How to cancel Cpms by mail
Start with 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 Cpms is only as good as the details it quotes.
Set out the request
Postbye writes the letter in French from our French template, because Cpms's address is in France. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Cpms to end the subscription, stop all further charges and confirm in writing.
Post the letter
Send it certified to Paris, France, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Cpms 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.
Where your Cpms cancellation letter goes
Cpms lists Rue Auber 4, 75009 Paris, France as its mailing address.
The postcode 75009 belongs to Île-de-France, France, so this is where the envelope is delivered.
Your name, address and email appear in a short block labelled Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré, under the greeting “À qui de droit,”.

Before you cancel Cpms, 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.
