Consider something else if…
- 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.
- Mailgun: One day of log retention on the entry plan is the shortest here by a wide margin, and the overage rate is quoted as "from", so the number you plan against is a floor.
