Postbye vs Unsubby

Unsubby is a cancellation service that sends a termination letter for you. Its FAQ says the letter is “dispatched” and “forwarded” but not whether that is by paper mail or by email, and it never mentions certified or registered delivery. Postbye mails a printed letter by certified mail with return receipt, for any company with a mailing address, and sends you the delivery proof. Unsubby lists two prices, one per cancellation and one for a four-week plan, so check which one applies to you.
