Why Email Still Works in Healthcare
Email marketing has been declared obsolete so many times over the past two decades that physicians who have never invested in it could be forgiven for assuming they have not missed much. The declaration has consistently proven premature. Email remains one of the highest-return communication channels available to any business — and for medical practices, it offers specific advantages that newer channels cannot replicate.
The most important of these is the nature of the relationship. A patient who has given your practice their email address has already crossed the most significant threshold in healthcare marketing: they have become a patient. They know who you are. They have experienced your care. They have a reason to pay attention when you reach out — something that cannot be said of a prospective patient who sees your ad for the first time on a search results page or a social media feed.
Email reaches this established audience directly, without competing for attention in an algorithm-driven feed, without paying for each impression, and without the visibility limitations that affect organic social media posts. A well-maintained patient email list is one of the most durable marketing assets a practice can build — one that retains its value regardless of changes to search algorithms, advertising platform policies, or social media reach.
The challenge in healthcare is that email communication with patients operates under compliance requirements that general email marketing guidance does not address. Understanding those requirements is a prerequisite for using email effectively — not an obstacle to doing so.
The HIPAA Dimension
Email communication between a medical practice and its patients involves Protected Health Information whenever the content of the communication relates to the patient's health status, treatment, or appointment history. A reminder that a patient is due for an annual physical, a follow-up message referencing a recent visit, or a communication that addresses a patient's specific health situation all involve PHI — and HIPAA governs how that information can be transmitted.
Standard email is not a HIPAA-compliant communication channel by default. Emails transmitted through general commercial platforms without appropriate safeguards may be intercepted, stored insecurely, or accessed by parties outside the intended communication. HIPAA requires that electronic communications containing PHI be protected by reasonable safeguards — which in practice means using a platform that offers encryption, access controls, and audit logging appropriate to a healthcare environment.
Any email platform used to send communications that contain PHI must sign a Business Associate Agreement with the practice. This requirement extends to marketing-focused email platforms as well as clinical communication tools. A practice that uses Mailchimp to send appointment reminders or health-related newsletters — and Mailchimp explicitly does not sign BAAs and is not suitable for healthcare use involving PHI — is operating outside HIPAA requirements regardless of how benign the intent behind the communication.
The practical implication is that practices need to make a deliberate distinction between communications that involve PHI and those that do not — and ensure that the platform used for each type of communication is appropriate to its content.
Two Categories of Practice Email
Separating practice email into two distinct categories makes the compliance question more manageable and the strategic question clearer.
The first category is clinical and operational communication — appointment reminders, post-visit follow-ups, care instructions, lab result notifications, and similar messages that are specific to an individual patient's health situation. These communications involve PHI and require a HIPAA-compliant platform with a signed BAA. They are not marketing in the traditional sense; they are patient care and practice operations. Many EHR systems include patient communication functionality that handles this category appropriately. Standalone platforms like Klara, Spruce Health, and similar healthcare-specific communication tools are designed for this purpose.
The second category is educational and relationship-building communication — newsletters, health tips, practice news, seasonal health reminders, and similar content that is sent to a patient list but does not reference individual patient health information. A newsletter about seasonal allergy management, an update about a new service the practice is offering, or a reminder that flu vaccines are available does not involve PHI in the same way that an individual appointment reminder does — provided it is sent to a general patient list without personalization that links specific health information to specific individuals.
This second category can be managed with a broader range of platforms, though the BAA question still applies if the platform stores or processes any data that could be connected to patient status. The safest approach is to use a platform that offers a BAA regardless of whether a specific communication appears to involve PHI — because the line between the two categories is not always clear in practice, and erring toward compliance is the appropriate default in a regulated environment.
Building a Patient Email List Correctly
The foundation of any email program is a list of people who have given informed consent to receive communications from your practice. In healthcare, this consent should be explicit and documented — not assumed based on the fact that a patient provided an email address for appointment confirmation purposes.
Patients who provide contact information for clinical purposes — to receive appointment reminders, to be reached by the office — have not necessarily consented to receive marketing or educational email communications. The consent for those two purposes is distinct, and treating clinical contact information as automatic permission for marketing email is both a compliance risk and a patient relationship risk.
The consent process does not need to be burdensome. A simple checkbox on a new patient intake form — clearly worded, not pre-checked — that asks whether the patient would like to receive periodic health information and practice news from the office is sufficient for most purposes. Patients who opt in are genuinely interested in hearing from you. Patients who do not are telling you something useful about their communication preferences — and respecting that preference is both the right thing to do and a practical benefit to your email program's engagement metrics.
