applications

Electronic health record system (EHR), customer data platform (CDP), and Revenue Capture Management (RCM) platform integrations can enable automatic email messages and notifications to be sent based on clinical events like lab result availability or appointment scheduling changes. These integrations must respect minimum necessary standards while providing timely patient communications. Workflow automation allows healthcare applications to trigger email sequences based on patient care milestones or administrative requirements, tailoring communications based on user actions taken with each email. For example, healthcare organizations might send automated email reminders about upcoming appointments or medication refills. Batch processing capabilities enable healthcare organizations to send large volumes of patient communications efficiently while maintaining security controls and HIPAA compliance. These features support activities like appointment reminders, wellness newsletters, or billing notifications that affect many patients simultaneously.

Performance Optimization and Scalability

Rate limiting controls help healthcare organizations manage email volumes while preventing abuse or accidental bulk sending that might violate patient communication policies and damage your IP reputation. These controls can be customized based on organizational needs and user roles. Caching mechanisms improve API performance by storing frequently used templates and configuration data while maintaining appropriate security controls. These optimizations help reduce response times for healthcare applications without compromising PHI protection. Load balancing systems ensure reliable email delivery during peak usage periods when healthcare organizations send high volumes of patient communications. These systems must maintain security controls while distributing processing loads across multiple servers.

Testing and Development Support

Sandbox environments enable healthcare developers to test email functionality without exposing real patient data or sending communications to actual patients. These testing systems provide realistic API responses while using protected data that supports thorough integration testing. Documentation and code samples help healthcare development teams implement HIPAA email API functionality correctly while understanding security requirements and compliance obligations. These resources should include examples for common healthcare use cases and integration scenarios.

Finally, support services provide healthcare developers with technical assistance and compliance guidance during implementation and ongoing operations. API providers should offer expertise in both technical integration and healthcare regulatory requirements to ensure successful deployments.

How Do Healthcare Organizations Choose the Right Secure Email Providers?

September 25, 2025
Erik Kangas

Healthcare organizations look at provider capabilities across security architecture, compliance certifications, integration options, support quality, and pricing structures to identify solutions that meet their operational requirements and regulatory obligationsSecure email providers offer platforms that encrypt communications, maintain audit trails, and ensure compliance with healthcare privacy regulations while delivering reliable message transmission and user-friendly interfaces. Healthcare organizations must evaluate provider capabilities across security architecture, compliance certifications, integration options, support quality, and pricing structures to identify solutions that meet their operational requirements and regulatory obligations. The selection process involves analyzing encryption standards, business associate agreement terms, scalability options, and vendor stability to ensure long-term partnership success.

Security Architecture and Encryption Standards

End-to-end encryption capabilities distinguish professional secure email providers from standard business email services by protecting message content throughout the entire communication lifecycle. Advanced Encryption Standard (AES) 256-bit encryption transforms patient information into unreadable code before transmission, ensuring that intercepted messages cannot reveal sensitive health data to unauthorized parties. Transport Layer Security protocols create secure tunnels between email servers, preventing message interception during transmission across public internet infrastructure while maintaining message integrity throughout delivery processes.

Authentication mechanisms verify sender and recipient identities through digital certificates and multi-factor verification systems that prevent unauthorized access to healthcare communications. Certificate-based authentication ensures that only verified healthcare providers and authorized recipients can access encrypted patient information sent through email channels. Two-factor authentication requirements add security layers by requiring users to provide secondary verification through mobile devices, hardware tokens, or biometric identification before accessing their secure email accounts.

Key management systems protect the encryption keys that safeguard patient information while ensuring that legitimate healthcare providers can access necessary communications without delays that might interfere with patient care activities. Secure key storage prevents unauthorized access to encryption keys while maintaining backup procedures that prevent data loss if primary key storage systems experience failures. Automatic key rotation schedules strengthen security by regularly updating encryption keys without requiring manual intervention from busy healthcare staff members. Message integrity controls detect attempts to modify email content during transmission and alert recipients when communications may have been compromised by malicious actors. Digital signatures provide mathematical proof that messages originated from legitimate healthcare sources and have not been altered during transmission processes. These verification mechanisms enable healthcare providers to trust that patient communications received through secure email providers maintain their original content and authenticity.

Compliance Certifications and Regulatory Requirements

HIPAA compliance capabilities form the foundation for evaluating secure email providers serving healthcare organizations, as these platforms must meet strict administrative, physical, and technical safeguards required under federal privacy regulations. Providers should demonstrate their compliance through comprehensive business associate agreements that specify exactly how they will protect patient information, what security measures they maintain, and detailed procedures for reporting security incidents to healthcare organizations. Documentation requirements include maintaining audit trails, conducting risk assessments, and providing compliance reporting that supports healthcare organizations during regulatory inspections.

