How to cancel Hamburg Wasser by mail
Start with your account details
Hamburg Wasser 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
Hamburg Wasser is based in Germany, so the letter goes out in German, built from our German template. Subject line: “Betreff: Kündigungsanfrage – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Send it certified to Hamburg, Germany, copying the address from the next section letter for letter, and keep the receipt slip.
Save the tracking record
The receipt dates your request. Look at your next statement for any Hamburg Wasser charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Hamburg Wasser, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
Hamburg Wasser's own site is hamburgwasser.de. Check its account and billing area first to see whether the plan is billed by Hamburg Wasser itself or by a partner.
