Resend
Transactional email API for developers.
What it is
Resend is a transactional email API aimed at developers, with a clean SDK and React-based email templates. It is built for the case where email is part of the product: sending is an API call, and templates are components rather than a drag-and-drop editor. That makes it a poor fit for marketing teams who need to compose campaigns without a developer.
Resend pricing
Resend publishes 2 plans. Paid tiers start at $40/mo, and a free tier is listed alongside them.
| Plan | Price | What the vendor’s page says |
|---|---|---|
| Free | $0/mo | Free $0: 3,000 emails/month, 100/day, 3 domains, 30-day retention |
| Pro | $40/mo | Enterprise custom for 3M+ emails; marketing: Free 1,000 contacts, Pro $40–$650/month for 5,000–150,000 contacts |

Pick it or skip it
Pick Resend if
- Developers sending transactional email from code — 3,000 emails a month are free with 3 domains
- Products around 50,000 emails a month for $20 (Pro) with 10 domains and no daily cap
- Teams that also want marketing sends priced by contacts: Free covers 1,000 contacts
Skip it if
- You send more than 100 emails a day on Free — that daily cap is the trigger
- You need a dedicated IP or SSO on a small plan: both are Scale add-ons ($30 and $150/month)
- You are above 3 million emails a month and need a negotiated contract
Our verdict
A pleasure to integrate. For high-volume marketing sends, an established ESP still has the edge.
