How to cancel Bnn by mail
Collect the details you need
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Bnn names the right account the first time.
Prepare the letter
Postbye writes the letter in German from our German template, because Bnn's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Bnn to end the subscription, stop all further charges and confirm in writing.
Post the letter
Mail the letter by certified mail to the Karlsruhe address in the next section, and keep the tracking number.
Keep the proof of delivery
It shows the date Bnn received your letter. Check your next statement: no Bnn charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Bnn, 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.
