User Permissions Needed
To restrict user email domains:
Manage Users
From Setup, in the Quick Find box, enter Allowed Email Domains, and
then select Allowed Email Domains.
Note If you don’t see this page, enable the allowlist. For more information, see Enable the
Email Domain Allowlist.
Click New Allowed Email Domain.
Enter a Domain.
You can enter a top-level domain, such as sampledoc.org, or a
subdomain, such as emea.sampledoc.org.
Click Save.
You can repeat the steps to add more email domains to the allowlist.
After you've added one or more email domains, the Email field for each
new user must match an allowed domain.
The Email field for existing users doesn’t have to comply with the
allowlist. However, if you edit an existing user, update the Email field to
match an allowed email domain.
Note The email domain allowlist doesn't apply to users external to your org, such as portal,
Experience Cloud site, or Chatter External users.
