## Notes

Postmark is a hosted e-mail delivery service that sends transactional mail for applications through an HTTP API and an SMTP service. Applications authenticate with a server token, and the service reports delivery events and can receive inbound e-mail. AC PM, LLC is the contracting party in its terms and a related body corporate of ActiveCampaign, according to ActiveCampaign's privacy policy.

## Worth knowing

No self-hosted install is documented, so an application that sends through Postmark depends on the service for every message. The vendor has no plans for servers in the EU.
