How to cancel Winnie by mail
Start with 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 Winnie has on file.
Prepare the letter
Because Winnie is dealt with in French, the letter is written in French (template fr). Subject: “Objet : Demande d'annulation – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 60500 Chantilly. Keep the tracking number it gives you.
Keep proof the letter arrived
Keep the tracking record with your copy of the letter. If Winnie bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Winnie cancellation letter goes
For a letter to Winnie, use Avenue du Général Leclerc 45, 60500 Chantilly, France.

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