Postmark is a transactional email delivery service focused on inbox delivery speed and reliability for password resets, receipts, and time-sensitive application emails.
Postmark is a transactional email delivery service founded in 2009 by Wildbit and subsequently acquired by ActiveCampaign, providing developers and product teams with a dedicated sending infrastructure purpose-built for the reliability and inbox delivery performance requirements of application-generated transactional email — password resets, account confirmations, purchase receipts, invoice delivery, and notification emails where delivery failure or delays directly impact the user experience and can prevent customers from completing essential account actions. Postmark's founding philosophy was that transactional email deserved a dedicated sending infrastructure and reputation that was never shared with bulk marketing email — a deliberate architectural decision that has defined its positioning in the developer email infrastructure market.
