Add Domain to Resend

First, log in to your Resend Account and add a domain. Domain Details
It is best practice to use a subdomain (updates.example.com) instead of the root domain (example.com). Using a subdomain allows for proper reputation segmentation based on topics or purpose (e.g. marketing) and is especially important if receiving emails with Resend.

MX record will differ depending on your selected sending region.
Do not use the same priority for multiple MX records. If Priority 10 is already in use, try a higher value such as 20 or 30.

​
Receiving Emails

If you want to receive emails at your domain, toggle the “Receiving” switch on the domain details page. Enable Receiving Emails for a verified domain
When you enable Inbound on a domain, Resend receives all emails sent to that specific domain depending on the priority of the MX record. For this reason, we strongly recommend verifying a subdomain (subdomain.example.com) instead of the root domain (example.com). Learn more about avoiding conflicts with your existing MX records.
Add an MX record for receiving:
  1. Click the Add Record button.
  2. Hover over the MX Record section and click ADD.
  3. Enter inbound (or your receiving subdomain) in the Host field.
  4. Copy the MX Value from Resend into the Points to field.
  5. Enter 10 for Priority.
  6. Click Add Record to save.

After verifying your domain, create a webhook to process incoming emails. For help setting up a webhook, how to access email data and attachments, forward emails, and more, see our guide on receiving emails with Resend.

​
Complete Verification

Now click Verify DNS Records on your Domain in Resend. It may take up to 72 hours to complete the verification process (often much faster). DNS updates at DreamHost can take several hours to propagate.

​
Troubleshooting

If your domain is not successfully verified, these are some common troubleshooting methods.
Review the records you added to DreamHost to rule out copy and paste errors. Ensure the Host field uses only the subdomain (e.g., send or resend._domainkey) and that you did not include the full domain name.
