Creating secure web forms starts with creating a secure website. This process is more complex than creating web pages and adding an SSL Certificate. A certificate is a solid first step, but it only goes so far as to protect whatever sensitive data necessitates security in the first place.

Naive attempts at security can ultimately make the data less secure and more likely to be compromised by creating an appetizing target for the unscrupulous.

So, what do you do beyond hiring a developer with significant security expertise? Start with this article. Its purpose is to shed light on many of the most significant factors in creating secure web forms and how to address them. At a minimum, reading this article will help you intelligently discuss website security with the developers you hire.

What Is Involved In Creating Secure Web Forms?

If you want to add a secure web form to your website, first, you must understand how to securely configure the website. Website security is a serious and complex topic; this article only discusses the high points. Check out some of our other articles and eBooks for more detailed information on website security.

Here are some of the critical issues that need to be considered:

  1. SSL – Is the website and form secured to transmit data from the end user safely? Is your website form page protected with SSL to prevent tampering with its contents?
  2. Web page content – Is the HTML content sent to the end-user protected from Cross-Site Scripting (XSS) issues, and does it avoid loading objects insecurely or from third parties?
  3. Script Security – Are the scripts or programs that process the submitted data written with security in mind? Do they have any vulnerabilities?
  4. Infrastructure – Is the website hosting provider trusted and known for good security? Are you on a shared server when you should be on a dedicated one?
  5. Data Flows – What do you do with the data once submitted? Is that data secured?
  6. Tracking – Do you track events such as data access and submission?
  7. Archival and Backup – Are there processes to make backups and permanent archives of important data?

SSL – Web Security Starts Here

SSL certificates are required for creating a secure website and form. The SSL certificate allows:

  1. The encryption of data sent to and from your web server and users to prevent eavesdropping or tampering.
  2. Your users trust that they are connecting to your website securely.

An SSL certificates on a properly configured web server encrypts your website data as it flows to and from your end users.

To get an SSL certificate, you can order one directly from a third party, or your web hosting provider will handle it for you. In either case, the web host will need to install the certificate on the server where the website is hosted, and then you will need to make changes to your site to take full advantage of the secure channel you have added.

SSL and Encryption

The most significant reason people use SSL is to encrypt the data transmitted from their website and the end-user. When an end-user visits a page protected by SSL, their web browser communicates over a secure channel with the web server so that all data transmitted is sent over this encrypted channel. This helps prevent eavesdropping and man-in-the-middle attacks on the data (more on these below).

Without SSL encryption, there is little or no protection of the data.

SSL and Trust

The most overlooked and misunderstood aspect of SSL is the establishment of trust. That is, enabling your end-users to trust and feel confident that they are connecting to your website. What else could they be connecting to, you may ask?

  1. Someone with access to the network between the end-user and website could be trying to intercept and read all the web traffic or altering your website pages themselves (e.g., changing your forms to submit the data to them instead of you). This is called a man-in-the-middle attack. Even with SSL security, a man-in-the-middle can present the end-user with an SSL Certificate for your domain name that looks legitimate, like a forged ID card.
  2. The user could be visiting another website that is pretending to be yours. This phishing website could collect information from your users for malicious purposes. Unless your users identify this site as illegitimate, they could be duped into revealing personal information. How could they end up at a phishing website like this? This can happen by clicking on a link emailed to them or by visiting a misspelled version of your URL. No site is immune from such attacks, but you can work to mitigate them.

SSL Certificates and Cybersecurity

As mentioned above, SSL certificates are not the sole website and form security solution, but they can help! To understand how it’s worth looking at how certificates are awarded. SSL certificates are signed by a third-party authority, the “Certificate Authority.” This can be:

  1. You, if you sign your certificates.
  2. A respected third-party issuing:
    1. A cheap or free certificate validating only your domain.
    2. A more expensive “Extended Validation” certificate which also validates your organization.

If you sign your own certificates, your website will generate warnings when anyone visits it. Users can choose to dismiss them, but more commonly, they will be more likely to navigate away from the website. For this reason, self-signed certificates are never recommended for a public website. Self-signed certificates provide no inherent trust that they are legitimate (anyone can generate one and pose as your site). They look amateurish and are annoying to the end user. Self-signed certificates should only be used in internal or test environments.

When ordering a certificate from a trusted third-party authority, there are various types that you can order. The cheapest ones are called domain-validated certificates. These work by emailing your domain administrator a validation link. Once verified, the certificate is awarded. These domain-validated certificates are acceptable and provide excellent security; however, as no humans are directly involved in the validation process, it may be easier for an attacker to get an illegitimate certificate by gaining control of the admin’s inbox or via other methods.

