Editing Email Authentication (section)

=== Authentication Methods ===
There are three established methods used to verify a sender's identity: SPF, DKIM, and DMARC. Starting in February 2024, Gmail and Yahoo will require DKIM and DMARC authentication to achieve delivery. Other mailbox providers already expect senders to authenticate their email traffic. Therefore, ActiveCampaign highly recommends all senders set up DKIM and DMARC.

With ActiveCampaign, you have two options for DKIM, DMARC, and SPF authentication when adding a sending domain:
* If you use the “Configure Domain” option, DKIM, DMARC, and SPF authentication will be set up for you.
* If you choose the “Set up manually” option, we will walk you through the configuration of DKIM, DMARC, and SPF authentications.
