Email is a poor place for health information and an unavoidable part of running a health-tech company. Appointment reminders, account notices, clinician onboarding and partner conversations all happen in inboxes, and each one is a chance to put something sensitive where it doesn't belong.
This post is about everyday operational habits that reduce that risk. It isn't a compliance guide.
Read this first
This is not medical, legal or regulatory advice. Health data is regulated in most places, under rules such as HIPAA in the United States and GDPR in the European Union, among many others, and whether those rules apply to you depends on your business model, your customers and your contracts. If you handle regulated health data, you need advice from qualified counsel and email vendors that contractually commit to supporting your obligations. Koltrix holds no compliance certifications, and our data processing terms ask customers not to use the service for special categories of data, such as health data, in ways it isn't designed for. The habits below are useful for any team, but they don't make an email setup compliant on their own.
Habit 1: Treat email as a notification channel, not a records channel
The most effective privacy habit is structural: send people a notice that something exists, and show the substance inside your authenticated product.
| Instead of emailing… | Send… |
|---|---|
| Test results or clinical notes | "A new document is available in your account" with a sign-in link |
| A diagnosis or condition name | A neutral notice with no clinical detail |
| A full appointment summary | Date and time only, with details in the app |
| Medication or treatment names | A prompt to check the app |
| Attachments with health details | A link to view them after signing in |
This approach limits what's exposed if an email is forwarded, read over someone's shoulder, sent to an old address, or sits in a mailbox that's later compromised.
Habit 2: Write subject lines as if a stranger will read them
Subject lines show up on lock screens, in notification previews and in shared family devices. Assume they'll be seen by people other than the recipient.
- Avoid clinical terms in subjects and preview text. "Your appointment on May 12" is safer than naming the specialty.
- Mind the preview text. Most clients show the first line of the body next to the subject. Make that line generic too.
- Keep sender names neutral where it matters. A sender display name can reveal more than you intend, depending on your product's specialty. Think about what the name says on its own.
Habit 3: Keep your own team's email clean
Patient-facing templates get reviewed carefully. Internal email often doesn't. Some habits for the team:
- Don't paste patient details into internal email or chat. Refer to records by an internal identifier and keep the details in the system of record.
- Don't forward customer threads to personal accounts, even temporarily.
- Use shared mailboxes with per-person access for functions like support or clinician onboarding, so access can be granted and revoked individually and you know who can see what.
- Require two-factor authentication on every account that can read customer email.
- Review mailbox access regularly, especially after role changes and departures.
Habit 4: Be careful with partners and integrations
Health-tech companies often exchange mail with clinics, labs, insurers or other partners. A few practices help:
- Agree on channels in advance. If sensitive information has to be exchanged, decide with the partner which secure channel to use, rather than defaulting to email.
- Verify before acting on requests. Requests to change payment details or send records to a new address are classic social-engineering moves. Confirm through a known contact method.
- Limit automated email content from integrations. Notification emails generated by third-party tools may include more detail than you'd choose. Check their templates.
Habit 5: Make your email hard to impersonate
Patients and clinicians who trust your brand are attractive targets for phishing. Reduce the chance that someone can pose as you:
- Publish SPF, DKIM and DMARC, and move DMARC to an enforcing policy once you're sure all your legitimate senders pass. Our plain-English guide to the three records covers the basics.
- Never ask for passwords or codes by email, and say so in your templates.
- Send people to sign in themselves instead of clicking an email link to a login form when the request is sensitive.
- Keep a small, consistent set of sending addresses, so recipients learn what real messages look like.
Habit 6: Plan for wrong recipients
Misdirected email is one of the most common privacy incidents in any industry, health included. It usually comes from autocomplete picking the wrong contact or an outdated address on file.
- Verify email addresses at signup with a confirmation step.
- Let users update their address easily and confirm changes at both the old and new address.
- Turn on undo send or a short send delay for staff if your mail tool offers it.
- Know what to do when it happens. Write down who to tell internally and what steps to take. Your counsel can tell you whether notification obligations apply.
A sample appointment reminder
Here's what a privacy-conscious reminder can look like for a made-up telehealth product:
Subject: Reminder: your appointment on Tuesday, May 12
Hi Sam,
This is a reminder of your upcoming appointment on
Tuesday, May 12 at 10:30 a.m. (Eastern).
To see details or reschedule, sign in to your
Wellpath.example account.
We will never ask for your password by email.
Questions? Reply to this message during business hours.No specialty, no practitioner name, no reason for the visit. Everything else lives behind sign-in.
A short checklist for your templates
- No clinical details in subjects, preview text or bodies
- Notices point to authenticated pages instead of carrying data
- No attachments with health information
- Sender names reviewed for what they reveal
- "We will never ask for…" line included
- Address verification and change confirmation in place
- SPF, DKIM and DMARC published and checked
- Legal review of what your obligations actually are
Key takeaways
- Use email to notify, and keep health details behind authentication in your product.
- Write subjects and preview text for the stranger who might see a lock screen.
- Shared mailboxes with per-person access, two-factor authentication and no personal forwarding keep the team side tidy.
- These habits reduce risk, but they don't make a setup compliant. If you handle regulated health data, get qualified legal advice and use vendors that contractually support your obligations.
