Email marketing is one of the most effective ways to reach customers, but it also comes with responsibility. Under GDPR, every email you send must respect data protection rights and be backed by clear, informed consent.
Why GDPR matters in email marketing
GDPR (General Data Protection Regulation) applies to any business processing the personal data of individuals in the EU, including email addresses. Even if your business is outside the EU, the rules still apply if you are contacting EU residents.
Ensuring compliance with data protection regulations is paramount not only because it is the law, but also because it builds trust with your subscribers by ensuring people receive emails they genuinely want.
How to collect GDPR-compliant consent
Obtaining explicit consent from your audience is the foundation of GDPR. To comply, you need to be clear and specific. People should actively choose to subscribe, for example by ticking an empty box on a form. It should be obvious what type of content they will receive, whether it is a newsletter, promotions or updates. Consent must not be hidden within terms and conditions and you should always keep a record of when and how it was given.
What to include in your marketing emails
Every marketing email must clearly identify your business. Include your business name and contact information, and always link to your privacy policy so subscribers can see how their data is being used. Make it super simple for your users to unsubscribe from your email list with a clear and readily available unsubscribe link in every email you send.
The importance of your privacy policy
Your privacy policy is key to GDPR compliance. It needs to explain what data you collect and why, how long you keep it and how people can opt out or request deletion. If you use third party platforms, such as Mailchimp or Klaviyo, this should also be made clear. Keeping this policy simple and easy to understand is key.

Going beyond compliance
Being compliant is the minimum requirement, but there are extra steps you can take to help to build trust with your audience.
- Granular consent: Consent is not a one-size-fits-all concept. Offering granular options allows users to choose the specific types of communication they wish to receive. This not only aligns with GDPR requirements but also enhances the user experience by tailoring content to individual preferences. So it benefits you too!
- Double opt-in: Consider implementing double opt-in, where users confirm their subscription through a link in a separate email, providing an extra layer of verification.
- Education and training: Equip your team with the knowledge and skills needed to uphold GDPR compliance. Regular training sessions on data protection principles and changes in regulations are essential to foster a culture of compliance within your organisation.
Example consent
On Action Cancer’s website, when you go to register for any event or service, you are explicitly asked if you would like to opt in to their email marketing with the option to check “Yes” or “No” via radio button. This is positive consent, meaning the user isn’t opted in automatically or has to unselect an opt-in when going through the process. This is explicit, freely given consent.

Quick GDPR checklist for email marketing
- Consent: Get clear, informed opt-in via unticked checkbox.
- Transparency: Explain what type of emails subscribers will get.
- Opt out: Always include a working unsubscribe link.
- Privacy policy: Link to a clear, accessible privacy notice.
- Identity: Show your business name and contact details.
- Data tracking: Disclose email tracking and cookies if used.
Final thoughts
GDPR in email marketing isn’t about adding hurdles, it’s about respecting your audience and strengthening your brand. By keeping consent clear, being transparent in your emails, and updating your privacy policy, you’ll not only stay compliant but also build trust with subscribers who genuinely want to hear from you.