What to Send and How Often
The content and cadence of a practice email program should reflect what is genuinely useful to patients rather than what is convenient for the practice to produce. Patients who receive emails they find valuable open them, read them, and maintain a positive association with the practice as a result. Patients who receive emails they find irrelevant or too frequent unsubscribe — and in some cases, they form a negative impression of the practice in the process.
Educational content performs consistently well in healthcare email programs. Seasonal health topics — allergy season, cold and flu prevention, summer safety, winter wellness — provide natural content opportunities that align with what patients are thinking about at a given time of year. Condition-specific education for patient populations the practice commonly serves gives patients information that is directly relevant to their health. Practice news — a new physician joining the team, new services being offered, updated office hours — keeps patients informed about changes that may affect their care.
Monthly is an appropriate baseline cadence for most practices. It is frequent enough to maintain awareness without being intrusive, and it is achievable as a sustainable content production commitment. Some practices communicate more frequently during specific seasons or around specific health observances. Others find that quarterly communication better matches the rhythm of their patient relationships. The right cadence is the one that patients find valuable and that the practice can maintain consistently — inconsistent email programs that publish intensively for a period and then go silent for months are less effective than a modest but reliable schedule.
Every email should have a clear purpose and a clear call to action. A newsletter that covers three topics and ends without directing the reader anywhere leaves engagement on the table. Whether the call to action is scheduling an appointment, reading a blog post, learning about a new service, or simply calling the office with questions, giving patients a next step converts interest into action.
Subject Lines and Open Rates
An email that is not opened does not accomplish anything. Subject lines are the single most important factor in whether a patient opens a practice email — and they are worth more deliberate attention than they typically receive.
Effective subject lines for healthcare email are specific rather than generic, informative rather than promotional, and direct rather than clever. A subject line like "What to know before your flu shot this season" will consistently outperform "Fall Newsletter" because it tells the reader exactly what they will find inside and why it might matter to them. Medical practice patients are not looking for entertainment in their inbox — they are looking for information that is relevant to their health. Subject lines that signal that relevance clearly and quickly earn better open rates.
Avoid subject lines that use promotional language — words like "free," "limited time," and "act now" that trigger spam filters and that are inconsistent with the tone of a medical practice. Avoid vague subject lines that give no indication of content. And avoid subject lines that make clinical claims or that suggest urgency around health matters the email cannot genuinely address — these create expectations the content cannot fulfill and erode the trust the email program is designed to build.
Unsubscribes and List Maintenance
Every commercial email sent in the United States is governed by the CAN-SPAM Act, which requires among other things that every email include a clear and functional unsubscribe mechanism and that unsubscribe requests be honored promptly. HIPAA does not override CAN-SPAM in this respect — patients who wish to stop receiving marketing or educational email from your practice have the right to do so, and that right must be respected regardless of the ongoing clinical relationship.
Unsubscribes are not failures. They are useful information about which patients want to hear from you and which do not. A list from which disengaged patients have opted out is a more valuable list than a larger one that includes people who are not reading your emails — because engagement metrics, over time, affect email deliverability. A practice email program with consistently low open rates and high unsubscribe rates will find its emails increasingly routed to spam folders, reducing the reach of communications to the patients who do want to receive them.
Regular list hygiene — removing addresses that consistently bounce, updating contact information when patients provide new details, and segmenting the list over time to allow more targeted communication — maintains the health of the email program and the deliverability of its communications.
How Doctor Rebrand Approaches Email Marketing
Email is a channel we help practices build deliberately rather than reactively. That means starting with the compliance foundation — platform selection, BAA status, consent processes — before addressing content strategy. It means developing a content calendar that gives the email program a consistent cadence rather than relying on whoever has time to write something when the last newsletter was too long ago. And it means building the email program as part of a broader patient communication strategy rather than as a standalone tactic.
For practices that have an existing patient list but no active email program, we help evaluate what has been collected, how consent was obtained, and what the appropriate starting point is for reengaging that list. For practices building from scratch, we design the consent and collection process as part of the new patient intake workflow so that the list grows naturally as the practice does.
The Bottom Line
Email marketing for medical practices is not complicated — but it requires more deliberate setup than the general marketing guides suggest, because the compliance requirements of healthcare add a layer that most email marketing advice does not address.
A practice that gets the foundation right — compliant platform, proper consent, appropriate content — has access to one of the most cost-effective and durable patient communication tools available. The patients on your list already know you. Staying in regular, useful contact with them is one of the simplest ways to ensure that when they need care, or when someone they know needs a physician, your practice is the first one they think of.
