How to cancel Kertel by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Kertel can only act on a request it can match to an account.
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.
Mail it with tracking
Address the envelope to Kertel, Paris, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
File the delivery record
Once the letter is delivered, the date on the receipt is the date Kertel 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 Kertel cancellation letter goes
Kertel can be reached by post at Avenue des Champs-Élysées 6, immeuble d1, 75008 Paris, France.
The envelope is going to Paris in Île-de-France, France, so the postcode 75008 must be on the front.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Kertel, 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
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.