You can also order Extended Validation certificates. They cost more because real people validate the organization and your domain ownership. They make phone calls and ensure that everything looks right. If you have one of these certificates, your browser’s address bar turns green (or displays a lock symbol) when visitors come there to indicate that this site is trusted. If you want to maximize trust and make it easy for your end-users to identify your site as legitimate, you should use an Extended Validation certificate. These cost more but are well worth it in terms of security and trust. If EV certificates are outside your budget, you should still use an SSL certificate from some trusted third party.

Securing Web Forms with SSL

Once your website has an SSL certificate installed by a web host, your web pages can be accessed with addresses that start with “https://” instead of just “http://.” The “s” in “https” means “secure.” Note:

  1. When connected to a web page using a secure address like “https://yourdomain.com,” the web browser will show a lock icon to inform you that the connection is secure.
  2. Web pages that end in “.shtml” are not necessarily secure. The “s” means “server” (i.e., server-parsed page) and not “secure.” So, for example, “http://yourdomain.com/index.shtml” is not a secure page, but “https://yourdomain.com/index.html” is a secure page.
  3. With SSL enabled, you can access the same page securely and insecurely in many default web server configurations. Both “http://yourdomain.com/form.html” and “https://yourdomain.com/form.html” work and show the form — the only difference is the use of SSL or not.

So, let’s say that you have a web form located at “http://yourdomain.com/form.html.” You have an SSL certificate, and your web host has installed it. Next, you want to:

  1. Make sure people connect securely to the form page.
  2. Make sure that no one can connect to the form page insecurely.

These two goals might sound the same, but they are not.

Enforce Secure Connections to Form Pages

Since regular website pages may be insecure, you need to ensure that the links to the secure form page are absolute links starting with the prefix “https://.” This will ensure that anyone clicking these links will be taken to the form page on a secure connection.

The best solution is to use an HSTS (HTTP Strict Transport Security), which tells browsers that they should always use the secure version of your website. If you choose to have both the insecure (http) and secure (https) versions of your site running at the same time (not recommended), then you need to be careful with linking so that sensitive pages are secured:

Wrong Links: Relative links are not recommended because, if the user is on an insecure page, relative links will always take them to insecure versions of the destination page. So relative links like the following should be avoided:

Fill out my form!

Correct Links: Absolute links will ensure a secure connection by specifying that SSL must be used via the link prefix “https://.”

For example: <a href=”https://yourdomain.com/form.html”>Fill out my form!

Be sure that all links to all secure pages of the site use this secure format with the “https://” prefix.

Side Note: These days, it is recommended that you use SSL for all website pages, not just ones that process sensitive information. This is good for user trust, security, and privacy. It is also good for Search Engine Optimization (as Google will reward you for securing your site). If you set up your site so all pages are always secure, relative links are safe.

Ensure No One Can Connect to Form Pages Insecurely

Using the above suggestions, all the links on your website will take users to the secure version of the form. However, most web hosts leave the insecure version of the form there, and users can still access it if they enter the insecure address directly (or if links are directed to the insecure page). As a next step, you should ensure that accessing the form page via an insecure connection is impossible.

There are several different ways that this can be done. Some of these include:

Separate space for SSL pages: If your web host has this feature, you can configure the website to store web pages for secure (SSL) connections in a different directory from those for insecure pages. If this feature is enabled, the form page is placed in the secure directory and no copies are in the insecure directory. Thus, any insecure requests for these pages would result in a “page not found” error. You could then implement server-side redirection rules where if someone requests the insecure page, they are automatically redirected to the secure version (this can be done using .htaccess files and the “Redirect” directive). If you did this, secure and insecure requests for the page would take the user to the secure version with no errors, warnings, or issues for the end user.

Scripted pages: If the form page is generated by a server-side script (i.e., PHP, Perl, Python, or JAVA), then the script itself can determine if the request is secure or not (e.g., by looking at the server environment variables). For secure requests, it can render the form as usual. The user receives an error for insecure requests or is redirected to the proper secure location. 

Securing all pages: (Recommended) The site can be configured to automatically redirect all requests for insecure pages to the respective secure page. All pages will be secure, and any accidental/incorrect requests for the insecure pages will still get people to the right place. Security is greatly improved if you have set this up.

If my form is posted to a secure form processing script, why does it need to be secured?

This question is usually asked when a third-party manages the form processing. Is securing the form itself with SSL needed?

The answer is based on the following facts:

  1. The data sent from end-users to the server will be secure and encrypted during transmission. This is critical for creating secure websites and forms that require HIPAA compliance.
  2. Non-technical end-users will only know if their data is securely submitted once it is done. Many end-users will refrain from submitting sensitive data to an insecure form on your site.
  3. End-users cannot know if they are viewing your website or a phishing site or if eavesdropping and modification are happening. Many users will not trust the connection and will not want to submit their data through your site if it appears insecure.
  4. If your form page is insecure, it is straightforward for any malicious party to perform a man-in-the-middle attack to eavesdrop on connections, modify your form in transit to change what is collected and where the data is sent, and set up phishing sites. Your end-users can’t tell if this is going on.

