## Which should you choose?

Pick SMTP2GO if Steady sending where the overage rate matters more than the plan fee — $0.85 per thousand on Professional is the lowest published here, and 30 days of reporting comes on every paid tier rather than as an upgrade.

Pick Postmark if Teams that need to answer "what happened to this message" weeks later — 45 days of retention as standard, extendable to a year, is the longest window in this set.

Consider something else: SMTP2GO — A dedicated IP needs the $75 Professional plan, and the entry tier's 10,000 emails is a quarter of what Resend includes for twice the price.

Consider something else: Postmark — The included volume is small for the price and overage is the most expensive here at $1.80 per 1,000 on the entry plan.
