Microsoft 365 - Approve SendGrid to Send DMARC-Compliant Email from My Domain
This document will provide the steps necessary to set up custom domain authentication for SendGrid, approving SendGrid to send DMARC-compliant email from addresses in your organization's subdomain (e.g. mydomain.wisc.edu).
Information about the protection of UW-Madison email with DMARC can be found here: Email Authenticity
Note: approving a third-party email vendor to send email as/from @wisc.edu addresses (e.g. mynetid@wisc.edu) is not permitted. Only approve third-party email vendors to send email as/from addresses in your subdomain (e.g. account@mydomain.wisc.edu).
SendGrid provides publicly available documentation on setting up custom domain authentication:
https://sendgrid.com/docs/ui/account-and-settings/how-to-set-up-domain-authentication/
Note: A CNAME record is an alias for another domain. You should never create a CNAME record for an existing UW-Madison email domain (e.g. doit.wisc.edu).
If you need assistance in taking the above steps, please contact the DoIT Help Desk.
