How to cancel Alterna by mail
Collect the details you need
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Alterna is only as good as the details it quotes.
Prepare the letter
Because Alterna is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send the letter by certified mail
Send the letter to the Paris mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
Delivery confirmation is your evidence that Alterna was asked. Watch the next statement or two for any further Alterna charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Alterna cancellation letter goes
Alterna can be reached by post at Boulevard Haussmann 75, 75008 Paris, France.
The envelope is going to Paris in Île-de-France, France, so the postcode 75008 must be on the front.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Alterna, 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.
A letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
