How to cancel Yonivers by mail
Find your account details
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Yonivers is only as good as the details it quotes.
Set out the request
Postbye writes the letter in French from our French template, because Yonivers's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Yonivers to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Send the letter to the Paris mailing address shown below by certified mail. Keep the tracking number safe.
Keep the delivery receipt
The receipt dates your request. Look at your next statement for any Yonivers charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Yonivers cancellation letter goes
For a letter to Yonivers, use Rue Saint-Victor 5, 75005 Paris, France.
Copy the postal code 75005 exactly: it is what routes the letter to Île-de-France, France.
Your details go in a block headed by Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, and the opening line is “À qui de droit,”.

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