Google is ending support for the "Send as" feature that allows users to send emails from external services like Hotmail, Yahoo, and Outlook as well as custom domains using their primary Gmail account. According to Google's support document, "Send as" will be discontinued in January 2027 for Gmail's web and mobile app interfaces. You'll still be able to add third-party accounts on mobile, meaning you can check your email on iOS or Android, but not send messages from those aliases. (Third-party accounts won't sync at all on the web.) Switch to a desktop mail client insteadIf consolidation is your goal, your best bet is likely to switch to a desktop mail client and connect your third-party accounts via IMAP/SMTP.
