Licensing for DKIM/DMARC

Copper Contributor

Is anyone aware of what licensing tier is required for DKIM/DMARC implementation? We are currently licensed with G3. I'm trying to determine if these services are available to my organization, under our current licensing. All I can find are instructions on how to implement and it appears to be a "free" service with O365 licensing. Any help is greatly appreciated. TIA.

If you have Exchange Online, you can use it. There are no other license requirements AFAIK
Thank you for the quick reply, much appreciated.
