After Spring ’25, to comply with increased email security standards, users are required to verify the Email Address in My Email Settings
Where: This change applies to Lightning Experience and Salesforce Classic in all editions except Database.com
When: Salesforce enforces this update in Spring ’25. To get the major release upgrade date for an instance, go to Trust Status, search for this instance, and click the maintenance tab
Why: A verified email address is used to send emails from your account. This update allows increased accountability and security for email deliverability
How: To comply with increased email security standards, emails fail to send from the return email address in My Email Settings until the address is verified. All users must visit their My Email Settings and manually verify their email addresses by selecting Resend Verification Email and clicking the link in the email. If the resend option is unavailable, the return address is already verified. Users receive a verification email once per release until Spring ’25. The email includes the verification link
