The sorting lives in your mailbox, not in an app.
On Gmail, each category is an ordinary label — Sortmail/Receipts, Sortmail/Newsletters — and filed mail leaves the inbox. On Outlook, it is a category of the same name, and filed mail moves to Archive. They show up in every mail app you use, and they stay if you stop using Sortmail.
With unsubscribe tools: Unsubscribing stops the mail for good, and Clean Email moves mail from lists you unsubscribe from or pause to the trash.[3]
