Email authentication and deliverability: It's more than MailChimp

In 2024, Google and Yahoo have instituted more stringent email requirements for senders who wish their email to be delivered to Gmail or Yahoo Mail accounts. Failure to meet these requirements is expects to result in email not being delivered.

We will review the changes at Google and Yahoo, discuss how correctly implementing authentication and monitoring standards (and adhering to good email sending behavior) is required to ensure deliverability to Gmail and Yahoo Mail (and likely other email services).
