Postbye Subscription Cancellation Guides

Postbye (https://postbye.com/) cancels subscriptions for you by mailing a formal cancellation letter, tracked until it is delivered.

This free Actor looks up a company in Postbye's public cancellation-guide database and returns, as structured data, how that company takes cancellations (mail, in person, online, email), the notice period, the traps to check first, the mailing address on file, the guide URL on postbye.com and, if you ask for it, a ready-to-fill plain-text cancellation letter. It needs no API key and no account on any other service.

What you get

For each matching company one dataset item with:

How to use

1. Open the Actor and type a company name (for example Planet Fitness) or a Postbye slug (planet-fitness).
2. Optionally raise maxResults (1 to 10) to get the closest matches, or switch on includeLetter to add the letter text. Add your name and account number to fill those placeholders in the letter.
3. Click Start and read the dataset (JSON, CSV, Excel or the API).

Input example

{
  "company": "Planet Fitness",
  "maxResults": 1,
  "includeLetter": true
}

Output example

  "category": "Gyms & fitness",
  "method": "letter",
  "howToCancel": "Mail (written notice to your home club), in person at your home club, or online (sign in to the member portal on planetfitness.com)",
  "noticePeriod": "Cancel at least 7 days before the next billing date; same 7 days before the annual fee date",

}

How it works

The Actor calls Postbye's public, read-only MCP endpoint https://postbye.com/mcp (JSON-RPC over HTTP POST, Streamable HTTP) with the tools search_companies, get_cancellation_guide and, if requested, get_cancellation_letter. Nothing you enter is stored by the Actor. If no guide matches, the dataset stays empty and the run log says so.

You can use the same endpoint directly from an MCP client such as Claude, Cursor or ChatGPT. Setup instructions: https://postbye.com/mcp-server
