We’re profitable, privately owned, and in this for the long-haul. Since 2010 we’ve delivered billions of emails for companies of all sizes.
We rely on Postmark’s high quality sender reputation. This allowed us to ramp up our outbound volume quickly while we migrated from another provider.
Your customers expect transactional emails to arrive immediately—not eventually. We constantly monitor our delivery speeds and share the data publicly.
Customer feedback gathered through Help Scout over the past 60 days.
