Dental email marketing: a UK guide for practices

Dental email marketing means sending patients emails that promote your practice: a newsletter, news of a new treatment, your membership plan, a reminder that whitening is available. It is different from the service emails every practice already sends, such as appointment confirmations and reminders, and the difference is legal, not just stylistic. Service messages can go to any patient. Marketing emails need either the patient's consent or the "soft opt-in", and one promotional line is enough to turn a service email into a marketing one.

This guide explains where that line sits, what you can send to whom, what to write, and how to tell whether your emails are working.

Service messages and marketing emails: the line that matters

The ICO's guidance on identifying direct marketing says service messages are communications for administrative or customer service purposes, and gives messages that confirm or remind people about appointments as an example. It adds two points every practice should know:

• If a service message has elements that are direct marketing, even if that is not its main purpose, it counts as direct marketing.
• A neutral tone that simply gives information people need as part of their relationship with you makes a message more likely to be a service message, but tone alone does not decide it. Context matters.

The rules for marketing emails

Marketing emails to individuals are governed by the Privacy and Electronic Communications Regulations (PECR). The ICO's guide to electronic mail marketing says you must not send marketing emails or texts to individuals unless:

1. they have specifically consented to marketing email from you, or
2. they are an existing customer who bought, or negotiated to buy, a similar product or service from you, and you gave them a clear chance to opt out when you collected their details and in every message since. This is the soft opt-in.

The ICO adds that you must not disguise your identity, must give a valid address for opting out, and that the soft opt-in does not cover new contacts or bought-in lists. The ICO notes this guidance is under review following the Data (Use and Access) Act 2025, so check it again before a big campaign.

Two practical points for practices:

• Private patients who have paid you for treatment are the clearest case for the soft opt-in, for similar private services, provided you offered the opt-out at the start.
• Patients who have only had NHS care are a less clear fit for "bought or negotiated to buy", and consent is the safer route.

The advertising code also covers marketing emails. Rule 10.1 of the CAP Code says marketers must not make persistent and unwanted marketing communications by any means, and the claims in your emails are held to the same standards as your website and ads.

How to collect consent properly

The best moment is when a patient registers or updates their details:

• An unticked box with plain wording, such as "Email me practice news, offers and information about treatments. You can unsubscribe at any time."
• Separate from consent to appointment reminders, which you do not need consent for in the same way.
• Recorded in your practice management software with the date and the wording shown.
• Easy to withdraw, with every marketing email carrying a working unsubscribe link.

The ICO's guidance on planning direct marketing also notes that people have an absolute right to object to direct marketing. When someone unsubscribes, stop straight away.

Health information: be careful with segmenting

It is tempting to email "all patients who have had a crown" or "everyone with gum disease". The same ICO guidance says special category data, which includes health information, needs a special category condition as well as a lawful basis for direct marketing, and that you should have explicit consent, because it is unlikely any other condition applies. It also warns that inferring health from other data counts.

Treatment history is health information. Unless patients have given explicit consent to marketing based on it, keep marketing segments to non-clinical facts, such as private or NHS, last visit date or whether someone is on your plan, and send clinical information as service messages only when it is genuinely part of their care.

Tracking pixels and open rates

Most email tools add an invisible tracking pixel to report opens. The ICO's guidance on storage and access technologies says that where an email tracking pixel stores or accesses information on a recipient's device, the PECR rules on cookies and similar technologies apply as well as the email rules. Check how your email tool works, cover it in your privacy notice, and consider whether you need open tracking at all. Bookings and replies are better measures anyway.

What to send: dental email marketing examples

Patients open emails from a practice they trust when the email is short, personal and useful. Formats that work for most practices:

• A short quarterly newsletter. One practice update, one useful piece of advice, one reminder of how to book. Signed by a named person.
• New treatment or clinician announcements. Factual, with the price and how to book a consultation.
• Membership plan information for private patients who pay per visit.
• Seasonal practical notes, such as holiday opening hours, combined with a gentle reminder to book.

Every marketing email about treatment must meet the same standards as your ads. The GDC's guidance on advertising requires claims backed by facts and no unjustified expectations about results. Never include anything that could identify another patient.

A simple dental email marketing template

A structure you can adapt:

1. Subject line that says what the email is, in plain words. "New evening appointments at [Practice]" beats anything clever.
2. Opening line addressed to the patient by name.
3. One main message in two or three short paragraphs.
4. One clear action, such as a booking link or phone number.
5. Sign-off from a named person at the practice.
6. Footer with practice name, address, GDC information where the email advertises treatment, and an unsubscribe link.

Plain, text-led emails can feel more personal than heavily designed ones, and they are simpler to read on a phone.

How often to send

Less often than you think. A practice email is welcome when it is occasional and useful, and unwelcome when it feels like a shop. Monthly at most for marketing, with service messages sent whenever they are needed. If unsubscribes rise after a send, that is the clearest signal you have overdone it.

Should you use an email marketing agency?

An agency can design templates and run sends, but the legal responsibility for consent, lawful basis and content stays with you as the practice. If you use one, ask how they record consent and suppression lists, where data is stored, whether they use tracking pixels, and who checks claims against GDC and CAP rules before anything is sent.

Measuring whether it works

Ignore vanity numbers. Track, for each marketing email:

• bookings or enquiries in the following fortnight that mention the email or came through its link
• replies
• unsubscribes
• plan joiners, if the email was about the plan

Frequently asked questions

Can we send recall reminders without marketing consent?

A neutral reminder that a patient is due a check-up, with how to book, is likely to be a service message. Add an offer or a promotion and it becomes marketing, so keep promotions in a separate email to patients who can receive marketing.

Can we buy a list of local email addresses?

Avoid it. The ICO says the soft opt-in does not apply to bought-in lists, and its guidance on collecting information and generating leads lists the checks you would need to make, including whether your practice was named when people consented. In practice, bought lists rarely pass.

Do the same rules apply to text messages?

Yes. The ICO's electronic mail marketing rules cover texts as well as emails, so the same consent and soft opt-in rules apply to marketing texts.

Email works on the patients you already have. Growth also needs new patients finding you, which is a search problem rather than an email one. Our guides to getting more dental patients and marketing for dentists cover how the channels fit together.
