How to cancel Donau by mail
Get your account details together
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 Donau is the easiest one to set aside.
Draft 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 Wien address in the next section, and keep the tracking number.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Donau 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.

Before you cancel Donau, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.
