How to cancel KMU-Krankenversicherung by mail
Get your account details together
Before writing, collect the name and email on the account and, if you have one, an account or customer number. KMU-Krankenversicherung can only act on a request it can match to an account.
Prepare the letter
Because KMU-Krankenversicherung 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.
Send it by certified mail
Send it certified to Winterthur, Switzerland, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
The receipt dates your request. Look at your next statement for any KMU-Krankenversicherung charge after that date.

Before you cancel KMU-Krankenversicherung, 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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
