How to cancel Deka by mail
Collect the details you need
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Deka is only as good as the details it quotes.
Write your request
Deka 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 it with proof of delivery
Take the letter to the post office and ask for certified delivery to 60325 Frankfurt am Main. Keep the tracking number it gives you.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Deka charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Deka cancellation letter goes
Deka can be reached by post at Mainzer Landstraße 16, 60325 Frankfurt am Main, Germany.
Postal code 60325 places the address in Hessen, Germany.

Before you cancel Deka, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
