SEPT 2026 audit

A comparison of AhaSend and Resend built from values read directly from each provider's own documentation, with the source recorded against every figure.

The short answer

Choose 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.

Editorial · Palash Bagchi · approved

Choose Resend if…

Projects that want a generous paid allowance for the money — 50,000 emails at $20 is several times what the same spend buys at Postmark or Mailgun.

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.
  • Resend: Log retention is 30 days and not extendable, and a dedicated IP needs the Scale plan plus 3,000 emails a day before it is offered at all.

Those rows lean, and the provider can correct them with a link.
