GMails custom domain "send as" discontinues January 2027

Google will discontinue Gmail’s "Send as" support for third-party email addresses (for example, Yahoo or Outlook) in January 2027, while preserving Google Workspace aliases and other Gmail addresses. For IT organizations, this reduces flexibility for users who rely on Gmail as a unified sending platform for non-Google accounts, and it may require policy updates, workflow changes, and migration planning for email identity management, especially in environments with BYOD, consultants, or multi-domain communication needs. CIOs should assess where this feature is embedded in business processes now so they can avoid disruption and ensure email branding, user experience, and compliance controls remain intact.
