With all the new email authentication updates that just happened, I’m wondering if it’s best to use another domain to send email from other than my primary domain. I understand that it can be better so your primary domain doesn’t get blocklisted from spam.
Just wanted to see what others are doing to better their email authentication?
I got a good response on Slack from the same question that I wanted to share here and that is to use the same domain. And if your sending from say MS Office365 and Hubspot wants you to add their domain to the SPF file, just added another include with Hubspots domain to the SPF record and that will authenticate your email in both Outlook and Hubspot.
Instead of adding new records, you want to string the SPFs all in the same record between “include:” and “-all”, for example:
“v=spf1 include:spf.protection.outlook.com; 5189079.spf10.hubspotemail.net - all”
