A practice manager asked us this over the summer, and it is one of the most common email questions we get: "We have a list of a few thousand past patients just sitting there. How often are we supposed to email them without being annoying?" It is a great question, because both mistakes are easy to make. Email once a year and you have basically wasted the list. Email every three days and you train people to ignore you or hit unsubscribe.
So here is the straight answer, with the data behind it.
Short version: once or twice a month is the sweet spot for most practices, plus the occasional timely email when there is a real reason to send one. That is often enough to stay familiar, rare enough that people still open you.
Why not more? Because too many emails is the number one way to lose people
It feels like sending more emails should mean more bookings. It rarely does. The biggest reason people unsubscribe from a business, by a wide margin, is simply that it emails them too often. In HubSpot research on why consumers hit unsubscribe, "receives too many emails" sits at the top of the list, cited far more than boring content or anything else.
And an unsubscribe is not even the worst outcome. The worse one is the patient who does not bother to unsubscribe and just marks you as spam instead. Enough of those and inbox providers like Gmail start filing your emails in the spam folder for everyone on your list, including the patients who genuinely wanted your recall reminders. Over sending does not just annoy a few people. It quietly wrecks your ability to reach the ones who care.
This is the same lesson we keep coming back to with social media and posting frequency: the goal is a steady rhythm you can keep, not a volume contest. With email, restraint is a feature.
Why not less? Because email is one of the best returns in marketing
On the other side, a lot of practices barely email at all, and that is money left on the table. Email marketing consistently posts one of the highest returns of any channel: industry figures from Litmus put it around 36 dollars back for every 1 dollar spent. Healthcare tends to do even better than average on open rates, because these are not cold strangers. They are people who have already sat in your chair and trust you.
Think about who is on that list. Past patients who drifted. People who booked once and never came back. Patients overdue for a cleaning, an annual, a follow up. A single well timed email that says "you are due, here is the link to book" is one of the cheapest new appointments you will ever get, compared to paying for a brand new patient through ads. That is why going silent is its own kind of expensive.
A simple monthly email plan you can actually keep
If you want a template, try this: one solid email a month as your baseline. Rotate the theme so it never feels the same: a seasonal health tip one month, a "you may be due for a visit" recall the next, a new provider or new service the next, a friendly team update after that. Then add a second email only when something real comes up: a seasonal offer, a schedule change, a genuine local reason. That is it. Twelve to twenty thoughtful emails a year beats forty that nobody opens.
The number that matters more than how often you send
Frequency gets all the attention, but it is the wrong thing to obsess over. The real question is whether people open and act on your emails at all. And that comes down to two things: relevance and timing, not how many you blast out.
An email that arrives because a patient is genuinely due for care, or because a service actually fits their life right now, gets opened. A generic newsletter sent on a schedule because it is "newsletter day" gets ignored no matter how often you send it. So before you worry about cadence, ask a simpler question about every email: would a real patient be glad they got this? If the answer is no, sending it more often only speeds up the unsubscribes.
This is also why segmenting your list matters more than raw frequency. A reminder that lands for the right person at the right time will always beat one more mass send. We dug into building and using that list well in our guide to building an email list for your practice, and into the numbers to watch in what a good email open rate looks like.
Email or text? Use both, for different jobs
A quick note, because owners often ask whether they should even bother with email when texts get read almost instantly. The answer is that they do different jobs. Text is for the urgent, short stuff: appointment reminders and confirmations, where near instant reads matter. Email is for the longer, less urgent messages: recall campaigns, seasonal education, updates, offers. Most practices we work with send the time sensitive things by text and keep email for the once or twice a month stay in touch note. We compared the two directly in text vs email appointment reminders.
One rule that applies to both: never send protected health information over regular email or text. Keep marketing messages general ("you may be due for a visit"), and keep anything clinical inside your secure patient portal.
How EtherealMinds handles practice email
We work only with healthcare practices in the United States, and email is part of the full patient acquisition system we build, not a random newsletter bolted on. That means a sensible monthly cadence, lists split so the right patients get the right message, recall and reactivation campaigns that pull past patients back into your schedule, and copy that sounds like a real person, not a corporate mailer.
And because email only pays off when the rest of the path is ready, it plugs into a fast website that turns the click into a booking, plus our AI receptionist answering the calls and messages those emails set off, day or night. The email gets the patient to raise their hand. The system makes sure someone catches them.
So, how often should your practice email? For most, once or twice a month, plus a timely send when there is a real reason. Not daily, and definitely not never. Keep it useful, keep it human, and let email do what it does best: quietly, dependably filling gaps in your schedule with patients who already know and trust you.
