Gmail is a free email service developed by Google. Users can access Gmail on the web and using third-party programs that synchronize email content through POP or IMAP protocols. Gmail started as a limited beta release on April 1, 2004 and ended its testing phase on July 7, 2009.
Glidiany V. says, "Less storage with Gmail than with Yahoo Mail and hard to filter out messages by sender only way is labels but not very efficient. Old yahoo allowed filtering out by sender easily to organize by sender and delete multiple messages."
