How to check if my domain is authenticated

[AMcCabe6]

Hey, 

I got a notification telling me that emails will need to be sent for authenticated domains soon, and followed the steps provided within Hubspot's doc in which it explains how to add DKIM, SPF and DMARC - https://knowledge.hubspot.com/email/overview-of-email-authentication 

Does anyone know if there is a way to double check that this has all been set up and is working correctly before any changes kick in in February 2024?

Hi @AMcCabe6,

MXToolbox is a tool that can help you check whether everything is set up correctly:

Best regards!

I already have  DKIM setup with our M365 tenant which would conflict with the HubSpot provided CNAME entries. Is it possible to authenticate a single domain multiple times, maybe by setting up a custom DKIM selector and adding it to the domain as a custom subdomain? Thanks!
