How to cancel Croire by mail
Note your account details
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Croire has on file.
Prepare the letter
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Croire to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Send the letter to the Lille mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
Delivery confirmation is your evidence that Croire was asked. Watch the next statement or two for any further Croire charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Croire, check these
- 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.
- Use the same name and email as on the account. A mismatch can delay the request.
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.
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.
