Considerations for Using Organization-Wide Email Addresses

Before creating organization-wide addresses and assigning them to your Salesforce user profiles, review a few details, including information about mass emails and reporting.

• You can’t use organization-wide addresses in these instances:
  • Scheduled reports
  • Scheduled 1:1 emails
  • Scheduling dashboards for refresh
  • Sending mail merge emails, mass emails, and meeting requests to contacts and leads
• You can’t delete or change an organization-wide email address when it’s used by an email alert.
• You can create an org-wide email address specifically for No-Reply emails or use an existing org-wide email address as the default No-Reply address. You can have only one verified No-Reply org-wide email address at a time. After a No-Reply address is created, you can’t delete it.
• You can use organization-wide addresses when using Outlook and Gmail integration. If a user’s connected account or sender email address is the same as the org-wide email address, the org-wide email address takes precedence in the From: dropdown. The connected account or sender email addresses aren’t available.
• The org-wide verified email address is used as the From address in emails sent from the guest user record, such as emails sent from some custom flows. Outgoing emails are blocked when they're sent from an unverified address in the guest user record.
• You can't see the Reply, Reply All, and Forward standard quick actions on an Email.Message record if the sender's email address is an organization-wide address that isn't set for User Selection and Default No-Reply Address. Manage this setting in Organization-Wide Addresses in Setup.
• Use an email address in your own domain for new organization-wide email addresses. Existing addresses that use email services continue to work, but we recommend migrating them to your own domain to avoid potential issues. Email services include Email-to-Case, Email to Salesforce, and the Apex email service.
• An admin can create an org-wide No-Reply address or use an existing address without requiring verification. Each time a new org-wide email address is verified, it replaces the previously verified one.
  

  Note An admin verifies a new org-wide email address by clicking the link in the email sent after creating the address.
