How to cancel Bank11 by mail
Note your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Bank11 is only as good as the details it quotes.
Write your request
Postbye drafts the request in German, the language of Germany, with “Betreff: Kündigungsanfrage – [your name]” as the subject line. It asks Bank11 to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Send it certified to Neuss, Germany, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Bank11 was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Bank11 cancellation letter goes
For a letter to Bank11, use Postfach 100606, 41406 Neuss, Germany.
“Postfach 100606” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Your details go in a block headed by Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, and the opening line is “Sehr geehrte Damen und Herren,”.

Before you cancel Bank11, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
