Postmark has a reputation for high quality. Even though there are several good companies, we were convinced by Postmark’s clear documentation and transparent roadmap. Further, building email infrastructure is really a partnership — we wanted to invest in a platform that would continue to grow along with our needs, not one that was fairly static and falling behind the technology curve.
