Dmarc issue

New Contributor

I need help setting up my DNS as my msil server uses DMARC. I use Marketing free btw.

This is what I get when I try to send marketing mails.

Hi @Bouf


DMARC and DKIM (email sending domains) are not currently supported in HubSpot Marketing Free accounts. If your organization has a DMARC policy in place, you'll want to make sure SPF and DKIM are set to 'relaxed' alignment.
