Tool profile
Developer focused email API for transactional messages with modern SDKs, webhooks, and React templates.
Product transactional mail: receipts, magic links, notifications
Resend focuses on product emails: REST API, SMTP relay, official SDKs, React Email integration for templating, and observability via webhooks (delivered, bounced, opened, clicked). Multi-region sending and strong deliverability positioning target SaaS teams migrating off legacy ESPs.
The free tier allows 100 emails per day with one custom domain and limited webhooks (resend.com/pricing). Transactional Pro is $20 per month for 50,000 emails with no daily cap, more domains and webhook endpoints, and team seats per the pricing table. A December 2025 changelog documents pay-as-you-go overages on paid plans (example invoice shows Pro at $20 plus about $0.90 per additional 1,000 emails in two 1,000-email buckets). Dedicated IPs list around $30/month as an add-on for high-volume senders.
Resend competes with SendGrid, Mailgun, Postmark, and AWS SES on price per thousand and deliverability features. Choose Resend when developer experience and React-centric templates matter; choose SES when raw cost and AWS integration dominate.
Quick fit
Editorial take
Resend’s moat is DX and template workflow, not the lowest cent per email—SES undercuts on pure commodity blasts. Turn on pay-as-you-go overages consciously for seasonal spikes; buckets round up per 1,000 emails. Compare Postmark for deliverability reputation, Mailgun for combined marketing APIs, and SES for AWS-native cost. Warm up dedicated IPs if you add the $30/mo option.
