Connects Muse to SendRegistered so you can prepare and mail registered letters with proof of delivery, nationally and internationally. Muse can help draft the letter, set up the mailing and check delivery status.

Example request: "Send this cancellation letter to my landlord by registered mail and tell me when it is delivered."

How to connect: SendRegistered is not in Muse's Connectors list yet, and it needs you to sign in with your SendRegistered account. Apps that need this kind of sign-in usually cannot be used from a Muse chat yet. Follow it here and we will tell you when it reaches Muse.