If you do not secure your web form with SSL, it is vulnerable to attack. If nothing is going on, you can rely on transmission security. However, that minimal level of security is not recommended for production websites or anywhere that compliance is required.

Other Aspects of Creating Secure Web Forms

Proper use of SSL for encryption and trust is only part of creating secure website forms. You must be concerned with many other aspects to protect your users, your application, and your company’s reputation. These include (but are not limited to):

1. Cross-Site Scripting (XSS). Suppose you include dynamic content on your web pages (i.e., information submitted by other users or content submitted via form fields), and that content is not cleaned of JavaScript and HTML. In that case, bad actors could make arbitrary content appear on your website, capture user data, or worse. All data displayed should be clear of undesirable content (script tags, special characters, HTML, and other things). This is one of the most significant security issues with dynamic web pages across the internet.

2. Secure Server-Side Programming: The scripts and programs that accept and process the data from online forms must be created with security in mind. They must validate all submitted data as needed without making assumptions about its format and content. The scripts must not provide avenues for attacks like SQL Injection. Scripts must not use submitted content as actual filenames or URLs for remote loading content. They should log any strange errors or problems for later analysis. They should provide a mechanism for blocking undesirable actions or users from using the scripts.

3. Validation: Validation of all input data is part of the above two points. However, it is so essential that we will repeat it and go over some of the fundamental points:

  • If you validate submitted content, always perform your validation on the server side. Even if you use JavaScript to validate the data on the client side, you should always re-validate it on the server side. Why? Because people can get around JavaScript and submit arbitrary content directly to your scripts. The scripts should be prepared to handle that.
  • Always de-taint submitted data. What does that mean? It means never trust submitted data and take pains to ensure that the submitted data matches what you expect. For example, if you have a select list that sends your script a number as the value, do not assume you are getting a number. Instead, check that it is a numeric value or convert whatever is submitted into a number.
  • Remove disallowed content from the text submitted by users. Remove or block special characters, embedded codes, and other things that should not be there.
  • Ensure the submitted data is manageable enough to be used.
  • Do not assume anything — program defensively.

4. Preserving State with Hidden Form Fields or Cookies: If your program remembers information from one page to another by saving the data in hidden form fields, then your program must also ensure that the content of those fields was not tampered with. One good way to do this is to make a hash of all the data, together with a secret value, and include that hash in the form data. Then, when the form is submitted, you can recompute the hash and compare it with what passed from the form. If they match, you are okay; if they do not, the data has been tampered with. No one can break this scheme without knowing your secret value or breaking your hashing algorithm. This method can also be used to validate data saved in cookies. You can go further and use time stamps to prevent replay attacks.

5. Third-Party Applications: If you install programs from third parties on your website, you must ensure there are no known security issues with these programs, and you must be sure to update these programs as soon as new versions are released. If you let your website languish with an older, vulnerable version of a program, it will become a target for hackers as they constantly search the internet for such websites. Your site will likely be hacked in these cases, possibly causing loss of business, deactivation of your website, and tarnishing your website’s reputation. Using a third-party application is easy, but you need to select a good one that places the burden of keeping it updated on you. An exception is using a third-party application hosted by the third party itself. In these cases, the third party ensures that the program is continuously updated with anything needed to address any security issues. The burden is on them and not you. If you choose a good, respectable vendor, you should have no problems.

All these things, and more, are critical to developing a secure web application.

Securing the Form Data After Submission

Ensuring that users’ data is transmitted securely to your web server is critical, as is ensuring that your application is secure and will not be hacked. To secure sensitive data, you must understand what happens to that data after your program receives it. Many people forget that transmitting the data from the web server may require just as much preparation as receiving it from their users in the first place.

In the following subsections, we will look at three different ways of saving and retrieving your users’ data. In each case, we will explain what is needed to secure the data in your systems.

Send Form Data via Email 

The most common action data processing scripts do is email the submitted data to the website owner’s email address. The website owner knows when there are new submissions by checking their email and can access the data immediately. Most people running websites check their email reasonably often, which integrates well with their business operations.

However, the standard ways of sending emails are entirely insecure. So, how can you use email while ensuring the data is secure and viewable only by the intended recipient?

  1. Have your website script encrypt the data.
  2. Send this encrypted data (or a link to download the encrypted data) to the intended viewers via regular email.

As the form data is encrypted within the email message, most insecurities inherent in email are obviated. You can also use secure third-party services to have your form data emailed to you securely without programming anything yourself.

Save the Submission in a Database

Many website owners like to save the submitted form data in a database (even if it is also emailed to someone). Why?

