Prevent Reps from Emailing Customers Who Don’t Want Commercial Emails
Where: This change applies to Lightning Experience and Salesforce Classic in Essentials, Professional, Enterprise, Performance, Unlimited, and Developer editions.
Who: Reps with the Send Non-Commercial Email permission can send non-commercial email. This permission is already enabled for all standard profiles that send email and for already-created custom profiles.
How: You must have the Email Opt Out field or Email Privacy enabled for this setting to take effect.
To prevent a rep from sending email to customers who have Email Opt Out or the Don’t Market email privacy setting, disable Send Non-Commercial Email in their permission set.
