Email Marketing for Therapists: A Newsletter for Referrals, Not Review Asks

Email marketing for therapists works best as two things: a short monthly newsletter for the people who refer clients to you and the former clients who asked to stay in touch, and a brief follow-up sequence for inquiries that have not booked yet. It is a relationship channel, not a broadcast.

Many practice newsletters go only to current clients, who are already in care. A newsletter does more when it reaches the people deciding whether to send someone your way, or whether to book.

The point is to stay in mind for the people who refer clients to you. A family physician who has read your monthly email for a year has a name ready when a patient asks about CBT for health anxiety.

Email also helps after someone contacts you. When a prospective client fills out your contact form and does not book right away, a short sequence of follow-up emails keeps the door open until they are ready.

The first question most therapists ask is ethical: who can I email, what can I say, and does HIPAA apply?

Start here: your marketing email list is not your current client caseload. You are not sending clinical communication to current clients. You are sending marketing email to:

• Referral partners (PCPs, psychiatrists, school counselors, EAP coordinators). These are business communications.
• Former clients who explicitly opted in after termination. They chose to receive marketing emails.
• Website inquiries who provided their email address. They initiated contact.
• Webinar or event attendees who opted in at registration
• Colleagues from your professional network

Content that works:

• Mental health insights and research (brief, accessible, not clinical advice)
• Resources you genuinely recommend: books, apps, podcasts
• Practice updates: new services, new availability, new insurance accepted
• Awareness month context (May = Mental Health Awareness Month, September = Suicide Prevention Month)
• Educational content relevant to your specialty

Content to avoid:

• Anything that could identify a current or former client, even anonymized case studies
• Any request for a review, rating or testimonial, to anyone on the list (the next section explains why)
• Clinical advice that could be misapplied without context
• Outcome claims that the FTC would consider misleading

Former clients are usually described as the warmest audience a practice newsletter has. That is also what makes them the audience your ethics code is written about.

The former-client list that email marketing guides recommend is exactly where ACA C.3.b, AAMFT 9.2, APA 5.05 and NASW 4.07(b) apply, so a therapist's newsletter must never carry a review or testimonial ask, the line WebsiteTherapy holds by never asking a practice's clients for reviews.

Here is what each code says, in its own words:

• Counselors. The ACA Code of Ethics (2014), standard C.3.b: "Counselors who use testimonials do not solicit them from current clients, former clients, or any other persons who may be vulnerable to undue influence."
• Marriage and family therapists. The AAMFT Code of Ethics, effective January 1, 2026, standard 9.2: "Marriage and family therapists do not solicit testimonials or endorsements from current clients or from other persons who are vulnerable to undue influence."
• Psychologists. The APA Ethical Principles of Psychologists and Code of Conduct, standard 5.05: "Psychologists do not solicit testimonials from current therapy clients/patients or other persons who because of their particular circumstances are vulnerable to undue influence."
• Social workers. The NASW Code of Ethics, standard 4.07(b): "Social workers should not engage in solicitation of testimonial endorsements (including solicitation of consent to use a client's prior statement as a testimonial endorsement) from current clients or from other people who, because of their particular circumstances, are vulnerable to undue influence."

All four codes bar asking current clients and anyone vulnerable to undue influence. Only the ACA code names former clients in so many words. The other three do not, but a former client can still be vulnerable to undue influence, and a newsletter has no way to tell which ones are.

The APA's practice arm applies the same standard to online reviews. Its guide, How to take charge of online reviews, puts it plainly: "Standard 5.05 says you can't solicit testimonials from current clients or from past clients who are vulnerable to your influence."

The codes speak to asking, so the fix is to take the ask out. The newsletter's call to action is "refer a client," "book a consultation" or "reply with a question," never "leave us a review." That holds for the follow-up sequence and the P.S. line too. For handling the reviews you already have, see Google Reviews for Therapists: The Ethics + AI Guide.

Most therapists think of an email list as "clients." Reframe it: your most valuable email audience is your referral partner network.

