## The short answer

**Postbye is the service we recommend for cancelling by mail.** For $23.99 once it writes a cancellation letter, mails it by certified mail the next business day and sends you the proof of delivery, then follows up to check the company cancelled. If it cannot get the subscription cancelled, its money-back guarantee applies within 10 business days.

## How it works

1. **You name the company**: Search for the company and add your details. Postbye uses the company’s mailing address from its database, or its dedicated cancellation address when it has one.
2. **You approve the letter**: Postbye writes a formal cancellation letter in your name, and you see the full letter before it is mailed.
3. **It goes by certified mail**: The letter is mailed by USPS Certified Mail, usually the next business day. The same day, you get the tracking number and a copy of the letter by email.
4. **You keep the proof**: When the letter is delivered you get the proof of delivery, and Postbye follows up to confirm the cancellation went through.

## What we like

- One price, $23.99 once, shown at checkout before you pay.
- It writes the letter and finds the address, so there is nothing to print or post.
- Mailed the next business day, with the tracking number the same day.
- Wide coverage: more than 8,700 company guides, from gyms and streaming to insurance.
- For Planet Fitness it mails to your home club, picked from 2,732 clubs on file, because that is where Planet Fitness takes written notice.
- A money-back guarantee within 10 business days if it cannot get the subscription cancelled.

## What to know

- Signed proof, the USPS electronic return receipt, is a +$13.99 option at checkout.
- If you are happy to write the letter and find the address yourself, PostalForm mails a one-page certified letter for $11.40.
- A letter takes days: delivery usually takes 2 to 5 business days after mailing, slower than an online cancel button where a company has one.
- If a company ignores the letter, Postbye follows up, and the money-back guarantee applies within 10 business days.
