How to cancel Atmb by mail
Find your account details
Atmb 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.
Write the cancellation 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 the letter by certified mail
Send it certified to Nangy, France, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Atmb 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.

Before you cancel Atmb, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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.
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.