  1. The data is saved online and potentially accessible from anywhere.
  2. If the emailed copies of the data are lost, the copies in the database are still there.
  3. The database can be accessed through a web browser with a suitable user interface.
  4. The data is typically backed up and can be restored.

If storage in an online database is for you, then you need to:

  1. Use encryption, like SSL or PGP, to ensure the data is securely stored in the database. Why? The contents of database tables are not encrypted or secure in general. Storing unencrypted data makes it available to anyone with access to the database or its backups.
  2. Provide a user interface that allows you to access the database data. It must be secure, have robust access controls, and provide a means for decrypting the data.

The database option requires much work to make a secure and usable solution. For this reason, most small organizations do not end up using secure database storage for important form data.

Save the Data in Files

The file storage option is the “quick and dirty” alternative to secure database storage. Essentially, your program will:

  1. Make a file containing the form data.
  2. Encrypt that file using PGP or SSL.
  3. Save that encrypted file in a directory on the web server that is not accessible from the website. Another option is to save it in an online file-sharing service.

Then, the website owners can log in to the web server using Secure FTP and download these files as needed. They can be decrypted locally when the data must be accessed. Other simpler data access mechanisms are available if the files are saved in an online file share.

This solution is secure and provides an excellent backup to securely emailed data.

Other Technical Tips for Creating Secure Website Forms

There are many other considerations in developing and maintaining a secure website and forms. It would be impossible to cover or even list them all. However, here are some more interesting and valuable tips.

Use Secure Cookies

If your secure site uses cookies for anything, set the “secure” cookie and the “httpOnly” flags. This will ensure that these cookies are never sent insecurely over the internet when the visitor arrives at any insecure pages of your website (they are not sent at all to insecure pages) and thus helps preserve the security of the contents of these secure cookies.

Prevent Form Spam

Form spam occurs when automated programs find your web forms and try to send spam through them. Form spam can result in hundreds or thousands of useless form posts daily. Once you start getting form spam, stopping it is a priority. There are two primary ways to help prevent spam:

  1. CAPTCHA – This method requires end-users to read text embedded in an image and type that text successfully into a form field. The back-end program then validates this. Since most spam programs cannot read text embedded in images, it will successfully block almost all automated forms spam. However, CAPTCHA requires the users to perform one more step, which can be annoying.
  2. JavaScript and Cookies – Most automated form spam programs do not process JavaScript or use cookies. If your web form requires JavaScript to submit the form successfully, bots cannot do this, and most form spam will be blocked. This method is less reliable than CAPTCHA but does not require any extra work from the end-user. Note that if you wish to use the JavaScript method, you must be sure that arbitrary submissions to the default action URL of your forms will never succeed—only submissions made after the execution of your custom JavaScript should succeed.

Minimize the Need for Trust

A good rule of thumb is to minimize the need to trust third parties and trust only the trustworthy.

  1. If you do not trust your internal IT staff, do not host your web application on your servers or give them access to the server used.
  2. If you do not trust the third-party hosting your website, encrypt the form data as soon as possible. This helps ensure that the data is not saved anywhere in plain text and is not backed up in plain text, thus minimizing your exposure to unauthorized people. Further, ensure that the private keys and passwords needed to decrypt the data are not stored on the web host’s servers.
  3. Ensure that only authorized staff can access the submitted form data. Ideally, it should always be encrypted, and only authorized people should be able to decrypt it.

These are just a few obvious points. As you evaluate your web application and data flow, ask yourself, “Who can access the raw data and how?” at each stage. Are there stages where you are trusting people who should not be trusted?

Forced use of strong encryption in SSL

The strength of encryption used by SSL is a function of both the user’s web browser and the server. Even if your web server supports excellent encryption, like AES256, the user’s browser may choose a weaker level of encryption. Older versions of Internet Explorer are notable for choosing weaker encryption in the interest of speed.

You can modify your web server configuration so that only levels of encryption you approve can be used to access your site.

Use Two-Factor Authentication

Two-factor authentication is standard on very secure sites now. You require a password and something else (a code or token) to validate their identity. With both, the user can log in. Avoid using only SMS texting as the second factor, which is no longer considered secure.

HIPAA Compliant Email

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

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 Are HIPAA Email Rules?

HIPAA email rules are regulatory standards established by the Department of Health and Human Services that govern how healthcare organizations handle protected health information through electronic messaging systems. These rules include privacy standards for PHI disclosure, security standards for electronic data protection, and breach notification standards for incident reporting when email communications involve unauthorized access or disclosure. Healthcare providers often struggle to understand which specific HIPAA email rules apply to their email communications and how to implement compliance measures effectively. Clear understanding of regulatory requirements helps organizations develop appropriate policies while avoiding costly violations and maintaining patient trust.

