How to cancel Heise by mail
Start with your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Heise has on file.
Write the cancellation request
Postbye writes the letter in German from our German template, because Heise's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Heise to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Use certified mail for the 30625 Hannover address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Heise 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 Heise cancellation letter goes
Written requests to Heise go to Karl-Wiechert-Allee 10, 30625 Hannover, Germany.
Copy the postal code 30625 exactly: it is what routes the letter to Niedersachsen, Germany.
Your name, address and email appear in a short block labelled Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, under the greeting “Sehr geehrte Damen und Herren,”.

Before you cancel Heise, 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
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.
