Make ActiveCampaign DMARC-compliant
How to authenticate ActiveCampaign as a sender on your domain - so its mail passes SPF, DKIM and DMARC, and you can safely reach enforcement.
Three steps to authenticate ActiveCampaign
ActiveCampaign needs to pass SPF and DKIM, and align with your domain so DMARC passes. Here’s how – confirm the exact values against ActiveCampaign’s current documentation as you go.
How ActiveCampaign authenticates
Set up the ActiveCampaign 'Mailserver Domain' CNAME, which lets ActiveCampaign serve the SPF record on your behalf - you don't add an include to your own record.
So there’s no SPF include to paste in for ActiveCampaign – DKIM (next step) is what carries DMARC alignment. Hosted SPF still helps keep your overall record under the 10-lookup limit.
No SPF include to add
ActiveCampaign authenticates through the CNAME records you publish during its domain-setup flow – follow Step 2.
Turn on DKIM signing
DKIM cryptographically signs each message so receivers can prove it really came from you and wasn’t tampered with. Use ActiveCampaign's sending-domain setup ('Configure Domain' does it automatically, or 'Set up manually' walks you through it) to publish DKIM.
DKIM is what keeps you authenticated even when a message is forwarded – so it’s worth getting right. More on how DKIM works →
- Enable DKIM inside ActiveCampaign
- Publish the DNS records it gives you
- Wait for it to verify, then send a test
Confirm alignment, then enforce
With SPF and DKIM set up, check that ActiveCampaign aligns – that the authenticated domain matches your visible From address. Once every legitimate sender aligns, you can move DMARC to p=reject safely.
DMARCER’s enforcement journey shows you exactly when it’s safe to advance – no guesswork.
Good to know
Gmail and Yahoo have required DKIM + DMARC for bulk senders since 2024 - don't skip them.
