How to cancel Youstar by mail
Get your account details together
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Youstar holds, so the request can be matched to your account.
Put the request in writing
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
Use certified mail for the 75011 Paris address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
Delivery confirmation is your evidence that Youstar was asked. Watch the next statement or two for any further Youstar charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Youstar cancellation letter goes
For a letter to Youstar, use Rue de la Fontaine au Roi 16, 75011 Paris, France.
The envelope is going to Paris in Île-de-France, France, so the postcode 75011 must be on the front.
Inside, the salutation reads “À qui de droit,”, followed by your details under Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

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