AhaSend vs Postmark
A comparison of AhaSend and Postmark built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
- Pick AhaSend if
- EU-resident sending where you want to choose how long message data is kept — retention is a setting with a floor of zero on paid plans, not a policy you inherit.
- 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.
4 sourced criteria separate them:
- Entry paid plan
- AhaSend: $10/month for Pro; Max is $80/month.
- Postmark: $15.00/month for Basic at the 10,000-email tier. Postmark prices by volume, so the figure rises with the slider.
- Pricing model
- AhaSend: Volume plans on EU multi-region infrastructure, with retention as a plan axis rather than a fixed policy — every tier states a range, and the floor is zero on the paid plans.
- Postmark: One monthly price per volume tier, chosen on a slider, covering both sent and received email. Overage rates improve as the plan gets larger.
- Emails included
- AhaSend: 25,000 a month on Pro and 100,000 on Max. The free plan allows 1,000.
- Postmark: 10,000 a month at the $15 Basic tier. The plan price scales with volume — 50,000, 125,000, 300,000, 700,000 and 1.5M are the published steps. The free tier is 100 a month.
- Log retention
- AhaSend: Configurable rather than fixed: 1 to 7 days on the free plan, 0 to 14 on Pro and 0 to 30 on Max. The lower bound of zero means retention can be turned off entirely.
- Postmark: 45 days on Basic. Pro and Platform default to 45 days and can be raised to 365.

Consider something else if…
- AhaSend: The published table stops at 100,000 emails and does not state a per-thousand overage rate, so what happens past the plan ceiling is not documented.
- 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.
