Transactional email service built around receipts, password resets and other triggered mail that has to arrive quickly.

Built by the software studio Wildbit and known for a stubborn obsession with deliverability: Postmark long kept transactional mail and bulk sends on separate servers so a marketing blast could never drag down the reputation of a password-reset email. That discipline is the entire reason to pick a specialised service.

ActiveCampaign acquired Postmark (and its sibling product DMARC Digests) from Wildbit in 2022. It competes with SendGrid and Mailgun in the corner of email where inbox placement matters more than campaign graphics.
