Cloudflare
Verify your domain on Cloudflare with Resend.
Add Domain to Resend
Login to your Resend Account and add a domain.
It is a best practice to use a subdomain (updates.example.com) instead of the root domain (example.com). This allows for proper reputation segmentation based on topics or purpose (e.g. transactional and marketing).
Login to Cloudflare
Login to your Cloudflare account and go to the DNS Records of your domain.
Add MX SPF Record
Click “Add Record” on Cloudflare.
Add the MX Record from your domain in Resend to Cloudflare and click “Save”.
Below is a mapping of the record fields from Resend to Cloudflare:
| Cloudflare | Resend | Example Value |
|---|---|---|
| Type | Type | MX |
| Name | Name | send |
| Mail Server | Value | feedback-smtp.us-east-1.amazonses.com |
| Priority | Priority | 10 |
Omit your domain from the record values in Resend when you paste. Instead of
send.example.com, paste only send (or send.subdomain if you’re using a

Do not use the same priority for multiple records. If Priority 10 is already
in use, try a number slightly higher like 11 or 12.
