About the transactional email category
Transactional email services charge for sending volume, with differences in daily limits, log retention, domains, inbound handling and support. Compare SMTP2GO, Postmark, Mailgun, Resend and SendGrid at the same volume and feature requirements. The April 2026 records do not provide independent inbox-placement or reliability measurements.
How to choose between transactional email options
Estimate normal and peak sending volume, then check daily caps, burst limits and overages. Test delivery events, bounces, suppression handling and retries in the application. If you need inbound replies, confirm the current receiving workflow and retention limits. Price the same domain, support and IP requirements across vendors.
