@Machinegun Welcome to the forum!  As @deanishe suggest, a File Filter workflow is ideal for searching specific types/locations like emails.   If you'd like to search Mail.app by sender, you can use this workflow (which also allows you to search by subject line or content), where pressing Return on a result will launch the specific email you've selected: https://www.dropbox.com/s/5h3djhw2thf8xjp/Mail.app Search 3.0.alfredworkflow?dl=0   Cheers, Vero