SOC 2 Type II certifications demonstrate that secure email providers maintain appropriate controls for security, availability, processing integrity, confidentiality, and privacy of customer data throughout their operations. These independent audits verify that providers implement effective security controls and maintain them consistently over extended periods rather than just during initial certification assessments. Healthcare organizations should request recent audit reports and verify that certification scopes include all services they plan to use from potential providers.

HITRUST certification addresses healthcare-specific security requirements and indicates that secure email providers understand the compliance challenges healthcare organizations experience daily. This certification framework incorporates requirements from multiple regulatory standards including HIPAA, HITECH, and state privacy laws to provide comprehensive security validation for healthcare technology vendors. Providers with current HITRUST certification have demonstrated their ability to protect healthcare information according to industry-recognized standards and best practices. International compliance standards may be relevant for healthcare organizations operating across multiple countries or serving patients with diverse privacy expectations. General Data Protection Regulation compliance enables secure email providers to serve healthcare organizations with European operations or patients, while other regional privacy regulations may require specialized compliance capabilities. Healthcare organizations should verify that their chosen providers can meet all applicable regulatory requirements for their specific operational scope and patient populations.

Integration Capabilities and Workflow Enhancement

Electronic health record integration enables seamless communication workflows by connecting secure email platforms with clinical documentation systems that healthcare providers use daily. API connectivity allows patient communications to populate appropriate sections of electronic health records automatically, eliminating duplicate data entry while ensuring comprehensive documentation of all patient interactions. Real-time synchronization ensures that email communications appear in patient records immediately, supporting clinical decision-making with complete communication histories.

Mobile device support enables healthcare providers to access secure communications from smartphones and tablets without compromising security standards or patient privacy protections. Native mobile applications should maintain the same encryption and authentication requirements as desktop platforms while providing convenient access for busy healthcare providers working from various locations. Cross-platform compatibility ensures that healthcare teams can communicate effectively regardless of their preferred devices or operating systems. Patient portal connections create unified communication platforms that give patients convenient access to their healthcare information through single sign-on interfaces. These integrated systems allow patients to receive test results, communicate with their care teams, and access educational resources through platforms that maintain consistent security standards across all communication channels. Unified patient experiences improve satisfaction while reducing technical support requirements for healthcare organizations managing multiple communication systems.

Vendor Stability and Support Quality

Financial stability assessments help healthcare organizations evaluate whether potential secure email providers can maintain service quality and security standards throughout long-term contract periods. Publicly available financial information, funding sources, and growth trajectories provide insights into provider stability and their ability to invest in security improvements and feature development. Healthcare organizations should avoid providers experiencing financial difficulties that might compromise service reliability or security investments during contract periods.

Customer support capabilities directly impact healthcare organization productivity when email issues arise during patient care activities or compliance requirements need immediate attention. Twenty-four hour support availability ensures that healthcare providers can resolve email problems quickly when patient communications are at risk or system outages threaten operational continuity. Dedicated healthcare support teams understand industry-specific requirements and can provide specialized assistance with compliance questions and workflow optimization challenges.

Implementation support quality determines how smoothly healthcare organizations can transition to new secure email providers without disrupting patient care activities or compromising security standards. Professional services teams should provide data migration assistance, system configuration guidance, and staff training programs that minimize transition disruption. Experienced implementation teams understand healthcare workflow requirements and can customize deployment approaches to accommodate operational constraints and compliance obligations.

Update and maintenance procedures ensure that secure email providers maintain current security standards and feature capabilities without requiring manual intervention from healthcare IT staff. Automatic security updates protect against emerging threats while maintaining email system availability during critical patient care periods. Scheduled maintenance windows should accommodate healthcare operation schedules and include advance notification procedures that allow organizations to plan around potential service interruptions from their secure email providers.

Pricing Models and Total Cost Considerations

Per-user pricing structures allow healthcare organizations to scale email costs directly with their workforce size while maintaining predictable budget planning capabilities. Volume discounts for larger organizations can reduce per-user costs substantially, making secure email more affordable for health systems and large practices with hundreds or thousands of users. Healthcare organizations should evaluate pricing tiers carefully to identify optimal user count thresholds that maximize cost efficiency while accommodating anticipated growth patterns.

