Resend and SendGrid are both email APIs: your code calls them, and they deliver each email to the inbox. Resend launched in 2023 from the team behind React Email. SendGrid, part of Twilio since 2019, sells email marketing as a separate product.

Need a complete notification engine around Resend or SendGrid? Choose SuprSend
SuprSend is an agentic notification platform that sits above your email provider. It decides whether a message goes, on which channel, when and to whom, and retries through the other provider if the first does not confirm delivery. Tenants, workflows, translations and preferences are built in, and the same trigger can also reach push, SMS, WhatsApp, Slack and an in-app inbox. Resend and SendGrid deliver the email you hand them; the logic around it stays in your code.

FAQ
Is Resend better than SendGrid?
ResendResend is better for developers who want React templates, a free tier that does not expire, 30 days of email data on every plan, and an MCP server agents can send through.
SendGridSendGrid is better for senders who want a dedicated IP included on Pro, address validation, subusers for each client, and EU data residency from one vendor.
Which is cheaper, Resend or SendGrid?
At 50,000 emails a month they are within a nickel: Resend Pro is $20 and SendGrid Essentials is $19.95. Above the plan, Resend charges $0.90 per 1,000 and SendGrid Essentials 50K $0.0013 per email, so Resend is cheaper on the overage. With a dedicated IP, SendGrid Pro at $89.95 is cheaper than Resend Scale at $90 plus $30.
How do I move from SendGrid to Resend?
Verify your sending domain in Resend, swap the SendGrid SDK or SMTP settings for Resend’s, rebuild dynamic templates as React Email or Resend templates, point webhooks at the new events, and carry over your suppressions. Resend publishes a SendGrid migration guide.
Can I use Resend and SendGrid together?
Yes. You can verify the same domain with both and choose the vendor per message in your code. SuprSend, which publishes this page, does that routing for you: it sends through one and falls back to the other if a send fails, with no code change to switch.
