If your Yahoo emails disappeared from inbox, it can be due to accidental deletion, filters moving messages to other folders, syncing issues, or even suspicious account activity. Start by checking Trash, Spam, and Archive, then review your filters and account settings. For bulk recovery or migration to a safer platform, you can use the Corbett Email Backup Tool, which automatically downloads and secures your Yahoo emails to your computer or other accounts, ensuring you never lose important messages again.
