How to cancel Horizons by mail

  1. Find your account details

    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 Horizons is the easiest one to set aside.

  2. Put the request in writing

    Horizons is based in France, so the letter goes out in French, built from our French template. Subject line: “Objet : Demande d'annulation – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.

  3. Mail the letter with a receipt

    Use certified mail for the 75116 Paris address in the next section, so the post office records the delivery. Write down the tracking number.

  4. Keep proof the letter arrived

    Once the letter is delivered, the date on the receipt is the date Horizons was told. Compare it with your statements over the next billing cycle.

With Postbye, steps 2 to 4 take about two minutes of your time.

Every address we hold for Horizons, with the envelope wording

Before you cancel Horizons, 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.

Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
