Enable users whose email domains you can’t verify—such as users with public email addresses, consultants, and site users—to send email from Salesforce. With your substitute email address, the user’s display name remains unchanged, but the From address uses an organization-wide email address or an email address that ends with .sfcustomeremail.com. This option also applies to system-generated emails and emails sent via shared email accounts with an unverified domain.
Where: This change applies to Lightning Experience and Salesforce Classic in all editions except Salesforce Free Suite and Database.com. This change has no impact on trial orgs.
When: Salesforce plans to make these changes June 23–July 3, 2026.
- Enable the “Use a substitute email address for unverified domains” Deliverability setting in all orgs.
- Add an option to select an organization-wide email address as the From address for emails sent for users with an unverified email domain.
Why: Consultants, Experience Cloud site users, and Salesforce Site users often have email domains that you can’t add to your verified list. And you can’t verify the domains for public email addresses, such as yahoo.com. When you enable this feature, those users can send email from Salesforce while preserving their display names.
How: From Setup, in the Quick Find box, enter Deliverability, and then select Deliverability. Select Use a substitute email address for unverified domains (1). For Substitute Email Address (2), select the organization-wide email address to use as the From address.
If no substitute address is specified, Salesforce sends the email from
email@UniqueId.sfcustomeremail.com, where
UniqueId is your org ID or Experience Cloud site ID.
