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). This allows for proper reputation segmentation based on topics or purpose (e.g. transactional and marketing).

  3. Copy the MX Value from your domain in Resend into the Value field.
  4. Be sure to include the 10 in the Value field, as seen in the screenshot.
