How to cancel Bonus Strom by mail
Start with your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Bonus Strom is the easiest one to set aside.
Set out the request
The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Mail the letter by certified mail to the Fahrdorf address in the next section, and keep the tracking number.
Save the tracking record
File the receipt with the letter. A Bonus Strom charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Bonus Strom, check these
- Check your next statement: no charge should appear after the cancellation date.

How cancelling by mail works
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
