DKIM is specified in RFC 6376, and it is used by a number of email service providers, including Google, Yahoo, and Microsoft. DKIM is designed to address some of the flaws in the existing email system, such as spoofing, phishing, and message tampering. It allows email senders to digitally sign their messages in a way that can be verified by email receivers. This allows receivers to verify that the message truly came from the sender, and has not been tampered with.
How to Configure DKIM for Constant Contact
You must publish two TXT records in your domain’s DNS in order to configure DKIM.
To self-authenticate, your custom domain, send an email to Constant Contact’s account review and deliverability team.
Let them know which domains you wish to set up DKIM for, and Constant Contact’s customer service team will respond with your DKIM keys.
Additionally, you will receive a letter with the TXT record syntax that you must publish in your DNS to set up DKIM for Constant Contact.
Now you have two options for publishing the TXT records: either ask your domain administrator for assistance or manually log into your DNS administration console and publish the entries in the appropriate section.
