How to cancel Avenir Mutuelle by mail
Note 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 Avenir Mutuelle is the easiest one to set aside.
Draft the request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Avenir Mutuelle to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Address the envelope to Avenir Mutuelle, Paris, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Avenir Mutuelle 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.
Where your Avenir Mutuelle cancellation letter goes
Avenir Mutuelle takes its post at Rue de Bercy 173, 75012 Paris, France, which is where a cancellation letter belongs.
The envelope is going to Paris in Île-de-France, France, so the postcode 75012 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 Avenir Mutuelle, 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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
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.
