Resend vs SendGrid
A side-by-side comparison from 108 GitHub-verified developers who shipped production code on both platforms.
Resend wins on developer experience and is competitive on deliverability up to ~1M emails/month. SendGrid wins above 1M/mo on per-email cost and operational maturity for enterprise volume. For most teams below 1M emails/month the decision is Resend; above that, the math flips.
Benchmark Comparison
| Metric | Resend | SendGrid |
|---|---|---|
| Developer experience | Best-in-category (React Email) | Dated but functional |
| Free tier | 3,000 emails/mo | 100/day (3K/mo) |
| Cost at 1M/mo | ~$1,500 | ~$900 |
| Deliverability (transactional) | 95-98% inbox | 92-96% inbox |
| Enterprise deliverability support | Smaller team | Mature ops team |
| Marketing campaigns | No | Native (Marketing Campaigns product) |
| Template tooling | React Email — JSX components | Drag-drop builder + handlebars |
| Best fit | Modern stacks, < 1M emails/mo | 1M+ emails/mo, enterprise |
Operational Verdicts
Resend developer experience and deliverability both win. React Email replaces an entire templating pipeline.
SendGrid pricing scales better and the operational ops team handles sender-reputation edge cases at volume better than Resend can today.
SendGrid Marketing Campaigns bundles in. Resend transactional-only; you would add Customer.io or similar for marketing.
