Office 365 - Approve Campaign Monitor to Send Email from My Domain
This document will provide the steps necessary to set up custom domain authentication for Campaign Monitor, approving Campaign Monitor to send email from addresses in your organization's subdomain (e.g. mydomain.wisc.edu).
Note: approving a third-party email vendor to send email as/from @wisc.edu addresses (e.g. email@example.com) is not permitted. Only approve third-party email vendors to send email as/from addresses in your subdomain (e.g. firstname.lastname@example.org).
Campaign Monitor provides publicly available documentation on setting up custom domain authentication.
