Gmail emails disappeared from Inbox? Here’s how to fix it. First, check Trash. Emails stay there for 30 days. Then check Spam. Gmail may misplace them. Next, look at All Mail for archived messages. Don’t forget the Social and Promotions tabs. Gmail often moves emails there. Use Gmail’s search bar to type names or subjects. If nothing works, clear browser cache or use a new browser. To avoid data loss, always back up your Gmail account. Backups keep your emails safe and easy to restore.
