Self-Authentication and Subdomains to send Newsletters


We have updated our DNS records for self-authentication and it's been 48 hours I think and it is still pending.


Also, to help prevent our newsletters from going into spam/junk folders, we would like to set up a subdomain. How do we do that and where in Constant Contact do we put that information for the new subdomain?




Hello @JillianM115 ,


I'd recommend going through our main article on setting up / updating self-authentication records for your account. For further, specialized assistance, insight, and troubleshooting, I'd advise speaking with the Delivery team directly.
