How to cancel Cavalassur by mail
Collect the details you need
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Cavalassur names the right account the first time.
Write your request
Cavalassur 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.
Post it with proof of delivery
Take the letter to the post office and ask for certified delivery to 60500 Chantilly. Keep the tracking number it gives you.
Keep the delivery receipt
File the receipt with the letter. A Cavalassur charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Cavalassur cancellation letter goes
Cavalassur can be reached by post at Avenue du Général de Gaulle 1, 60500 Chantilly, France.
The envelope is going to Chantilly in Hauts-de-France, France, so the postcode 60500 must be on the front.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Cavalassur, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- 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.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
