How to cancel Cosmopolitan by mail
Note your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Cosmopolitan can only act on a request it can match to an account.
Prepare the letter
Cosmopolitan 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.
Mail the letter with a receipt
Mail the letter by certified mail to the Hamburg address in the next section, and keep the tracking number.
File the delivery record
Keep the tracking record with your copy of the letter. If Cosmopolitan bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cosmopolitan cancellation letter goes
The mailing address we hold for Cosmopolitan is Meßberg 1, 20095 Hamburg, Germany.
The envelope is going to Hamburg, Germany, so the postcode 20095 must be on the front.
The database also lists West 57th Street 300, New York 10019 for Cosmopolitan. Use the first address above unless your agreement names this one.
The letter is addressed “Sehr geehrte Damen und Herren,” and its details block uses the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

Before you cancel Cosmopolitan, 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.
