Resend
Resend is a developer-first transactional email API — a newer brand in the transactional segment whose raw search volume we discount because the word doubles as a generic verb. resend.com served the developer email API homepage directly when we verified it in August 2026.
The transactional Pro plan includes exactly 50,000 emails per month for $20 — tied with Mailtrap for the cheapest USD tier passing our functional checks (custom domain plus webhooks) at that volume — with opt-in overage at $0.90 per 1,000. A free plan sends 3,000 emails per month under a 100-per-day cap. Pricing checked 19 August 2026. The curve steepens beyond Pro's range: Pro scales to 100,000 emails at $35/month, but 500,000 emails requires Scale at $350/month, moving Resend from a cheapest-tie at 50,000 emails to above the category median at the top volume (multi-volume capture, 21 August 2026).
Deliverability: not yet tested. A measured seed-list cycle for Resend is planned as part of our catalog rollout — see how we test for the protocol and the email deliverability ranking for services with data.
