How to cancel Horizont by mail
Get your account details together
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Horizont is the easiest one to set aside.
Write your request
Postbye writes the letter in German from our German template, because Horizont's address is in Germany. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Horizont to end the subscription, stop all further charges and confirm in writing.
Post the letter
Send the letter to the Frankfurt am Main mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
It shows the date Horizont received your letter. Check your next statement: no Horizont charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Horizont, check these
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- 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.
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.
