How to cancel B One by mail
Collect the details you need
B One will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Prepare the letter
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks B One to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Mail the letter by certified mail to the Einbeck address in the next section, and keep the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If B One bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel B One, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
