How to cancel Jonnym by mail
Get your account details together
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 Jonnym has on file.
Put the request in writing
Because Jonnym is dealt with in German, the letter is written in German (template de). Subject: “Betreff: Kündigungsanfrage – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail the letter with a receipt
Address the envelope to Jonnym, Bietigheim-Bissingen, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the delivery receipt
File the receipt with the letter. A Jonnym 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 Jonnym, 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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