Privacy Standards for Email Communications

Use and disclosure limitations restrict how healthcare organizations can share PHI through email without patient authorization. These standards permit email communications for treatment, payment, and healthcare operations while requiring authorization for marketing, research, and other purposes. Individual control provisions give patients rights to restrict email disclosures, access email records about themselves, and request corrections to inaccurate information shared electronically. Healthcare organizations must provide clear procedures for patients to exercise these rights. Minimum necessary standards require healthcare organizations to limit email disclosures to only the PHI needed for the intended purpose. Complete medical records should not be shared via email unless the entire record is necessary for the specific communication.

Security Standards for Electronic Information Systems

Access control requirements mandate that healthcare organizations implement procedures to verify user identity before allowing access to email systems containing PHI. These procedures must include unique user identification, emergency access procedures, and automatic logoff capabilities. Audit control standards require healthcare organizations to implement hardware, software, and procedural mechanisms that record and examine access to email systems containing PHI. These controls must capture user identification, access attempts, and system activities. Integrity protections ensure that PHI transmitted through email is not improperly altered or destroyed. Healthcare organizations must implement measures to detect unauthorized changes to email content and maintain data accuracy throughout transmission and storage.

Transmission Security Requirements

Encryption implementation helps protect PHI during email transmission between healthcare organizations and external recipients. While not explicitly required, encryption serves as a reasonable protection when risk assessments indicate potential vulnerabilities in email communications. Network controls protect email infrastructure from unauthorized access and cyber threats. These controls include firewalls, intrusion detection systems, and secure network configurations that prevent attackers from intercepting email communications containing PHI. End-to-end protection measures ensure that PHI remains secure throughout the entire email communication process from sender to recipient. Healthcare organizations must evaluate their email systems to ensure adequate protection during all phases of message handling.

HIPAA Email Rules & Breach Notification Standards

Incident assessment rules require healthcare organizations to evaluate email security incidents within 60 days to determine whether they constitute breaches requiring notification. These assessments must consider the nature of PHI involved, unauthorized recipients, and actual or potential harm. Patient notification requirements mandate that healthcare organizations inform affected individuals about email breaches within 60 days of discovery. Notifications must include specific details about the breach, types of information involved, and recommendations for protective actions. Media notification obligations apply when email breaches affect 500 or more individuals in the same state or jurisdiction. Healthcare organizations must provide press releases or other media notifications to warn the public about significant breaches.

Administrative Requirements for Compliance Programs

Policy development standards require healthcare organizations to create written procedures governing email usage, PHI protection, and incident response. These policies must address all applicable HIPAA email rules and provide clear guidance for workforce members. Training obligations mandate that healthcare organizations educate workforce members about HIPAA email rules and their responsibilities for PHI protection. Training must be provided to all personnel with access to email systems and updated regularly to address new requirements.

Officer designation requirements mandate that healthcare organizations appoint privacy and security officers responsible for developing and implementing email compliance programs. These individuals must have appropriate authority and expertise to ensure regulatory compliance.

Business Associate Requirements

Contract obligations require healthcare organizations to execute business associate agreements with email service providers that access PHI. These agreements must include specific provisions about PHI protection, breach notification, and compliance monitoring.Oversight responsibilities require healthcare organizations to monitor business associate compliance with HIPAA email rules through audits, security assessments, and performance reviews. Organizations cannot rely solely on contracts without verifying actual compliance. Liability allocation between healthcare organizations and business associates depends on their respective roles in PHI protection and which party controls specific aspects of email security. Clear contractual provisions help define responsibility for different compliance obligations.

Enforcement and Penalty Provisions

Investigation procedures allow the Office for Civil Rights to review healthcare organization email practices and system configurations during compliance reviews. These investigations can include on-site visits, document reviews, and interviews with personnel. Penalty structure establishes monetary sanctions for violations of HIPAA email rules, based on factors like culpability level, violation severity, and organizational size. Penalties range from thousands to millions of dollars depending on these factors and previous compliance history. Corrective action authority allows OCR to require specific changes to email policies, training programs, or system configurations to address identified deficiencies. These requirements often include ongoing monitoring and reporting obligations.

Implementation Guidance and Best Practices

Risk assessment procedures help healthcare organizations evaluate their email systems and identify potential vulnerabilities requiring additional protections. These assessments should consider technology capabilities, usage patterns, and potential threats to PHI security. Documentation requirements ensure that healthcare organizations maintain records demonstrating compliance with HIPAA email rules including policies, training records, and incident reports. These documents support audit preparation and demonstrate good faith compliance efforts. Performance monitoring helps healthcare organizations track their compliance with email rules and identify areas needing improvement. Regular assessments should review policy effectiveness, training adequacy, and incident response capabilities.

searching for an email

How Can I Prove an Email was Sent to Me?

