One of the most popular e-mail boxes is Gmail developed by Google. This mailbox is characterized by good spam filtering and the lack of unnecessary ads in the mailbox that appear on many competing portals. However, in recent days there has been a bug in the spam filter used in Gmail.

Many users have complained on Twitter and Reddit about Gmail problems in recent days. Unexpectedly, normal non-spam messages were sometimes marked as spam, making it difficult to see. Users didn't receive information about their receiving, but as Google informed, this problem has already been resolved. If you use Gmail, it's a good idea to check the spam messages received in recent days so that important messages wouldn't be deleted from your accounts.
