Actual quote from Postmark.
Postmark stops at transactional emails.
AutoSend doesn't.
Postmark is built for transactional emails. Password resets, receipts, notifications. They're great at it. But that's where it ends.
The moment you want to send a newsletter, build an onboarding sequence, or re-engage churned users, you're stitching in a second tool.
AutoSend covers the whole picture. Transactional, marketing, and automations — one platform, one bill.
