Hello,
I have accidentally deleted my SPAM mail in Gmail however later I come to know that one of my important mail marked as spam. Could you please help me to recover those mails. I have already checked the Trash and it does not have.
When a message is delete, it will stay in the Trash during 30 days. After this delay, the message will be permanently deleted and it will be impossible to recover it.
If Gmail has not deleted the messages from the server, you can still recover deleted emails after deleting them from your trash folder.
Click in the searchbox and type
in:trash
to show all deleted emails.
Then right-click on the message and choose "Place into inbox" or check the message and choose "Move to..." and then Inbox.
