I am trying to get the DMARC and SPF records to work and I must be doing something wrong. Any chance someone has done this on Amazon Route 53 and could give me an example of getting the records to work there?
The SPF Records should include HubSpot, your email provider and any other neccessary hosts.
The DMARC is simpler, and sets the policy to accept or reject the DKIM rules.
If you send me a message with your domain name I can have a look and make some recommendations.
