analyzing email metadata of a user to detect an indication of automation comprising:

analyzing the user's email metadata to detect a usage pattern of a sender of email messages, wherein the sender of email messages sends a threshold number of email messages to the user, within a period of time, without receiving a threshold number of email messages;

identifying the sender of email messages as a mail-bot in response to the detected usage pattern;

analyzing the user's email metadata to detect a received email message not explicitly addressed to the user, wherein the received email message not explicitly addressed to the user is received by one or more other users;

identifying the one or more other users as a mailing list; and

adding the identified one or more other users to a group of mailing lists;

identifying email messages sent corresponding to the detected indication of automation;

performing an action in response to the identified email messages, wherein the action comprises moving one or more of the identified email messages to a specified email folder, marking as read one or more of the identified email messages, deleting one or more of the identified email messages, and filtering out one or more of the identified email messages;

determining whether the one or more other users in the group of mailing lists has sent email messages to the user;

based on determining that the one or more other users in the group of mailing lists has sent email messages to the user, removing the one or more other users from the group of mailing lists; and

displaying to the user a listing of emails received from the sender and providing a visual indication for the identified email messages on listing of emails, wherein the visual indication for identified email messages is different from a visual indication for unidentified email messages.