Storage allocation policies affect long-term costs for healthcare organizations that must retain email communications for extended periods to meet regulatory and legal requirements. Unlimited storage plans provide cost predictability and eliminate concerns about archive capacity limits, while metered storage options may offer lower initial costs but create potential budget overruns if retention requirements exceed initial estimates. Healthcare organizations should calculate their long-term storage needs based on communication volume patterns and regulatory retention requirements.

Feature-based pricing allows organizations to customize their secure email investments by paying only for capabilities they actually need rather than comprehensive packages that include unused functionality. Basic encryption and compliance features constitute entry-level costs, while advanced capabilities like data loss prevention, integration APIs, and custom reporting may require supplementary charges. Healthcare organizations should evaluate feature requirements carefully to avoid both overpaying for unused capabilities and underestimating needs that require costly upgrades later.

Implementation costs include data migration services, system configuration assistance, and staff training programs that enable successful deployment of new secure email platforms. Professional services charges may range from thousands to tens of thousands of dollars depending on data volume, customization requirements, and integration complexity. Healthcare organizations should budget for these one-time expenses while evaluating total cost of ownership across expected contract periods with secure email providers, rather than focusing solely on recurring subscription fees.

Evaluation Criteria and Selection Process

Security assessment procedures should evaluate encryption strength, authentication mechanisms, access controls, and audit logging capabilities that secure email providers implement to protect healthcare communications. Penetration testing results, vulnerability assessments, and security certifications provide objective evidence of provider security capabilities. Healthcare organizations should request detailed security documentation and verify that provider security measures meet or exceed their internal requirements and regulatory obligations.

Compliance verification involves reviewing business associate agreements, audit reports, and compliance certifications to ensure that potential providers can meet healthcare privacy requirements effectively. Legal teams should evaluate contract terms, liability allocation, and incident response procedures to protect healthcare organizations from regulatory penalties or security breaches. Due diligence processes should include reference checks with current healthcare customers and verification of provider compliance track records.

Pilot testing enables healthcare organizations to evaluate secure email provider functionality, performance, and user experience before committing to long-term contracts or organization-wide implementations. Limited pilot programs with small user groups can identify potential issues with workflow integration, security controls, or usability that might affect broader deployments. Testing periods should include realistic usage scenarios and stress testing to verify that providers can handle anticipated communication volumes and user loads.

Vendor comparison matrices help healthcare organizations systematically evaluate multiple secure email providers across security, compliance, integration, support, and pricing criteria that matter most for their specific requirements. Weighted scoring systems can prioritize evaluation criteria based on organizational priorities and constraints. Comprehensive evaluations should include total cost of ownership calculations, implementation timeline estimates, and risk assessments that account for vendor stability and long-term viability considerations.

HIPAA-Compliant Email Marketing: FAQ

November 21, 2023
LuxSci

Email is an essential channel for most marketers. However, HIPAA regulations raise many questions for healthcare marketers who need to execute email marketing campaigns without violating patient privacy.

HIPAA is a complicated law that offers a lot of guidance but does not require the use of any specific technologies to protect patient privacy. The ambiguity causes a lot of confusion for marketers trying to integrate email into their marketing strategy. This article addresses some frequently asked questions about HIPAA-compliant email marketing and offers advice for securing patient data and futureproofing your marketing.

Do generic practice newsletters need to be protected?

Some marketers assume practice newsletters do not contain health information and, therefore, do not fall under HIPAA requirements. However, this assumption is often incorrect. Many are surprised to learn that protected health information can be implied from seemingly benign information.

In this way, many generic email newsletters often indirectly contain PHI because they are sent to lists of current patients. Email addresses are individually identifiable and combined with the email content; it may imply that they are patients of the practice. For example, say you send a “generic” newsletter to the patients of a dialysis clinic. An eavesdropper may be able to infer that the recipients receive dialysis. Therefore, the email reveals information about an individual’s health treatment, is PHI, and should be secured in compliance with HIPAA regulations.

In some cases, it can be complicated to determine what is PHI and what is not. Using a HIPAA-compliant marketing solution is best to avoid ambiguity and ensure security.

How Do I Find a HIPAA Compliant Email Marketing Vendor?

Unfortunately, using broadly popular email marketing platforms is not recommended. Many of these platforms were designed for e-commerce businesses and are not secure enough to meet HIPAA requirements. We do not recommend using a solution not specifically equipped to meet the healthcare industry’s unique security and compliance needs. To determine if your email marketing provider is compliant, they must meet three broad criteria at a minimum.

The vendor must sign a Business Associate Agreement outlining how they plan to secure your data and what they will do in the event of a breach.
Encrypt data at rest when it is stored in their systems.
Encrypt email messages and data in transit as it is sent to the recipients.

