Postmark is run by Wildbit, a software company founded in 1999 in Philadelphia. We built Postmark while running Beanstalk, and we felt completely blind for emails being sent from our web app. With existing knowledge in email delivery, we decided to tackle the problem ourselves. We’re profitable, debt-free and privately owned. Since 2010 we’ve sent billions of emails for customers, bringing better visibility and inbox rates for transactional email.
