How to cancel Kube by mail
Collect the details you need
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 Kube has on file.
Prepare the letter
Postbye writes the letter in French from our French template, because Kube's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Kube to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Take the letter to the post office and ask for certified delivery to 92120 Montrouge. Keep the tracking number it gives you.
File the delivery record
Keep the tracking record with your copy of the letter. If Kube 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 Kube cancellation letter goes
For a letter to Kube, use Rue Périer 20, 92120 Montrouge, France.
Montrouge is in Île-de-France, France; the postal code to quote is 92120.
The letter is addressed “À qui de droit,” and its details block uses the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

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