Almost everyone has been in this situation: someone claims to have sent you an email message, but you look in your inbox and don’t see it. As far as you know, you never got it. How can you prove an email was sent?

searching for an email

How to Prove That an Email was Sent

So, where do you start? As the purported recipient of an email message, the easiest way to prove that a message was sent to you is to have a copy of that message. It could be:

  1. In your inbox or another email folder
  2. A copy in your permanent email archives

 Sometimes, missing emails are caused by simple user errors. The obvious place to start the search is in your inbox and email folders. It’s also a good idea to check your email filtering and archival services. It’s possible that your email filtering system accidentally flagged the message as spam or sent it to quarantine. If it’s not there, check your email archival system. That should capture a copy of all sent and received messages. 

Hopefully, that will solve the issue. If it doesn’t, it’s worth stepping back to understand where the email could have gone and where you should turn next to solve the problem.

What happened to the email?

In reality, there are only a few things that could have happened:

  1. The recipient never sent the message.
  2. The recipient did send the message, but it did not reach you.
  3. The message did make it to you, but it was accidentally or inadvertently deleted (or overlooked).

Let’s begin with what you can check and investigate. Start your search soon. The more time that elapses, the less evidence you may have, as logs and backups get deleted over time.

Did the recipient actually send the message?

First, you should know that the sender could have put tracking on the message so that they were informed if you opened or read it (even if you are unaware of the tracking). In such cases, the sender can disprove false claims of “I didn’t get it!” If you are concerned about an email being ignored, use read recipients or tracking pixels to confirm email delivery.  

If you never saw the message, do what we discussed above and start searching your email folders for it. It could have been accidentally moved to the wrong folder or sent to the Trash folder. If you have a folder that keeps copies of all inbound emails (like LuxSci’s “BACKUP” folder), check there too. Check your spam folder and spam-filtering system. Your spam-filtering system may also have logs that you can search for evidence of this message passing through it. Finally, check any custom email filters you may have set up with your email service provider or in your email programs. If you have filters that auto-delete or auto-reject some messages, see if that may have happened to the message in question.

The searches above are straightforward; you can do many of them yourself. Often, they will yield evidence of the missing message or explain why you might not have received it.

Maybe the email was sent but didn’t make it to you?

Email messages leave a trail as they travel from the sender to the recipient. This trail is visible in the “Received” email headers of the message (if you have it) and in the server logs at the sender’s email provider and your email provider. If you know some aspects of the message in question (i.e., the subject, sender, recipient, and date/time sent), you can ask your email service provider to search their logs to see if there is any evidence of such a message arriving in their systems. This will tell you if such a message reached your email provider. However, email providers can typically only search the most recent one to two weeks of logs. So, if the message in question was from a while ago, your email service provider may be unable to help you (or may charge you a lot of money to manually extract and search archived log files if they have them). 

If your email provider has no record of the message or cannot search their logs, you (or the sender) can ask the same question of the sender’s email provider. If they can provide records of such an email being sent through their system, that will prove the email was sent.

The log file analysis provided by the email providers could also explain why you didn’t get the message. Your email address might have been spelled wrong, there could have been a server glitch or issue, etc. However, if the message was sent long ago, the chance of learning anything useful from the email provider is small. Also, if you use a commodity email provider such as AOL, Yahoo, Outlook, Gmail, etc., you may find it impossible to contact a technical support person and have them perform an accurate and helpful log search. Premium providers, like LuxSci, are more likely to support your requests. 

The last thing you can do is have the sender review their sent email folders for a copy of that message. If they have it, that can indicate that they sent it and can reveal why you didn’t get it (i.e., wrong email address, content that would have triggered your filters, etc.). However, be wary. It is easy to forge a message in a sent email folder, so it should not be considered definitive proof that the message was sent. And, even so, just because the message was sent, it does not prove it ever made it to your email provider or inbox.

The recipient never actually sent the email message

If the sending event was recent, then the data from your email service provider can prove that the message did not reach you, but that doesn’t prove that it was not sent. The sender may claim that they do not have a record of sent messages and that their email provider will not do log searching, and that may also be true. At this point, you are stuck without a resolution. 

While email is a reliable delivery system, there are many ways for messages not to make it to the intended recipient. Whether it was not sent or was sent and never arrived, the result is the same- no message for you. As a result, it’s best not to send legal notices or other important documents only by email. Using read receipts and other technologies when sending important messages can help increase confidence that an email was sent and received. Still, there is no foolproof way to guarantee email delivery.

How Do I Prove the Email Sender’s Identity?

A separate but related question is, how can I be sure the sender is who they say they are? Social engineering is rising, and cybercriminals can use technology to impersonate individuals and companies. If you are questioning whether the sender actually sent the message to your inbox (or if it is from a spammer or cybercriminal), it is necessary to perform a forensic analysis of the email headers (particularly the Received lines, DKIM signatures, etc.) and possibly get the sender’s email provider involved to corroborate the evidence. To learn more about how to conduct this analysis, please read: How Spammers and Hackers Can Send Forged Email.

