WhatsApp broadcast list for your clinic: how to use it

The broadcast list is one of the most useful and most misused tools in WhatsApp. Done well, it keeps patients informed, reminds them of dates and brings back those who disappeared, all with a personal touch. Done badly, it becomes spam, triggers blocks and puts the clinic in a delicate position with the LGPD (Brazil's data protection law) and with health advertising rules.
This guide shows how to set one up, what to send and how to respect the patient when using broadcast lists at an orofacial harmonization (HOF) clinic. The app's features change often, so confirm them in the version you use. The focus here is on the criteria, which still apply even when the screen changes.
Broadcast list, group or community?
| Feature | How it works | Suitable for patients? |
|---|---|---|
| Broadcast list | Message sent to several contacts; each receives it as an individual chat and cannot see the others | Yes, with consent and moderation |
| Group | Everyone sees the members and replies to each other | Generally no: it exposes patients to one another |
| Community or channel | One-to-many broadcast, with a public or semi-public profile | Can work for general content, never for patient data |
For communicating with patients, the broadcast list is usually the safest option, because it preserves each recipient's privacy. Patient groups should be avoided: it only takes one member knowing who another is to reveal that they are a patient of an aesthetics clinic, and that is personal data.
Consent: rule number one
A marketing message sent through WhatsApp requires consent. That means:
- Ask the patient whether they want to receive news and notices, saying how often and about what.
- Record the answer (in the registration, in the form or in the conversation saved in the patient record).
- Allow opting out easily, at any time, and honor it immediately.
- Do not add people who never agreed, or contacts bought or scraped from another source.
Messages tied to the care the patient contracted (appointment confirmation, aftercare instructions) are different in nature and may follow a different logic. See automatic reminders for HOF patients. For marketing, see LGPD in clinic marketing and the LGPD.
What to send (and what to avoid)
Content that usually works
- Notice of special hours, collective vacations and address changes.
- Seasonal skin care reminders (sun protection, hydration) with no promises.
- An invitation to ask questions or come in for a reassessment, with no pressure.
- Clinic news, such as a new professional or service (according to your professional council's rules).
- A summary of educational content published on the website or on Instagram.
- Messages for special dates, handled with care. See messages for special dates.
Content that usually causes problems
- Aggressive promotions, "last spots" and urgency appeals.
- Prices and discounts beyond what your professional council's rules allow. See advertising harmonization prices.
- Patient photos, before and after images or simulations without a label and authorization.
- Promises of results.
- Long messages with many links.
- Messages sent at 11 p.m. or on a holiday.
Frequency, timing and tone
Less is more. One or two messages a month, on a business day and during business hours, is a pace most patients tolerate well. If patients start blocking or reporting you, the number can be penalized, and the clinic's main channel is put at risk.
Write as if you were talking to a person, not a crowd. Keep messages short, about a single subject, in a kind tone and with a clear way out ("reply STOP to stop receiving these"). If the app allows it, use the patient's name. Use the WhatsApp scripts for HOF clinics as a base.
Segment so you do not annoy people
A single list for everyone tends to irritate. Split it into groups that make sense for your clinic:
| Segment | Example message |
|---|---|
| Active patients | Hours notice, seasonal care |
| Patients who have not returned in a while | Respectful reassessment invitation. See reactivating inactive patients |
| People who asked for information but did not book | Reply with frequently asked questions |
| Partners and professionals | Technical content and invitations |
Be careful not to organize lists by procedure type in a way that exposes health information if someone sees the list name. Only you can see the list name, but the content you send must not reveal the patient's treatment.
WhatsApp Business: what it offers
The Business version has useful features: catalog, quick replies, labels and away messages. See WhatsApp Business for HOF clinics. Use labels to organize contacts and to record who authorized marketing contact. Do not use bulk-sending programs that go against the app's rules: they can get the number banned and lead to sanctions.
Measuring without fooling yourself
Track how many people replied, how many asked to leave, how many bookings came after a message and how many blocks occurred. A small, engaged list is worth more than a huge, cold one. Hypothetical example: if, after a message to 200 contacts, 12 reply, 3 book and 4 ask to leave, the takeaway is that the content drew interest, but the frequency or topic needs care. The numbers are made up purely to illustrate.
When the list is not the best tool
Not all communication fits in a list. A conversation about a concern, a clinical question, a personalized quote and any report after a procedure should happen in an individual chat, answered by a team member. The list is for general notices, not for patient care.
It is also worth remembering that WhatsApp is only one channel. For longer content, email or the clinic's website are more suitable, and the list can simply point to them. See email marketing for HOF clinics. Combining channels avoids depending on a single number, which can be blocked or lost.
Common mistakes
- Adding patients without asking.
- Creating a patient group.
- Sending every week.
- Mixing care notices with promotions.
- Exposing the patient's procedure in the message.
- Ignoring people who ask to leave.
- Using a bulk-sending program.
How Harmy fits in
Harmy does not manage broadcast lists. In the app, the before and after image comes out with the clinic's header and the notice that it is an illustrative simulation, not a promise of results, and the patient link opens the slider on the patient's phone, with the clinic's logo and contact. If you share something through WhatsApp, do it individually, with the patient's authorization. Do not send patient images to broadcast lists.
Summary
A broadcast list works when it respects the patient: recorded consent, easy opt-out, few messages, useful content and nothing that exposes health data. Prefer a list over a group, segment your contacts, and measure replies and opt-out requests to adjust the pace.
Frequently asked questions
What is a WhatsApp broadcast list?
It is a feature that lets you send the same message to several contacts, who receive it as an individual chat and cannot see the other recipients. In general, it only reaches people who have the clinic's number saved, and the app's rules may change.
Can I add patients to the list without asking for permission?
Ideally, ask. Marketing messages require specific consent, and the patient must be able to leave the list easily. Check with your legal advisor which legal basis applies to your case.
How often should I send messages?
In moderation. For many clinics, one or two well-spaced, useful messages a month is enough. Too many lead to blocks and reports, and can hurt the number's reputation.
What should I send to the list?
Useful content with no promises: notice of special hours, seasonal care reminders, clinic news and invitations to ask questions. Avoid aggressive promotions, prices that go against your professional council's rules, and patient images.
Are a broadcast list and a group the same thing?
No. In a list, each person receives the message individually and cannot see the others. In a group, everyone sees the members and replies to each other, which exposes data and is generally not appropriate for patients.
