Google has sent a notice to some users of its Gmail service letting them know a recent bug may have caused some of their messages to be incorrectly categorized.
The bug occurred when users deleted emails or marked certain emails as spam. Gmail would apply those actions to messages other than the ones users were trying to delete or send to their spam folder.
Google said the error occurred from Jan. 15 to Jan. 22 and has since been fixed.
"We encourage you to check your Trash and Spam folders before Feb. 14 for any items you did not intend to delete or mark as spam and move them back to your inbox," the notice said. "We apologize for any inconvenience."
It's unclear how many users may have been affected by the bug, but the issue was limited to users of the Gmail mobile app for Apple iOS, the mobile browser version of Gmail and the offline version of Gmail, Google told The Verge.
Google has experienced a number of issues recently with Gmail.
Last week, a software bug made the service inaccessible for about half an hour and even longer for 10% of users. The company also experienced a glitch that inadvertently resulted in one man receiving thousands of emails from numerous Gmail users.
