How to cancel Mnfct 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 Mnfct 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 Mnfct to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 93100 Montreuil. Keep the tracking number it gives you.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Mnfct was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Mnfct cancellation letter goes
Mnfct can be reached by post at Rue Franklin 3, 93100 Montreuil, France.
The envelope is going to Montreuil in Île-de-France, France, so the postcode 93100 must be on the front.
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 Mnfct, 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
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.
