How to cancel Cdu by mail

  1. Find your account details

    Cdu 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.

  2. Put the request in writing

    Postbye writes the letter in German from our German template, because Cdu's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Cdu to end the subscription, stop all further charges and confirm in writing.

  3. Post it with proof of delivery

    Use certified mail for the 10785 Berlin address in the next section, so the post office records the delivery. Write down the tracking number.

  4. Hold on to the receipt

    File the receipt with the letter. A Cdu 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 Cdu, 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.

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.

If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.

Cdu cancellation questions

Where do I send my Cdu cancellation letter?

Address the letter to Cdu, Klingelhöferstraße 8, 10785 Berlin, Germany.

Which language is my Cdu letter written in?

German. Cdu's address is in Germany, so the letter is prepared from the German template under the subject line “Betreff: Kündigungsanfrage – [your name]”.

What do I need to cancel Cdu?

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 Cdu has on file.

Will Cdu confirm my cancellation?
