Mail Shepherd Help.
Mail Shepherd 3.0 (build 454) · Updated October 21, 2026
Mail Shepherd’s goal is to keep unwanted mail completely out of your mailbox by helping you quickly identify, block and delete it.
Everything runs on your Mac, inside Apple Mail. There’s no Mail Shepherd server or account, and you never hand your email password or mailbox access to another company’s service. Your mail, your lists and the logs stay on this Mac.
