What GDPR means for your email marketing

GDPR is the EU/EEA regulation that sets the rules for the collection and processing of personal data. For email marketing, that usually means having a clear lawful basis (most often consent), being transparent about what you collect, and respecting subscriber rights.

Serious breaches can attract fines of up to €20 million or 4% of total annual worldwide turnover, whichever is higher. The platform you choose doesn't deliver compliance on its own – but the right one can make doing the right thing the path of least resistance.

GDPR compliance illustration

When do you need consent to send marketing emails?

Before almost every marketing email you send to people in the EU/EEA. The ePrivacy rules require consent or a narrow soft opt-in before a marketing email is sent, and GDPR requires a lawful basis for the addressee. The safest default is clear opt-in consent with a record of it.

What valid consent looks like

01 Unticked by default

They tick it – you don't tick it for them.

02 Not buried in terms

A standalone choice, not hidden in the fine print.

03 Clear on what you'll send

Name the content and rough frequency.

Consent, legitimate interest, or soft opt-in?

Basis
When it can apply
The catch
Consent Art. 6(1)(a)
The cleanest basis – the person actively opted in.
Must be optional, and easy to take back.
Legitimate interest
Can cover underlying processing; sometimes limited to B2B.
On its own, it usually isn't enough to send the email – you'll still need consent.
Soft opt-in ePrivacy
Email existing customers about similar products.
Existing customers only, with an easy opt-out every time.

What data do you process, and who's responsible

Most email marketing systems handle contact details, consent records, engagement data, and technical data such as IP addresses and location data. Collect only what you need – the less you hold, the easier requests become.

The concept: controller vs. processor

Data controller You
Decides Why & how data is used, the lawful basis, what to send.
Responsible for Consent, transparancy, rights, list accuracy.
Governed by GDPR controller obligations.
Data processor Sender
Decides Nothing about purpose - provides the tools.
Responsible for Securing data, processing only as instructed.
Governed by A DPA under GDPR Article 28.

What that looks like with Sender

You own
The right lawful basis for each campaign Privacy notices & form copy Honouring subscriber rights requests A clean list & what data you collect
Sender handles
EU-hosted infrastructure & security Consent tooling – forms, double opt-in, logging Data export & deletion tools A designated DPO

Transactional vs. marketing emails

Transactional
Tied to a specific action or contract – order confirmations, shipping updates, password resets. No marketing consent needed
Marketing
Promotes your products or services – newsletters, offers, announcements. Consent rules apply

The trap: drop a promotion into an order confirmation, and that "transactional" email can count as direct marketing – which pulls it back under the consent rules. Keep receipts functional, and keep selling in your campaigns.

How Sender supports GDPR-compliant email marketing

EU data hosting, no asterisks

Your subscribers' data stored in Sender is hosted in the European Union by default – no transfer mechanism to evaluate, no certifications to chase.

EU-based infrastructure on every plan, including the free tier
Procurement and legal reviews go faster when there's nothing to transfer

Consent collection that actually holds up

Build signup forms built to support your privacy review, with the rules baked into the builder.

Granular consent checkboxes (never pre-ticked)
Double opt-in with timestamped confirmation
Automatic logging of every submission for your audit trail
As the data controller, you decide what to collect and how – Sender gives you the tools.

Subscriber rights, handled in minutes

Turn data access and deletion requests into an afternoon, not a project.

Export a single subscriber's data straight from their profile
Delete profiles with a clean audit record of when and why
Direct line to dpo@sender.net for anything that needs a person

Segmentation that respects consent

Segment your list however you need without ever emailing someone who didn't sign up for it.

Segment by location, engagement, any profile field, and more
Exclude specific segments from any campaign with a click
Unsubscribes are removed from your lists automatically – no manual cleanup

One profile per subscriber

GDPR access requests get easier when you don't have to assemble the answer from five different places.

Consent, contact details, and signup source in one view
Full send and engagement history on the same profile
View, export, or delete the entire record in one place

A platform that polices itself

We check accounts on the way in, so the senders sharing infrastructure with you aren't dragging your deliverability down.

Account review at signup and after major list uploads
Purchased and scraped lists screened and flagged before they can be sent
Cleaner sending neighborhood = better inbox placement for you
Built for your team

FAQ

1.

What is GDPR-compliant email marketing?

It means handling subscriber data with a valid lawful basis – most often clear, explicit consent – being transparent about what you collect and why, honoring subscriber rights (access, deletion, withdrawal), and keeping that data secure. The platform you choose plays a supporting role; the practices are yours to own.

2.

Where is my subscriber data stored?

All Sender subscriber data is hosted in the European Union. That means it stays within EU/EEA data protection jurisdiction by default – no extra setup, no separate paid tier.

3.

Do I need consent to send marketing emails under GDPR?

In most cases, yes. You need a valid, lawful basis – usually clear, explicit consent – before sending marketing emails to people in the EU/EEA. Some narrow exceptions exist, such as soft opt-in for existing customers under ePrivacy rules in certain countries.

4.

Is double opt-in required by GDPR?

Not as a flat rule. Double opt-in is widely considered best practice because it creates a verifiable audit trail that helps demonstrate consent was genuine. Some jurisdictions treat it as effectively required; others don't. The ePrivacy Regulation, meant to standardize this, was withdrawn in 2025, so rules still vary by member state. Sender supports it natively either way.

5.

How does Sender check that lists are consent-based?

We review accounts to make sure data is only being collected from people who have given consent. If a list looks like it wasn't built on a valid basis (e.g. purchased or scraped), we'll flag it. It protects your sender reputation and our network.

6.

Does Sender offer a Data Processing Agreement (DPA)?

Yes. A DPA is available on request and covers Sender's role as a data processor under Article 28 of the GDPR. Contact our team and we'll send it over.

7.

How do I contact Sender's Data Protection Officer?

Email dpo@sender.net. Our DPO handles GDPR-related questions and rights requests directly.

8.

Can I track email opens and clicks under GDPR?

Tracking involves personal data, so be transparent about it in your privacy notice, offer a clear opt-out where appropriate, and document your approach. In some EU/EEA countries, ePrivacy rules may also apply.

9.

What does Sender handle, and what stays my responsibility?

Sender acts as your data processor – we provide the EU-hosted infrastructure, the security controls, the consent tooling, and the DPO. You remain the data controller: you decide what data to collect, on what lawful basis, how to write your privacy notice, and how to honor subscriber rights.
