Enable Salesforce to send email for users whose email domains you can't verify, such as
Experience Cloud site users, Salesforce Sites users, consultants, and users with public email
addresses like yahoo.com or icloud.com. With this
option, the user's display name and reply-to address remain unchanged, but the From address uses
email@UniqueId.sfcustomeremail.com, where UniqueId is
your org ID or Experience Cloud site ID.

This feature also applies to system-generated emails and emails sent via shared email
accounts, such as organization-wide email addresses, with an unverified domain.
This feature has no impact on email addresses that end in @gmail.com,
@hotmail.com, or @outlook.com, nor on email sent
with Salesforce Free Suite or in trial orgs with the
salesforce-free-mailsend.com domain. For more information, see Requirements to Send Email from Salesforce.
From Setup, in the Quick Find box, enter Deliverability, and
then select Deliverability.
Select Use a substitute email address for unverified domains,
and then save your changes.
When users with an unverified email domain send email from Salesforce, the From
field can show either their Salesforce email address or the substitution email
address.
Example
In our example org, the “Substitute unverified email-sending domains” option is enabled, and
example.com has no active DKIM key and no verified entry on the
Authorized Email Domain list in Setup.
An internal user, Vera Lee, with email address vLee@example.com, verified their email address.
When Vera logs in to Salesforce and uses the Send Email action on a contact, the email
includes these values.
From: "Vera Lee" email@orgId.sfcustomeremail.com
Reply-to: "Vera Lee" vLee@example.com
An Experience Cloud site user, Oscar Jackson, with email address Oscar.Jackson_54@yahoo.com, also
verified their email address. When Oscar Jackson logs in to an Experience Cloud site and
sends an email via the Send Email action on a contact, the email includes these values.
The organization-wide email address for the Support profile is support@example.com with a display
name of Example Support, and an admin verified that email address. When users send email
from the Support profile, the email includes these values.
