Resend vs SMTP2GO
Comparing pricing tiers, deliverability architectures, and feature support for transactional and marketing senders.
Editorial Verdict
SMTP2GO is pragmatic relay: anycast SMTP + API, 1,000 free emails/month, $15/mo incl 10k, Professional bundling a dedicated IP at $75/mo. Resend is developer-first: React Email, modern SDKs, 3,000 free sends, $20/mo incl 50k. Volume-for-volume Resend usually costs less until SMTP2GO’s Professional tier; feature-wise it depends whether you want authoring ergonomics (Resend) or relay flexibility + included IP (SMTP2GO).
