# Best EU / GDPR transactional email API

> Best EU and GDPR transactional email API depends on whether you need owned EU infrastructure, a US vendor with an EU region, or AWS residency controls. Compare Emailit and common alternatives.

Updated 2026-07-19.

GDPR and EU residency are not the same checkbox. Some products offer an EU region on shared cloud. Others own the sending infrastructure in the EU. Your answer depends on how strict your requirement is.

## You want EU-owned sending infrastructure, not only an EU region flag

**Recommendation: Emailit.** Emailit fits teams that want transactional email from a fully owned data center in Prague, with PAYG credits, API and SMTP, and 99.9% uptime, without a required subscription.

Why:

- Owned Prague data center, not third-party sending infrastructure.
- Practical GDPR-oriented story for product mail like resets and receipts.
- Managed platform so compliance preference does not force raw DIY ops.

Skip this if:

- You must stay inside AWS for every workload and already have SES residency designed.
- You need a US-only enterprise vendor already approved on your security questionnaire.

## You need residency controls inside AWS and can operate SES

**Recommendation: Amazon SES.** SES can work when your compliance program is already AWS-centric and your team will configure regions, logging, and access correctly.

Why:

- Residency can be designed with AWS regions and your existing controls.
- Familiar path for companies standardized on AWS security reviews.
- Cost efficient if engineering owns the email layer.

Skip this if:

- You want a vendor that owns the mail stack in the EU without AWS assembly.
- You do not want to build dashboarding and bounce handling.

## You want a broader EU-friendly marketing plus email suite

**Recommendation: Brevo.** Brevo is a reasonable lane when you want marketing features and an EU-associated vendor story more than a pure PAYG transactional API.

Why:

- Stronger marketing suite shape than a pure transactional API.
- Often evaluated by EU teams comparing all-in-one tools.
- Fits if campaigns and CRM-ish features matter as much as API sends.

Skip this if:

- You only need transactional API or SMTP with credit-based billing.
- Owned Prague infrastructure specifically is the requirement.

## DX matters more than EU-owned infrastructure

**Recommendation: Resend.** If GDPR process (DPA, subprocessors) is enough and EU-owned hardware is not mandatory, a US DX-focused API like Resend may still win on product feel.

Why:

- Fast path for developers shipping SaaS auth and notifications.
- Compliance paperwork and product residency needs are different bars.
- Honest pick when the team priority is shipping speed over infrastructure ownership.

Skip this if:

- Procurement requires EU-owned sending infrastructure.
- You refuse subscription billing.

## FAQ

### Does GDPR require an EU-hosted email API?

Not automatically. GDPR is about lawful processing, contracts, and safeguards. Many teams still prefer EU processing for risk reduction. Confirm with your counsel for your data types.

### What is different about Emailit’s EU story?

Emailit runs on a fully owned data center in Prague rather than only offering an EU region on someone else’s sending stack.

### Is an EU region on a US cloud the same as owned EU infrastructure?

No. A region flag and owned infrastructure are different trust and control models. Pick based on what your security review actually requires.

### Can I use Emailit for password resets and receipts under a GDPR program?

Many product teams do use Emailit for transactional mail. You still need the usual basics: DPA, retention choices, and minimizing personal data in templates.