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.

What You Need To Know About Email Deliverability

Email deliverability refers to the ability of emails to reach recipients’ inboxes successfully without being filtered into spam folders or blocked entirely by email service providers. This metric encompasses the entire journey an email takes from sender to recipient, including authentication protocols, sender reputation, content quality, and recipient engagement patterns. For healthcare organizations managing patient communications, provider networks, and supplier relationships, understanding email deliverability becomes particularly important given the sensitive nature of healthcare data and the need for reliable communication channels. Healthcare providers, payers, and suppliers who master email deliverability can maintain better patient relationships, reduce administrative costs, and avoid compliance issues that arise from failed communications.

How Email Service Providers Evaluate Messages

Email service providers use algorithms to evaluate incoming messages and determine their appropriate destination within recipient email systems. These systems analyze multiple factors simultaneously, including sender authentication records, message content, sending patterns, and recipient behavior. The filtering process occurs in real-time, with providers like Gmail, Outlook, and Yahoo applying machine learning models trained on billions of email interactions to identify potential spam or malicious content.

Authentication plays a large role in this filtering process through verification of sender identity. Providers verify sender identity through SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting, and Conformance) records. Healthcare organizations without properly configured authentication often find their appointment reminders, lab results, or billing communications relegated to spam folders, disrupting patient care workflows and administrative processes.

Content analysis represents another layer of filtering, where providers examine subject lines, message body text, and embedded links for spam indicators. Healthcare communications containing medical terminology, prescription information, or insurance details may trigger false positives if not properly formatted or if sent from domains with poor reputation scores. The complexity of these filtering systems means that even legitimate healthcare communications can face delivery challenges without proper optimization.

Recipient engagement metrics influence future email deliverability for healthcare organizations, as providers track open rates, click-through rates, and spam complaint rates. When patients consistently ignore or delete emails from healthcare organizations, providers may begin filtering future messages more aggressively. This creates a feedback loop where poor engagement leads to worse delivery rates, making it increasingly difficult to reach patients with important medical information.

Sender Reputation and Healthcare Communications

Sender reputation functions as a digital credit score for email domains and IP addresses, influencing whether healthcare organizations can reliably reach patients, providers, and business partners. Email service providers maintain reputation databases that track sending behavior, bounce rates, spam complaints, and recipient engagement over time. A single domain or IP address with poor reputation can affect email deliverability across an entire healthcare network, creating widespread communication problems.

Healthcare organizations face unique reputation challenges due to the nature of their communications and patient populations. Patient appointment reminders sent to outdated email addresses generate high bounce rates, while automated billing notifications may receive spam complaints from recipients who forgot they subscribed to such communications. These factors can gradually erode sender reputation, making it increasingly difficult to reach patients with time-sensitive medical information or coordinate care between providers.

The healthcare industry’s regulatory environment adds complexity to reputation management, as organizations must balance effective communication with privacy requirements. HIPAA compliance considerations may limit how organizations can personalize emails or track recipient behavior, potentially affecting engagement metrics that influence sender reputation. Healthcare organizations tackle these constraints while maintaining the communication effectiveness needed for patient care and business operations.

Reputation recovery in healthcare settings requires sustained effort and careful monitoring of multiple factors. Organizations must implement proper list hygiene practices, authenticate their domains correctly, and monitor feedback loops from major email providers. The process can take weeks or months, during which patient communications may continue experiencing delivery issues that could impact care coordination and administrative efficiency. Proactive reputation management helps prevent these problems before they affect patient care.

Authentication Protocols for Healthcare Email Security

Modern email deliverability depends heavily on proper implementation of authentication protocols that verify sender identity and prevent email spoofing attempts. SPF records specify which mail servers are authorized to send emails on behalf of a domain, while DKIM adds cryptographic signatures to verify message integrity. DMARC ties these protocols together by instructing receiving servers how to handle emails that fail authentication checks, providing policy guidance for email providers.

Healthcare organizations must configure these protocols carefully to avoid authentication failures that could block legitimate patient communications. A misconfigured SPF record might prevent appointment confirmation emails from reaching patients, while improper DKIM setup could cause lab result notifications to be filtered as spam. These authentication failures can have serious implications for patient care, particularly when dealing with urgent medical communications or time-sensitive treatment instructions.

The implementation process requires coordination between IT teams, email service providers, and third-party healthcare applications that send email on behalf of the organization. Many healthcare systems use multiple platforms for patient communications, billing, and administrative functions, each requiring proper authentication configuration to maintain good email deliverability across all communication channels. This complexity makes authentication management an important component of healthcare IT operations.

