How to cancel Cwi Corporate by mail
Note your account details
Cwi Corporate will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Draft the request
The request is prepared in French (template fr), under the subject line “Objet : Demande d'annulation – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send it by certified mail
Post it by certified mail to Cwi Corporate in Aix-en-Provence, France, using the exact address below, and note the tracking number.
Hold on to the receipt
File the receipt with the letter. A Cwi Corporate 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.

Before you cancel Cwi Corporate, 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
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.
