How to Verify your Domain and Create an API Key in Resend ?


Step 1 - How to verify your domain.

A domain is used to send emails using your own domain. Verifying a domain is a required step because it’s essential to ensuring the deliverability of your emails. 

In order to verify a domain, you must set the DNS entries that grant us permission to send email on your behalf.


  1. Navigate to 'Domains' on the sidebar.

  1. Click 'Add Domains'.

  1. Now Enter your Domain and Select the Region.

  1. Now Access the DNS settings page of your DNS provider and add all the following DNS records to the records section. Once all are added, Click the ‘Verify Records’ button above.

Understand a domain status

Domains can have different statuses, including:

Pending: Resend is still trying to verify the domain.

Verified: Your domain is successfully verified for sending in Resend.

Failure: Resend was unable to detect the DNS records within 72 hours.

Temporary Failure: For a previously verified domain, Resend will periodically check for the DNS record required for verification. If at some point, Resend is unable to detect the record, the status would change to “Temporary Failure”. Resend will recheck for the DNS record for 72 hours, and if it’s unable to detect the record, the domain status would change to “Failure”. If it’s able to detect the record, the domain status would change to “Verified”.
