How to Set Up DKIM for Namecheap?

October 11, 2023  |  2 min read

DKIM uses cryptographic signatures and public-key infrastructure to verify that an email message has not been altered during transit and that it truly came from the claimed sender. Email senders can use DKIM to sign their messages by adding a DKIM-Signature header field to the messages. Email receivers can then use the public key published in the DNS to verify the signature and check that the message has not been tampered with. 

How to Set Up for Namecheap DKIM Setup 

  • Open your Namecheap account and log in.
  • Click “Manage” after selecting your domain from the Domain List.
  • Click on “Advanced DNS”
  • There is a DNS section there where you can add a new record.
  • Click “Add New Record”
  • The new DKIM record should be added after: Select the TXT record type and the hostname s1.domainkey, where s1 is your DKIM selector. Add the value of the produced record to the Value column now.
  • Click on “Save All Changes”
