Postbye - 2026 Pricing, Features, Reviews & Alternatives

Postbye cancels subscriptions for you by mailing a formal cancellation letter by certified mail, tracked until it is delivered. Tell Postbye which company you want to leave, and it writes the letter, mails it the next business day, tracks it and shows the proof of delivery, so the cancellation is documented in writing.

Search 8,674 cancellation guides for subscriptions, memberships and gym contracts, including Netflix, Hulu, Amazon Prime, Planet Fitness, LA Fitness, SiriusXM, Spotify, Adobe, Audible, LinkedIn Premium and thousands more. For every company, the guide shows how it takes cancellations (letter, email or both), the notice period, the traps to check before you cancel, billing-partner notes, the mailing address on file and a ready-to-send cancellation letter.

Use Postbye to:

- cancel a subscription or membership by mail

- cancel a gym membership with a certified mail letter

- stop recurring charges and unwanted subscription billing

- cancel streaming, insurance, telecom, software and magazine plans

- keep proof of delivery in case a charge appears after you cancelled

- find a company's cancellation address and notice period

- write a cancellation letter from a free template, ready to copy, print or save as a PDF

Postbye is built for individual consumers in the United States who want to cancel auto-renewing subscriptions without waiting on hold or fighting a cancellation maze, and for personal finance and subscription management workflows. The guides and the letter template are free to use.

For AI assistants and developers, Postbye also provides a free, read-only MCP server and cancellation API for Claude, ChatGPT, Cursor, VS Code and any AI agent. It needs no API key and exposes four tools: search_companies, get_cancellation_guide, get_cancellation_letter and list_categories.