Regular monitoring and maintenance of authentication protocols helps ensure continued email deliverability for healthcare organizations. DNS records can change unexpectedly, third-party applications may modify their sending practices, and email providers periodically update their authentication requirements. Healthcare organizations benefit from establishing procedures for ongoing authentication monitoring and having technical expertise available to address configuration issues quickly when they arise.

Content Quality and Compliance Considerations

Email content quality directly affects deliverability, with providers using advanced algorithms to evaluate message structure, language patterns, and formatting for spam indicators. Healthcare organizations must balance informative content with delivery requirements, ensuring that medical communications reach their intended recipients without triggering spam filters. This balance is challenging when dealing with complex medical terminology, prescription information, or insurance-related content that may resemble spam to automated filtering systems.

HIPAA compliance adds another layer of complexity to healthcare email content, as organizations must protect patient information while maintaining effective communication channels. Emails containing protected health information require additional security measures and careful content formatting to avoid both compliance violations and deliverability issues. The challenge is in creating compliant, informative communications that also pass through increasingly sophisticated spam filters without compromising patient privacy or care quality.

Subject line optimization also plays a role in healthcare email deliverability, as providers analyze these elements for spam indicators and patient engagement patterns. Generic subject lines like “Appointment Reminder” or “Lab Results Available” may perform differently across various email providers, requiring healthcare organizations to test and optimize their messaging strategies while maintaining compliance with healthcare communication regulations. Personalization can improve engagement but must be balanced with privacy requirements and spam filter sensitivities.

Message formatting and design elements influence both deliverability and patient engagement with healthcare communications. HTML emails with excessive images, complex layouts, or suspicious formatting may trigger spam filters, while plain text messages may not engage recipients effectively. Healthcare organizations must find the right balance between visual appeal and delivery reliability, often requiring testing across multiple email clients and providers to ensure consistent performance.

List Management and Patient Engagement Strategies

Effective list management forms the foundation of sustainable email deliverability for healthcare organizations managing communications with patients, providers, and suppliers. Clean, engaged recipient lists generate better delivery rates and help maintain positive sender reputation over time. Healthcare organizations must implement systematic approaches to list hygiene, including regular removal of bounced email addresses, management of unsubscribe requests, and monitoring of engagement patterns across different communication types.

Patient engagement patterns in healthcare differ significantly from typical marketing communications, as medical emails often contain information that recipients need rather than want. Appointment reminders, lab results, and billing notifications serve functional purposes that may not generate traditional engagement metrics like high open rates or click-through rates. Understanding these patterns helps healthcare organizations optimize their sending strategies without compromising the informational value of their communications or patient care quality.

Segmentation strategies in healthcare email deliverability focus on communication types and recipient preferences rather than demographic targeting approaches. Patients may engage differently with preventive care reminders compared to urgent test results, requiring sending approaches that consider both deliverability factors and patient communication preferences. This segmentation helps maintain good sender reputation while ensuring that different types of healthcare communications reach their intended recipients effectively.

Data quality management includes verification of patient contact information, preference management, and communication history tracking. Healthcare organizations benefit from implementing processes to capture updated email addresses during patient visits, verify contact information through multiple channels, and maintain records of communication preferences that respect patient choices while supporting care coordination needs. These practices improve both deliverability and patient satisfaction with healthcare communications.

Maintaining Email Deliverability Performance

Monitoring of email deliverability metrics provides healthcare organizations with the data needed to identify and address communication issues before they impact patient care or administrative operations. Key metrics include delivery rates, bounce rates, spam complaint rates, and inbox placement percentages across different email providers. These metrics help organizations understand how their communications perform across various platforms and identify potential problems with specific communication types or recipient segments.

Healthcare organizations should establish monitoring systems that track deliverability performance across different communication channels, including patient portal notifications, appointment reminders, billing communications, and provider-to-provider messages. This approach helps identify patterns that might indicate authentication issues, content problems, or reputation concerns that could affect the organization’s ability to communicate effectively with patients and business partners. Regular analysis of these patterns enables proactive problem-solving and continuous improvement.

Deliverability testing and optimization require ongoing attention to changing email provider policies, spam filter updates, and evolving patient communication preferences. Healthcare organizations benefit from implementing A/B testing for subject lines, send times, and content formats while maintaining compliance with healthcare regulations. Testing should include evaluation of deliverability performance across different email clients, devices, and providers to ensure consistent communication effectiveness.

Regular deliverability audits should include testing of authentication protocols, review of sender reputation scores, analysis of content performance, and evaluation of list management practices. These audits help healthcare organizations maintain optimal email deliverability while ensuring that their communication strategies remain aligned with both technical requirements and healthcare industry best practices for patient communication and data protection. Documentation of audit results and remediation activities shows commitment to maintaining reliable patient communications and regulatory compliance.
