Dynamics 365 Marketing domain authentication is a crucial branding step to ensure marketing emails’ high deliverability and create a better user experience with marketing forms. To learn more about Dynamics 365 Marketing domain authentication.

Why authenticate domains?

First of all, we require to ensure that the company domain is branded. Dynamics 365 Marketing provides a pre-authenticated subdomain using dyn365mktg.com, which is generally not accepted by marketers. Example domain provided by Dynamics 365 below.

Besides branding, Dynamics 365 Marketing domain authentication is highly important for the following reasons.

Marketing Emails

Marketing emails get digitally signed when sent out from a system that has the domain authenticated. The authentication ensures that the emails are accepted by the recipient’s mail servers.

Form hosting in company website

When hosting the form at the client’s website, we have to show the ownership relation between the form and the domain name. The form pre-fill feature is not available if the domain is not authenticated.

Add new domain

From the active domain list, we can add as many domains or subdomains, as the business requires to authenticate. For example, if a company has operations in multiple countries and uses a domain in each country. In the US the domain used is companyname.us and in Canada the domain is companyname.ca.

Enable custom Envelope-from domain

The marketing emails have two form email addresses, the normal from address and Envelope From address, or simply the “Return-Path” address. The Envelope-from address can help email deliverability when set.

The Envelope-from domain name is a subdomain of the main domain use and must start with the word “bouncing”. When we enable the custom Envelope-from domain, the Envelop-from domain name will be auto-filled, however can be overwritten.

DNS keys

Once the domain authentication record is saved, the DNS key records will be created. For every enabled domain authentication option, A DNS record key will be generated.

Also, once the domain authentication is saved, the domain name is locked and unchangeable. If we need to change the domain name, we have to delete the record and regenerate the authentication from the beginning.
