How to Set UP DKIM for Sharpspring?

October 11, 2023  |  < 1 min read

DomainKeys Identified Mail (DKIM) is an email authentication system designed to detect email spoofing. It allows organizations to take responsibility for transmitting a message, while providing a mechanism to verify that the message was not altered during transit.  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. 

Steps to Configure DKIM for Sharpsping

  • In the top toolbar of SharpSpring, select Menu > Settings.
  • On the left side, under Features, select Company Email Settings.
  • Select the DKIM & Sending Domains tab.
  • Confirm your domain.
  • As soon as your domain has been confirmed, click Set Up DKIM.
  • Select Get My CNAME Settings at this point.
  • Add the CNAME records for your domain that Sharpspring produced. The types of CNAME records that Sharpspring offers are as follows:

s1._domainkey and s2._domainkeyDKIM authentication hostnames