Not all vendors will be up to the task. Carefully vet your email marketing vendors to ensure they are taking steps to secure data and protect patient privacy.

What is an Email API?

API is an acronym that stands for “Application Programming Interface.” An email API gives applications (like CRMs, CDPs, or EHRs) the ability to send emails using data from the application. Email APIs also return campaign data to the platform or dashboards so you can assess the effectiveness of your marketing efforts. Trigger-based transactional or marketing emails are ideal for sending with an email API. In this situation, emails are sent when pre-determined conditions in the application are met. Healthcare organizations may use email APIs to send appointment reminders using electronic health records system data about a patient’s upcoming appointment.

Email APIs enable the automation of common email workflows. However, they are not interchangeable with email marketing platforms. Email APIs do not include the contact management systems standard in most email marketing platforms because all that data lives within the application they connect to. In addition, email API tools typically do not include drag-and-drop editor tools or other design features that help your emails stand out.

Does HIPAA permit providers to send unencrypted emails with PHI to patients?

Encryption is an addressable standard under the HIPAA Security Rule, but that does not mean it is optional. The HIPAA Privacy Rule does not explicitly forbid unencrypted email. Still, it does state that “other safeguards should be applied to protect privacy reasonably, such as limiting the amount or type of information disclosed through the unencrypted email.”

In addition, the Department of Health and Human Services also states that “covered entities are permitted to send individuals unencrypted emails if they have advised the individual of the risk, and the individual still prefers the unencrypted email.” Some organizations use waivers to inform patients of the risks and acquire permission to send unencrypted emails.

However, we do not recommend this approach for several reasons:

Keeping track of waivers over time and recording status changes and updates is challenging.
Signed waivers do not insulate you from the consequences of a HIPAA breach.
And finally, using waivers to send unencrypted emails doesn’t eliminate your other HIPAA obligations like data retention and disposal. Using a HIPAA-compliant solution is more manageable and eliminates ambiguity.

Can patients exercise their right of access by receiving PHI via unencrypted email?

Yes, but they must be fully informed of the risks and sign waivers acknowledging them. The caveats in the previous answer apply. It’s always better to utilize an encryption tool to protect patient data.

Is Microsoft 365 or Exchange 365 encryption sufficient for marketing emails?

Microsoft 365 can be configured with Office Message Encryption (OME) to comply with HIPAA. However, the program is not well-suited to HIPAA email marketing. OME primarily relies on portal pickup encryption, in which the message is stored securely on a server and requires the recipient to log in to the portal to read the email. If you are a marketer trying to increase engagement, the portal adds a barrier to access that many will not cross. Light-PHI marketing messages are best sent using TLS encryption. TLS-encrypted messages arrive in the recipient’s inbox just like a regular email and do not require a user to log in to read the message.

In addition, Microsoft 365 is not configured to send high volumes of email. If you plan to send large marketing campaigns, you could unintentionally disrupt regular business communications by sending all the messages through the same infrastructure. You should separate your business and marketing email sending to protect your IP reputation and achieve your desired sending throughput.

What are common email marketing use cases for healthcare?

Email marketing in healthcare is not restricted to boring practice newsletters. When you utilize tools that enable the use of PHI in your targeting and personalization efforts, the sky is the limit. With consumer preferences shifting toward digital communications, marketers willing to utilize the email channel and tactics like segmentation and personalization can see better results.

Email is an excellent way to communicate with patients. A sampling of ways that healthcare marketers can use email include:

engaging patients in their healthcare journey
educating patients about their healthcare conditions and treatments
improving attendance and scheduling
retaining patients
increasing preventative procedures
collecting data on the patient experience
improving patient satisfaction

Conclusion

HIPAA can be difficult to understand, but choosing the right tools and adequately vetting your vendors makes it easy to execute HIPAA-compliant email marketing campaigns. If you are interested in learning more about LuxSci’s easy-to-use, Secure Marketing platform, please contact our sales team.

How to Secure SMTP Email Delivery with TLS

August 29, 2023
LuxSci

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:

Computer A connects to Computer B (no security)
Computer B says “Hello” (no security)
Computer A says, “Let’s talk securely over TLS” (no security)
Computers A and B agree on how to do this (secure)
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:

purchase SSL certificates
configure the email servers to use them (and keep these configurations updated)
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:

No TLS: never use it.
Opportunistic TLS: use it if available; if not, send it insecurely.
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:

The recipient’s servers support TLS for outbound email (there is no way to test this externally).
The mail servers (where the “From” or “Reply” email address is hosted) support TLS for inbound email.
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:

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.
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:

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.
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.
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.
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.
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).
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.
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.
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.
