About Postmark

Postmark is an email delivery service for applications and other senders. Begin with a transactional message such as a sign-in email or receipt, configure the sending domain and follow the message in delivery activity. The service uses message streams to separate different kinds of email. That organization is useful when a team needs to distinguish immediate application messages from bulk communication. Domain authentication, sending reputation and recipient behavior still affect delivery. Review the current plan and stream rules before migrating. Test templates, unsubscribe behavior where appropriate, and how your application handles delivery events or a send that fails.
