Constant Contact Email Authentication

[ojcapps]

Why would I want to use Constant Contact Email Authentication over utilizing their DKIM setup?  Would using it drop our risk of blacklisting from the Constant Contact bulk mail server sends?

Hello @ojcapps ,

Self-authentication, if you have your own domain, will generally have the best deliverability rates. Authenticating through us is advised for those with free email address accounts (Gmail, Yahoo, Live, etc.) that aren't able to utilize a DKIM setup.

If you'd like to discuss your options further, or if you need assistance getting self-authentication setup for your CTCT account, I'd recommend speaking directly with our Deliverability team.
