Choosing a European Postmark alternative
Postmark built its reputation on fast, reliable transactional delivery and was one of the first providers to separate application streams from broadcast streams. It became part of ActiveCampaign in 2022.
Pricing is on the premium side: 100 emails per month free, then $15 for 10,000. Streams, dedicated IPs, and inbound parsing are core to the offering.
For an EU-based equivalent, AhaSend and Lettermint follow the streams model most closely. The table lists more European alternatives, most of which support SMTP and a Postmark-style REST API.

If you use Postmark's SMTP relay, migration is a credential swap. If you use the Postmark REST API, EU providers offer similar JSON patterns, so the rewrite is usually a thin adapter. Re-verify your sending domain (DKIM, SPF, DMARC) on the new provider and plan a brief warm-up period for any dedicated IPs.
