Consider something else if…
- 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.
- 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.
