|---|---|---|
| Free tier | Trial only, no permanent free plan | 3,000 emails/month, 100/day, forever |
| Entry paid plan | $19.95/mo for 50k emails | $20/mo for 50k emails |
| API quality | Functional, older REST API | Modern REST API with typed SDKs |

The Verdict
SendGrid is the safer pick if you need marketing campaigns, contact segmentation, and dedicated IPs bundled with transactional email. Resend wins for developers who just need a fast, reliable API to send transactional emails and don't want to pay for features they won't use — its free tier and React Email integration make it the better starting point for small teams and side projects.
How to switch from SendGrid to Resend
- 1Export your contact lists from SendGrid as CSV files via Marketing > Contacts > Export, and pull any Dynamic Templates as JSON using the Template Engine API since there's no bulk template export.
- 2Sign up for a free Resend account and verify your sending domain by adding the provided SPF and DKIM DNS records.
- 3Recreate your email templates using React Email (or plain HTML) in Resend's dashboard or codebase, converting SendGrid's Handlebars-style variables to Resend's templating approach.
- 4Update your backend code to use Resend's SDK (e.g., `resend.emails.send()`) in place of SendGrid's `@sendgrid/mail` calls, mapping API keys and sender addresses.
- 5Test transactional flows end-to-end (signup, password reset, receipts) in a staging environment before cutting over production traffic.
- 6Monitor deliverability and bounce rates for the first two weeks after cutover, then cancel your SendGrid subscription once volume is fully migrated.
SendGrid vs Resend: common questions
How do I export my email templates and contacts from SendGrid?+
SendGrid lets you export contact lists as CSV files from the Marketing > Contacts dashboard. Email templates (Dynamic Templates) can be copied manually via the template editor or pulled via the Template Engine API as JSON — there's no one-click bulk export for templates, so plan to script this with the API if you have many.
What features do I lose moving from SendGrid to Resend?+
You lose the built-in marketing campaign builder, contact segmentation, and dedicated IP options — Resend is transactional-email focused. If your team relies on SendGrid's marketing automation, you'll need a separate tool (like Loops or Customer.io) alongside Resend.
Is Resend's free tier enough for a small team?+
For most small SaaS apps sending signup confirmations, password resets, and notifications, 3,000 emails/month is enough — that's roughly 100 emails/day. If you're sending marketing newsletters or have thousands of active users, you'll outgrow the free tier and move to the $20/mo plan for 50,000 emails.
Does Resend integrate with the tools I already use?+
Resend has official SDKs for Node.js, Python, Ruby, PHP, Go, and Java, plus native integration with React Email and Next.js. It has fewer no-code integrations than SendGrid (no direct Zapier app as of now), so most integrations require writing a small amount of code.
Will Resend actually cost less than SendGrid over time?+
At equivalent volume (50k emails/month), pricing is nearly identical — $19.95 vs $20/mo. The real savings come if you're a small sender: Resend's free tier covers 3,000 emails/month at $0, while SendGrid requires a paid plan or trial once you're past onboarding.