Referral partners are the people who send clients your way: primary care physicians, psychiatrists, pediatricians, OB/GYNs, school counselors, EAP coordinators, attorneys (family law, disability), oncologists, physical therapists, and therapists with complementary specialties.

Building this list takes intentional work, but it is finite:

1. List the colleagues who have sent you clients
2. Add local PCPs, pediatricians, and school counselors in your area; a brief introduction email works well here
3. After every professional networking event (state association, local chamber), add contacts
4. When you make a referral to a colleague, add them to your list

A referral partner does not need to have sent clients before to benefit from your newsletter. You are building a relationship, showing up monthly with something useful before you need anything.

Former clients can be added only with explicit, post-termination consent. The cleanest approach: at discharge, offer an optional "stay in touch" checkbox. Your EHR's discharge documentation can include this as an optional field, separate from any clinical forms.

Never add current clients to your marketing list, and never automatically add someone who filled out a new patient intake form: intake is not consent for marketing.

Former clients who stay on your list know where to find you if they need care again.

People who contacted you and have not booked yet get their own short sequence, set out below under "Following Up With Inquiries Who Have Not Booked."

Two sets of rules apply to every newsletter a practice sends, whoever is on the list.

CAN-SPAM. The FTC's CAN-SPAM Act Compliance Guide for Business is direct about referral-partner lists: "The law makes no exception for business-to-business email." Under the guide, a commercial email must:

• Disclose clearly and conspicuously that the message is an advertisement
• Include your valid physical postal address: a street address, a post office box registered with the U.S. Postal Service, or a private mailbox registered with a commercial mail receiving agency. If you practice from home, a P.O. box keeps your home address out of every send.
• Tell recipients how to opt out, and honor an opt-out request within 10 business days

The stakes are per message: the FTC's compliance guide says each separate email in violation is subject to penalties of up to $53,088.

Gmail's sender rules. Google's email sender guidelines apply to anyone sending to Gmail addresses: set up SPF or DKIM for your sending domain, send over a TLS connection, and keep the spam rate reported in Google's Postmaster Tools below 0.3%. Under the same Google guidelines, senders of more than 5,000 messages a day to personal Gmail accounts must set up both SPF and DKIM, add DMARC, align the From domain with SPF or DKIM, and support one-click unsubscribe with a clearly visible unsubscribe link in the body.

A practice newsletter rarely reaches 5,000 messages a day, but Google's rules for all senders apply from your first send. Ask your email platform how it handles SPF, DKIM and the unsubscribe link before you send anything. The spam-rate line is the one a small list crosses fastest, and the usual cause is mailing people who never agreed to hear from you.

For referral partners and former clients, a monthly newsletter is the right cadence. Bi-weekly is too frequent for a mental health practice; quarterly loses continuity.

A monthly newsletter that gets opened follows a simple structure:

Total length: 400-600 words. This is not a blog post. It is a relationship touchpoint, and short ones get read.

Make it look and sound like your practice. Use the same colors, typeface, and voice as your website, so a referral partner recognizes you before they reach your name. That consistency is the core of therapist branding, and an inbox is one more place it shows.

Content calendar by month (sample):

• January: New year mental health goals: "What I'm seeing in practice about January anxiety"
• March: Brain Injury Awareness: share resources, mention any TBI-specialized referrals you're seeking
• May: Mental Health Awareness Month: your take on access to care in your community
• September: Suicide Prevention Month: brief, direct resources for referral partners to share with patients
• October: ADHD Awareness: especially valuable for pediatricians and school counselors
• November: Holiday stress: practical guidance your referral network can pass along

Awareness months are more than content hooks. They show referral partners that you are current, engaged with the broader field, and a reliable resource for their patients.

The one email sequence most worth setting up takes no ongoing effort once it runs: an inquiry follow-up sequence.

When someone submits a contact form or books a free consultation and does not book a first session, a 4-email sequence runs automatically:

The ethical note: these emails are marketing communications to someone who contacted you first. Do not provide clinical guidance in the sequence. Keep it informational, warm, and low-pressure.

