How to cancel Smatis by mail
Gather 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 Smatis names the right account the first time.
Prepare the letter
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Smatis to close the subscription, stop billing and confirm in writing.
Post it with proof of delivery
Use certified mail for the 16006 Angoulême address in the next section, so the post office records the delivery. Write down the tracking number.
Save the tracking record
Keep the tracking record with your copy of the letter. If Smatis 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.

Before you cancel Smatis, 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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
