European Alternatives to Postmark
US transactional email service, owned by ActiveCampaign. Below are 4 alternatives from companies headquartered in the Netherlands, Estonia and France. 3 of them keep data in the EU only, and 3 have a free plan.
Headquartered in Europe
Every company listed here has its headquarters in the EU, EEA, UK or Switzerland, not just a data centre there.
Data location you can check
The pricing table shows whether each one keeps data in the EU only, offers an EU region, or does not say.
Outside the US CLOUD Act
US providers can be ordered to hand over data held in their European data centres. A European company with no US parent or US operations is outside that reach.

What to Check Before Switching from Postmark
Your sending domain has to be verified again with the new provider. Publish its SPF and DKIM records before moving traffic, and keep the old records until the switch is finished so mail in flight still authenticates.
Postmark keeps transactional and broadcast mail in separate message streams. Check whether the alternative separates them the same way, or send each kind from its own subdomain.
Templates stored in Postmark have to be recreated with the new provider or moved into your application.
Where your data will be stored
3 of the 4 alternatives here say they keep data in the EU only. AhaSend offers an EU region alongside others, so choose it explicitly when you set up the account.
How you can try it
Lettermint, AhaSend and Mailjet have a free plan, so you can run a real test before cancelling Postmark.
Security certifications
We have not confirmed a security certification for any of these alternatives yet. If your procurement requires ISO 27001 or SOC 2, ask each vendor for its documentation.
What you need to bring from Postmark
List the data, templates and integrations you rely on in Postmark, then confirm each one can be exported and that the alternative can import it or offers an API to rebuild it.
