Postmark enables web applications to deliver and track transactional emails quickly, with minimal setup and no maintenance. Sending can be done via their API, ready-made libraries, or SMTP interface. To protect deliverability, Postmark keeps promotional and transactional emails on separate sending infrastructures, so critical emails like password resets or notifications always arrive fast.
Postmark was originally built by Wildbit, the makers of the ESP platform Newsberry. In May 2022, Postmark was acquired by ActiveCampaign but continues to operate as a standalone product.
