How to cancel Closer by mail
Collect the details you need
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Closer names the right account the first time.
Prepare the letter
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
Send it certified to Lille, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Closer 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 Closer cancellation letter goes

Before you cancel Closer, 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.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