A small, warm list opens email from a name it knows. The subject line's job is to give a busy referral partner a reason to open this one.

Subject line formulas that work for therapists:

• The specific insight: "The CBT technique I'm recommending most this month." It gives busy referral partners a reason to open.
• The awareness hook: "September is Suicide Prevention Month: resources worth sharing." It hands referral partners something to pass on that month.
• The colleague question: "Why are so many of your patients asking about EMDR?" It prompts curiosity in medical referral partners.
• The personal note: "A resource I've been sharing with every patient who mentions phone anxiety." It names a problem their own patients bring up.
• The practice update: "Now accepting United Healthcare: a quick note." It tells referring PCPs which of their patients they can now send you.

Avoid:

• Generic subject lines: "May Newsletter," "Monthly Update," "From My Desk"
• All-caps or excessive punctuation: "MENTAL HEALTH AWARENESS MONTH!!!"
• Clickbait inconsistent with your content. The FTC's CAN-SPAM guide expects the subject line to match the message.

For a therapy practice, the platform matters less than how you use it. Before you choose one, check five things:

• A Business Associate Agreement, or nothing clinical. Ask the vendor whether it signs a BAA. If it does not, nothing clinical ever goes through it: no appointment reminders, no session details.
• The sending rules. SPF, DKIM and DMARC on your own domain, and a one-click unsubscribe, per the Gmail rules above.
• A place for your postal address in every footer, for CAN-SPAM.
• Automation for the four-email inquiry sequence.
• A full export of your list, so you can move it later.

The critical nuance on HIPAA: Marketing emails that contain zero PHI are generally fine on any platform. The risk is when practices blur the line, using a marketing platform to send appointment reminders or clinical communications.

One more line to hold: a former client's name on a therapy practice's list can itself show that they were a client. Treat the list as confidential even when no email mentions therapy.

The simplest safe approach: Keep your marketing list completely separate from your EHR. Your marketing platform holds names and email addresses only, never clinical information or anything from a chart. Your EHR handles all clinical communications. No overlap, no ambiguity.

Therapists new to email marketing often get distracted by numbers that do not predict practice growth. Here is what matters:

Track these:

• Referrals generated: Ask every new client "How did you hear about me?" If "Dr. X referred me" increases after you add referring providers to your newsletter, email is working.
• Inquiry-to-consultation conversion: Compare the share of inquiries that book before and after the follow-up sequence runs. Your own before-and-after is the benchmark that counts.
• Open and click rates against your own past sends, not against industry averages. A falling open rate on a warm list usually means the subject lines or the content drifted.
• Spam complaints: the number Gmail watches. Keep it under the 0.3% line in Google's sender guidelines.

Do not obsess over:

• Unsubscribes: People who leave were not going to become referral partners, and honoring their choice is the law.
• List size: A short list of engaged referral partners beats a long list of cold addresses.

Review email results quarterly. Monthly is too granular for a solo or small group practice: you will not have enough sends to draw meaningful conclusions. Quarterly gives you three sends to compare.

If you have never sent a practice newsletter, here is the minimum version to launch this week:

1. Build your referral partner list. List the colleagues who have sent you clients. Add local PCPs, school counselors, and colleagues from professional associations. Twenty to thirty contacts is enough to start.
2. Choose your platform. Pick one that meets the sending rules above, gives your postal address a place in the footer, and stays separate from your EHR.
3. Write your first newsletter. One main insight, one practice update, three resource recommendations. 400 words. Send on the first Tuesday of next month.
4. Set up one automated sequence. Even a 2-email inquiry follow-up (immediate response + Day 3 reminder) is better than a single reply. Build out to 4 emails over time.
5. Commit to 3 months. The first newsletter rarely books anyone directly. By the third, a referring physician has seen your name in their inbox three times.

Before each send, read it once for the review ask. If "leave us a review" crept into a P.S., take it out.

Email marketing pairs naturally with a well-optimized local presence. See also: Social Media for Therapists: The 2026 Ethics & Growth Guide.
