How to cancel Cmi France by mail
Find your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Cmi France can only act on a request it can match to an account.
Draft the request
Cmi France 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.
Send the letter by certified mail
Send the letter to the Chantilly mailing address shown below by certified mail. Keep the tracking number safe.
Save the tracking record
Once the letter is delivered, the date on the receipt is the date Cmi France 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 Cmi France cancellation letter goes
Cmi France lists Avenue du Général Leclerc 45, 60500 Chantilly, France as its mailing address.
Copy the postal code 60500 exactly: it is what routes the letter to Hauts-de-France, France.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Cmi France, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.

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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
