Email is the highest-ROI channel a wellness practice can run, but in healthcare it comes with a rule no other industry has to clear: marketing that uses protected health information generally needs the patient’s written authorization, and any vendor touching that data has to sign a business associate agreement. Get the compliance right and email quietly becomes your most profitable channel.
A patient relationship is built on trust, and the inbox is where that trust either compounds or breaks. Medical, dental, and healthcare emails average a 43.75% open rate, and health and fitness emails reach 47.81%, both ahead of the 43.46% all-industry benchmark. People open practice email because it is relevant to their health, which is exactly why a careless send (a condition named in a subject line, a list segmented by diagnosis without consent) does real damage. The performance is the prize and the compliance is the guardrail; you do not get one without the other.
The buyer-intent data tells the same story. Search volume for this niche is thin (“healthcare email marketing” runs around 500 US searches a month), but the cost-per-click is not: “email marketing for doctors” carries a $20.00 CPC and “HIPAA compliant email marketing” an $8.00 CPC. Practices are not shopping for an email tool. They are screening for a partner who can run the channel without a HIPAA violation. That is the whole brief, and every number on this page is backed by a real source, listed at the bottom.
The case for doing this differently is not our opinion. It is what the data says, every figure sourced below.
Patients open practice email more than almost anyone opens anything.
Email outperforms in this niche for a simple reason: it is wanted. Medical, dental, and healthcare emails average a 43.75% open rate and a 7.31% click-to-open rate in MailerLite’s analysis, meaning once a patient opens, more than one in fourteen click through. Health and fitness sits even higher on opens at 47.81%. Both clear the 43.46% all-industry average, and an independent benchmark from Innerspark confirms the direction on its own scale: healthcare opens around 22.6% and clicks around 2.8%, above the cross-industry norm of roughly 21% and 2.3%.
Treat opens as directional, not gospel (Apple Mail Privacy Protection inflates them unevenly across tools), which is why we lead on click-to-open and revenue, the numbers that survive that noise. The takeaway holds either way: when a real patient relationship sits behind the send, attention in the inbox is unusually high. That attention is the asset email is built to monetize, and it is the reason this channel deserves a real seat in your mix rather than a quarterly newsletter nobody schedules.
Healthcare email opens at 43.75% and health and fitness at 47.81%, both ahead of the 43.46% all-industry average.
Wellness inboxes open above the average
Email returns more per dollar than any other channel you run.
The case for email is not subtle once you look at return. The industry average sits at $36 to $42 back for every $1 spent, which puts it ahead of paid and social on pure efficiency. For a wellness practice weighing where the next marketing dollar goes, that is the argument: email does not replace paid acquisition, it makes the patients that acquisition wins worth far more over their lifetime, because the relationship keeps producing visits, referrals, and reviews long after the first appointment.
Compare that to the cost of buying attention. Healthcare search ads run a $5.64 average cost-per-click and a $66.02 average cost-per-lead, and those numbers climb in pricier sub-niches. Email is how you stop paying that toll twice. A patient you already acquired, nurtured by email, comes back without another $66 lead bill, which is why we treat email as the compounding layer underneath your paid program rather than a standalone tactic.

The highest-value email in a practice is rarely the newsletter. It is the automated one: the welcome series, the appointment and recall reminders, the refill nudge, the post-visit follow-up, the reactivation of a patient who has not booked in a year. In Omnisend’s 2025 data, automated emails drove 30% of all email revenue from just 2% of sends, and earned 16x more per send than scheduled blasts ($2.87 versus $0.18). The reason is timing and relevance: an automated message reaches the patient at the moment it matters.
For a wellness practice, this maps directly onto operations. Recall and recare automations fill the calendar without staff making calls. Reactivation flows win back lapsed patients you already paid to acquire. Post-visit follow-up earns the review that drives your next patient. We build these flows once, gate them to the right consent, and they run quietly in the background producing revenue at a per-send rate the manual newsletter cannot approach.
Automated emails drove 30% of email revenue from 2% of sends, earning 16x more per send than blasts.
A sliver of sends, a third of the revenue
One message to everyone is the easiest revenue to leave behind.
A med spa, a dental practice, and a physical therapy clinic each serve patients with different reasons to open. Sending the same email to all of them is the default, and it is also the cheapest mistake in the channel. The DMA puts the lift from segmented campaigns at a 760% increase in email revenue. In a practice, the segments are obvious once you look: service line, visit history, lifecycle stage, season.
This is where compliance and performance line up rather than fight. Smart segmentation does not require exposing protected health information in the email; it requires organizing your list so the right patient gets the right relevant message, delivered through a vendor and process that keep that data protected. We build the segmentation strategy and the consent structure together, so the targeting that drives the revenue is the same targeting that keeps you on the right side of the rule.
Relevance is the revenue lever
The DMA attributes a 760% revenue increase to segmented email campaigns over unsegmented sends.
Source: Mailmodo Email Segmentation Statistics (citing DMA)Marketing with patient data needs consent, and a vendor that signs.
This is the line that makes healthcare email its own discipline. Under HIPAA, a covered entity generally must obtain a valid written authorization before using or disclosing protected health information for marketing. Protected health information is any data linking an email recipient to specific health details, which means a list segmented by condition or a subject line that names a diagnosis can cross into territory that requires consent. Treatment and care-coordination messages (an appointment reminder, a refill notice) sit outside the marketing definition, which is why those automations are both the safest and the most valuable to run.
The second guardrail is the vendor. Any email platform that touches protected health information has to sign a business associate agreement, and most consumer email tools will not. The elevated CPCs on terms like “HIPAA compliant email marketing” exist because buyers know this is where programs go wrong. We build to comply by design: consent captured correctly, lists structured so protected data never rides in the message, a vendor under a signed BAA, and treatment messaging kept distinct from marketing. You should never have to choose between an email program that performs and one that keeps you compliant.
A covered entity must obtain valid HIPAA authorization for any use of protected health information for marketing.
Few people search for this, and the ones who do are buying.
The temptation with a channel page is to chase volume, and here the volume is not the story. “Healthcare email marketing” draws roughly 500 US searches a month, with most related terms in the 100 to 200 range. That is thin. What it is not is low-value. The cost-per-click on “email marketing for doctors” is $20.00, and “HIPAA compliant email marketing” commands $8.00 at a keyword difficulty of just 3, a signal that demand is high-intent and lightly contested for the partner who can speak to it credibly.
The strategic read: this is not a page that wins on traffic, it is a page that wins on fit. The practices searching these terms have a budget and a specific worry, and they are screening for one capability before anything else. So rather than write generic email copy, we lead with the compliance answer they came for and back it with the performance numbers that justify the investment. That is the same logic we apply to the program itself: solve the patient-data question first, then let the channel’s economics do the selling.
Thin volume, high-value intent
HIPAA defines PHI as individually identifiable health information, meaning any data linking an email recipient to specific health-related details falls under this category.

A covered entity must obtain a valid HIPAA authorization for any use or disclosure of Protected Health Information (PHI) for marketing.

This is typically only allowed if covered entities receive a patient’s authorization.
