Business Catalyst End of life announcement - find out more details.

DMARC stands for “Domain-based Message Authentication, Reporting & Conformance”. It is an email authentication protocol that instructs receiving servers to either bounce or receive incoming e-mail that fails SPF or DKIM authentication.

This should prevent phishing, spoofing, and the delivery of fraudulent emails. Strict DMARC policies however can also misidentify your emails as fraudulent.

Changes In DMARC

Google, Yahoo and AOL have modified parameters in their DMARC settings, so that now, e-mail sent on behalf of Gmail, Yahoo or AOL accounts will no longer be received.

What does that mean for you?

As a Business Catalyst user, these DMARC changes mean that you should no longer set Gmail, Yahoo or AOL addresses as "From Email" for:

  • System E-mails: Workflow notifications or Auto-responders
  • E-mail Campaigns

Why? Because doing so will cause those e-mails or newsletters to be automatically rejected by any receiving emails servers that are DMARC compliant.

Important: Email rejected on account of this change will completely bounce, they will not even reach the Junk/Spam folders.

What can you do?

All you need to do is make sure you use any accounts Other than Gmail, Yahoo or AOL when setting up any "From Address" in Business Catalyst.
