Outlook.com offers the ability to add rules to your inbound traffic to help filter your mail. If you are part of a mailing list that gets a lot of emails, you may want to take advantage of these rules. Adding a rule to put these emails into a separate folder will help reduce “clutter” from your inbox folder. To accomplish this go to the settings of outlook.com and click Manage rules
From there click the New button, that will bring up the create rule page. Create a new rule when the email is sent to the mailing list.
Select a new folder for the mail to go into.
Click Save and from then on any mail to the mailing list will go to that folder!
