Resend vs SendGrid
Resend is what you reach for when you’re shipping a product. SendGrid is what you fight with when you inherit one. Pricing, DX, deliverability, React Email and the case for both.
For any new product in 2026, pick Resend. The API is clean, React Email makes templates a joy, deliverability is now genuinely competitive with the incumbents, and the pricing is honest. SendGrid only stays in the picture for huge sender volumes (millions per day), heavy marketing-team use of the visual editor, or migrations that aren’t worth touching. For developer-built transactional email — the most common case — it’s not even close.
You're a developer, you ship transactional email, you want React Email components, and you want a pricing page you can read in one breath.
You're sending millions of emails a day, your marketing team uses the drag-and-drop editor, or you're already integrated and migration cost outweighs benefit.
Side-by-side, line by line
Both services do the same fundamental thing: get an HTML email reliably into someone’s inbox. The differences are everywhere else.
| Feature | Resend | SendGrid |
|---|---|---|
| Free tier | Edge3,000 emails/month, 100/day. No credit card. | 100 emails/day forever. Adequate for hobby use. |
| Pricing entry-level | $20/mo for 50,000 emails. Predictable. | Essentials $19.95/mo for 50,000 emails. Comparable. |
| Pricing at 1M/month | Edge$90/mo (Pro 100k) + per-additional. Around $200/mo. | Pro plan ~$249/mo (1M sends, less marketing tooling). |
| API design | EdgeModern REST + idiomatic SDKs. Clean as anything. | Functional. Older. The legacy shows in places. |
| Templates | React Email components. Type-safe, reusable, lovely. | Visual drag-and-drop editor + Handlebars syntax. Good for marketers. |
| Deliverability | Excellent and now well established. Same backbone class. | Excellent — it's their reputation moat. |
| Domain setup | EdgeDNS instructions are clear, verification under 30 seconds. | Works fine, more steps, more legacy options to confuse. |
| Webhooks | EdgeBounces, delivered, opened, clicked, complained. Clean payloads. | All the events. Slightly more verbose payloads. |
| Marketing campaigns | Audiences and Broadcasts. Genuinely good for a transactional-first tool. | EdgeFull marketing suite — segmentation, A/B, automations. |
| Inbound parse | Available. Webhooks parse incoming mail to JSON. | Available. The classic feature. |
| Batch / bulk send | Resend Batch API: 100 emails per call. Plenty for transactional. | EdgeDesigned for high-volume marketing send. |
| Vendor confidence | EdgeIndependent, focused, well-funded. | Owned by Twilio. Long-term direction tied to Twilio strategy. |
Resend
- React Email is the best email templating story since MJML.
- API is genuinely a pleasure. SDKs are typed, examples are clean.
- Deliverability has caught up — well-established now.
- Pricing is one screen, no hidden bands or "talk to sales" until very late.
- Domain verification is the smoothest in the industry.
- Founders are responsive — issues actually get fixed.
- Marketing automation tooling is light if your marketers want bells and whistles.
- Smaller ecosystem of plugins and integrations than the incumbent.
- No built-in IP warming for big-bang migrations from another provider.
- Younger company — some enterprises will need to do extra diligence.
SendGrid
- Battle-tested at literally web-scale volume.
- Marketing Campaigns module is mature — segments, A/B tests, automations.
- Twilio integration if you also do SMS / WhatsApp at scale.
- Plenty of pre-built integrations into Salesforce, HubSpot and the rest.
- Reputation moat — IP pools that have decades of history.
- API and dashboard show their age. Documentation is sprawling.
- Pricing for marketing-heavy plans gets eye-watering quickly.
- Twilio ownership means roadmap doesn't always serve email-only customers.
- Account suspensions for new senders are notoriously aggressive.
- Templates are fine but Handlebars-in-the-UI is not 2026 DX.
Resend
- You're a developer building transactional email for a SaaS or product.
- You want React Email components instead of HTML email tables.
- You ship under ~5M emails/month and predictable pricing matters.
- You want fast domain setup and a clean API on day one.
- You're running on Next.js, Remix or anything modern.
- You're a small team that values DX and time-to-first-email.
SendGrid
- You're sending tens of millions of marketing emails a month.
- Marketers — not engineers — own the email programme day to day.
- You're already integrated with Twilio for SMS / WhatsApp.
- You need very mature marketing automation, segmentation and reporting.
- You've got an inherited stack and migration cost outweighs the upside.
- Enterprise procurement requires a vendor with decades of paper trail.
What I install on day one
For every Next.js or SaaS project I’ve started in the last 18 months, the email stack is Resend + React Email + a single typed sendEmail() helper. It takes around 20 minutes from "create account" to "transactional email in production". The React Email piece is the killer — emails are real components, you can preview them in dev, and they don’t require an HTML-tables specialist to maintain.
I’ve migrated three clients off SendGrid in the last year. In all three cases the triggers were the same: pricing creep, dashboard friction for the dev team, and the desire to move email templates into source control alongside the rest of the code. None of them have looked back, and deliverability has been stable or better since the move.
That said, I wouldn’t move a marketing-team-led email programme onto Resend tomorrow. SendGrid (and frankly Customer.io or Loops) is still better for a non-technical user who lives in the email tool day to day. If your marketers need drag-and-drop visual editing, segments and A/B tests, the calculus is different. Use Resend for transactional, something else for marketing — that split is a perfectly sensible architecture.
The honest conclusion
Resend is what email APIs should have looked like ten years ago. SendGrid is fine, but "fine" doesn’t cut it when the alternative is genuinely a better tool. Pick Resend by default for transactional. Keep SendGrid in mind only when volume, marketing tooling or institutional inertia gives you a real reason.
Still not sure which to pick?
