Google is killing one of Gmail’s most useful power-user features

Credit: Stephen Headrick / Android Authority TL;DR Starting January 2027, Gmail will no longer support sending emails from third-party addresses (such as Yahoo, Outlook, or custom personal domains) via web or mobile apps. The change also eliminates Gmailify and web-based POP mail fetching. However, native Gmail mobile app multi-account support, Gmail-to-Gmail aliases, and Google Workspace “Send as” options will remain unaffected.
