If your business works with personal health information, a basic email service isn't enough. You need a HIPAA compliant email provider that meets strict federal requirements for privacy, security, and data protection.

I’ve worked with the Cybernews research team to investigate the top options available. I’ve analyzed what these providers promise, how they secure sensitive data, and whether they’re a realistic fit for businesses that need to stay compliant. In this article, I’ll break down the best HIPAA compliant email services to help you make a confident, informed choice.

Our top 5 recommended HIPAA compliant email services

What is HIPAA compliant?

Let's start with the basics. HIPAA stands for the Health Insurance Portability and Accountability Act. It's a US law that regulates how health information should be kept private and secure. So, a service is HIPAA compliant when it meets the specific security standards the law requires.

In addition to protecting your inbox with a password or a basic spam filter, a HIPAA compliant email provider needs to secure Protected Health Information (PHI) in a legally sound way. These include encryption, access controls, audit logs, the ability to sign a Business Associate Agreement (BAA), and deep protections held under HIPAA scrutiny.

If you're working with anyone's medical data, even one mistake, like sending an unencrypted email to the wrong person, can count as a HIPAA violation. And that can mean heavy fines. People trust you with incredibly personal information. Using a HIPAA compliant email service provider is one way to prove you take that seriously.

Here's a checklist of what a HIPAA compliant email provider should offer:

• End-to-end encryption. Data must be unreadable in transit and at rest. If it's not encrypted, it's not protected
• Two-factor authentication (2FA). One password is not enough. A second verification step is a must
• User access control. You need to be able to manage who sees what information and when
• Audit logging. This is a way to track who accessed information and their actions
• Session timeout or auto-logoff. If your employer forgets to log out, the system should log off itself
• Secure archiving. Emails should be stored long-term, but still kept safe and retrievable
• Business Associate Agreement (BAA). This isn’t optional. If the provider won’t sign one, walk away
• Data loss prevention. This will help avoid accidental leaks, like sending protected health information to the wrong recipient

Best HIPAA-compliant email services providers – detailed list

After digging deep into provider documentation, user feedback, independent reviews, and the legal fine print, I’ve narrowed down to the most reliable and truly HIPAA compliant email services available today. If you’re comparing options, these are the ones worth paying close attention to.

1. Proton Mail – best for end-to-end encryption

🔐 End-to-end encryption:	OpenPGP-based encryption
📄 BAA provided:	✅ Yes
🛠️ Admin controls:	MFA only
🧱 Zero-access architecture:	✅ Yes

Visit Proton Mail

Proton Mail is a Switzerland-based email provider built with privacy at its core. It offers robust end-to-end encryption and a zero-access design, meaning not even Proton can read your emails. That's important for HIPAA compliance.

Since the company is based in Switzerland and is known for its strict data protection law, your information is also legally protected from most outside access, including government surveillance.

Best for

• Clinics or solo practices that want maximum data privacy without relying on US-based services
• Organizations concerned about government surveillance or legal access to patient communications
• Healthcare teams that don't need deep Electronic Health Record integrations but prioritize secure and confidential messaging.

Pricing and plans

Proton Mail offers several plans, but for HIPAA use, you'll need at least the Mail Essentials or Business plan to access custom domains and the Business Associate Agreement (BAA). Pricing starts at $6.99/user/month and scales with storage and user needs.

2. Paubox – best for large healthcare organizations

🔐 End-to-end encryption:	No-portal TLS encryption
📄 BAA provided:	✅ Yes
🛠️ Admin controls:	Role-based access
🧱 Zero-access architecture:	❌ No

Visit Paubox

Paubox is a US based provider that focuses entirely on HIPAA-compliant communication. Unlike many secure email solutions that rely on portals or extra logins, Paubox encryption integrates directly within your existing inbox, like Google Workspace or Microsoft 365. It's also HITRUST CSF Certified, which indicates a high level of trustworthiness when it comes to meeting HIPAA's technical and administrative safeguards in the Health industry.

Best for

• Healthcare providers who want zero disruption to existing workflows
• Organizations using Gmail or Outlook that need full compliance without retraining staff
• Teams that need to send HIPAA-compliant forms or secure large attachments up to 50MB

Pricing and plans

Pricing starts at $29/month per user for the Standard plan. Higher tiers like Plus and Premium have advanced features like inbound security and executive protection. All plans include end-to-end encryption and come with a Business Associate Agreement (BAA).

3. LuxSci – best for secure file storage

🔐 End-to-end encryption:	Optional SecureLine
📄 BAA provided:	✅ Yes
🛠️ Admin controls:	Granular permissions
🧱 Zero-access architecture:	❌ No

Visit LuxSci

LuxSci is one of the most configurable HIPAA compliant email providers. It's built for healthcare providers who need real control over how their secure communication works. You can choose from multiple encryption methods based on who you're emailing.

