MailerSend vs SMTP2GO
SEPT 2026 auditA comparison of MailerSend and SMTP2GO built from values read directly from each provider's own documentation, with the source recorded against every figure.
The short answer
Choose MailerSend if…
Teams sending email and SMS from one provider who need a longer activity window than a debugging log — 30 days of activity data against 7 days of API logs is a distinction the rest of this category does not draw.

Choose 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.

Consider something else if…
- MailerSend: Both paid tiers include the same 50,000 emails, so paying three times more buys features rather than volume, and the entry price is the highest here.
- 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.
