How to cancel Adventiss by mail
Start with your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Adventiss names the right account the first time.
Write your request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Adventiss to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Mail the letter by certified mail to the Goustranville address in the next section, and keep the tracking number.
Keep the proof of delivery
The receipt dates your request. Look at your next statement for any Adventiss charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Adventiss, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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.
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.