One thing I appreciated during my research was how much they emphasize customization. You don't just sign up and hope it fits. You actually speak with their team and build out what your organization needs. That's a good sign, especially for larger groups with more complicated workflows.

Best for

• Mid-size to large healthcare providers with advanced compliance needs
• Teams that require customizable encryption settings for different communication scenarios
• Organizations that want thorough logging, backup, and expert onboarding

Pricing and plans

LuxSci doesn't offer flat-rate pricing on its website. Instead, they structure plans around your needs, like storage, user count, encryption preferences, and so on. It takes a conversation with their team to get a quote, which might feel like an extra step, but it also means you're not paying for features you won't use.

4. Virtru – best for Google and Microsoft workspace integration

🔐 End-to-end encryption:	Client-side AES encryption
📄 BAA provided:	✅ Yes
🛠️ Admin controls:	Access expiration tools
🧱 Zero-access architecture:	❌ No

Visit Virtru

Virtru is a strong contender in the HIPAA compliant email space, especially for teams already using Google Workspace or Microsoft 365. With Virtru, your data is secured before it even leaves your device, which adds extra protection for sensitive health information.

Moreover, recipients don't need to create accounts to access your information. They get a secure link that opens messages in Virtru's encrypted reader. That matters because one of the biggest roadblocks to HIPAA email compliance is getting the recipient side to cooperate. Virtru removes that friction without compromising security.

Best for

• Healthcare providers using Gmail or Outlook who want a simpler way to stay HIPAA compliant
• Teams that share sensitive documents regularly with patients or partners
• Organizations that need both email and file encryption under one platform

Pricing and plans

Virtru's pricing starts at $119 per month, which includes support for five users. This base package offers essential email data protection features designed for small businesses. More advanced capabilities, like Data Loss Prevention, granular access control, and audit reporting, are available in higher-tier plans.

5. Hushmail – best for medical professionals

🔐 End-to-end encryption:	Encrypted forms/messages
📄 BAA provided:	✅ Yes
🛠️ Admin controls:	Basic admin tools
🧱 Zero-access architecture:	❌ No

Visit Hushmail

Hushmail has been around for a long time, and its Hushmail for Healthcare plan is specifically tailored for HIPAA compliant email. It brings together encrypted email, secure forms, and built-in e-signature functionality.

With features, you can manage patient consent, intake forms, and communications all within one secure system. They also sign a Business Associate Agreement (BAA) with healthcare clients, which is essential for legal and HIPAA compliance.

Best for

• Small to mid-size clinics that want a unified solution for email, forms, and signatures
• Businesses that prefer a single vendor rather than stitching together multiple tools
• Healthcare teams focused on compliance but did not need deep integrations.

Pricing and plans

For the Healthcare plan, Hushmail charges $11.99 per user per month, which includes email encryption, secure web forms, and e-signature tools, all under a HIPAA-compliant framework.

How we chose best HIPAA compliant email service providers

To make sure the HIPAA-compliant email provider recommendations are accurate and genuinely useful, the Cybernews team and I evaluated each service across six essential criteria. Every candidate was scored on a 100-point scale distributed across the following weighted categories:

• Security and encryption (35%). I prioritized providers that offer strong technical protections like end-to-end encryption, TLS 1.2 or higher, and AES-256 at-rest security.
• HIPAA specific compliance (25%). I focused on whether each provider offers a Business Associate Agreement (BAA), along with features like audit logging, breach notifications, and built-in tools to reduce the risk of exposing PHI..
• Features and functionality (15%). I looked at how well each service supports practical organization needs like access control, mobile use, integration with EHR platforms, and secure form or portal options.
• Ease of use and administration (10%). I considered how easy the platform is to navigate, how intuitive the admin controls are, and whether it supports users without adding unnecessary complexity.
• Pricing and total cost of ownership (10%). I reviewed the cost per user, the presence of hidden fees, scalability for larger teams, and whether free tiers or trials are available for testing before full commitment.
• Support and reputation (5%). I looked at each provider’s track record for reliability, support responsiveness, and what actual users are saying in forums, reviews, and case studies.

Final thoughts

Any organization that handles protected health information needs a HIPAA compliant email service – one that fits smoothly into existing workflows without disruption.

During my review, Proton Mail stood out as the best HIPAA compliant email service due to its strong emphasis on privacy and simplicity. It uses zero-access encryption, meaning even the provider can’t read your messages.. Proton Mail operates under Switzerland's strict privacy laws, which limit government and third-party access to user data. It is especially useful for organizations that don't need complex integration but care deeply about confidentiality. However, teams that rely on Gmail or Outlook or need secure forms might find providers like Paubox and LuxSci more suitable.

There's no universal HIPAA compliant email service that fits every business case. What matters most is choosing an email service that aligns with your organization's workflow, risk profile, and communication habits.
