How to cancel Aggerenergie by mail
Start with your account details
Aggerenergie 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.
Draft the request
Aggerenergie 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.
Post the letter
Mail the letter by certified mail to the Gummersbach address in the next section, and keep the tracking number.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Aggerenergie charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Aggerenergie cancellation letter goes
Aggerenergie can be reached by post at Alexander-Fleming-Straße 2, 51643 Gummersbach, Germany.
The postcode 51643 belongs to Nordrhein-Westfalen, Germany, so this is where the envelope is delivered.

Before you cancel Aggerenergie, 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
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.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
