About the transactional email category
Transactional email pricing in 2026 splits along one axis: price per 1,000 emails at scale. Resend leads the aggressive pricing curve — Scale tier drops to $0.46 per 1k emails at 2.5M volume, significantly cheaper than Postmark's $1.20 or Mailgun's $1.10. Postmark wins on deliverability reputation; Resend wins on developer experience and cost at scale. SMTP2GO sits in the middle with a clean 100% SLA guarantee and a generous $10/mo Starter. For anyone sending under 10k emails/month, the differences are marginal. Above 100k/month, the per-email cost gap compounds fast.
How to choose: buying criteria for transactional email
Measure your email volume first. Under 1,000/month: free tiers of SMTP2GO, Postmark, or Resend all work — pick on API preference. 10,000-100,000/month: compare Basic/Starter tiers carefully. Postmark Basic at $15/mo caps at 10k with $1.80/1k overage — the most expensive overage rate. Mailgun Basic at $15/mo is similar but with lower overage ($1.10-1.80). SMTP2GO Starter at $10/mo is the cheapest paid entry. Resend Free at 3,000 emails is the most generous free tier. Above 100k/month, Resend's Scale pricing is dramatically cheaper than competitors — worth switching for.
