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 Configure DKIM for Active Campaign?

• Navigate to “Settings.”
• Select “Advanced.”
• Select “I will handle my own email authentication” from the menu.

• In the DKIM area, enter the domain name for which a TXT record has to be created, and then click “Generate.” 

Your domain will generate the following DKIM TXT Record Name and Value:

• DKIM records should be copied to your keyboard.
• Put the DKIM records (resource type: TXT; name/host: ._domainkey.mail.example.com) in your DNS. then save your modifications.
• Wait a while for these modifications to take effect on your DNS (it can take up to 24-72 hours depending on your DNS hosting provider)

Please note that the domain name, DKIM selector, and DKIM record values should be replaced with those created for your domain.
