If you are a Gmail user, you probably know that you can quickly create an email alias by appending random term with a “+” behind your username. For example, if your username is firstname.lastname@example.org, you can use random alias like email@example.com and it will still be sent to firstname.lastname@example.org. The good news is that for Outlook.com users, you can use this “+” aliasing method as well.
So if your email address is email@example.com, any email alias of the format “firstname.lastname@example.org” will still reach your inbox. You can then make use of Rules (Sweep -> Manage Rules) to setup filter for your incoming email. (it will work for Hotmail.com as well)
