Resend Email
Setup
npm install resend
npm install @react-email/components
Sending Emails
import { Resend } from 'resend';
import { WelcomeEmail } from '@/emails/welcome';
const resend = new Resend(process.env.RESEND_API_KEY);
// Plain text
await resend.emails.send({
from: 'App <[email protected]>',
to: ['[email protected]'],
subject: 'Welcome',
html: '<p>Your account is ready.</p>',
});
// With React Email template
await resend.emails.send({
from: 'App <[email protected]>',
to: ['[email protected]'],
subject: 'Welcome',
react: WelcomeEmail({ name: 'Alice' }),
});
React Email Templates
Template pattern and webhook handler examples: see REFERENCE.md.
Preview Templates
npx email dev
Domain Configuration
- Add your domain at resend.com → Domains
- Configure DNS records (SPF, DKIM, DMARC) and await verification (<1h)
- Post-verify: send one canned test to
postmaster@and confirm headers (SPF/DKIM pass). - Use
from: 'Name <[email protected]>'in sends
Webhook Handling
Webhook handling patterns and a safe, verified handler example are in REFERENCE.md (this directory).
Quick Verification Workflow
- Add domain and copy DNS records.
- Verify DNS propagation:
dig TXT yourdomain.com— confirm SPF/DKIM records appear. - Send a test email and confirm SPF/DKIM pass in headers.
- Deploy webhook handler; test with:
curl -X POST -H 'Content-Type: application/json' -d '{"type":"email.delivered"}' https://yourapp.com/api/webhooks/resend— assert 200. - If verification fails: re-check DNS, API keys, and webhook secret.
See REFERENCE.md for detailed verification commands and troubleshooting.
