How to cancel Fitnext by mail
Collect the details you need
Put your membership number, the home club you joined at and the name on the membership agreement in front of you before you write: the request to Fitnext is only as good as the details it quotes.
Write the cancellation request
Postbye drafts the request in French, the language of France, with “Objet : Demande d'annulation – [your name]” as the subject line. It asks Fitnext to close the subscription, stop billing and confirm in writing.
Mail it with tracking
Mail the letter by certified mail to the Paris address in the next section, and keep the tracking number.
Keep the proof of delivery
It shows the date Fitnext received your letter. Check your next statement: no Fitnext charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Fitnext cancellation letter goes
Fitnext takes its post at Rue de Saussure 8, 75017 Paris, France, which is where a cancellation letter belongs.
Postal code 75017 places the address in 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 Fitnext, check these
- A home club can have its own rules. Name the club in the letter so the request is not bounced between locations.
- Freezing or pausing a membership is not cancelling it. Say clearly that you want the membership ended.
- Read the notice window in your agreement. A letter that arrives after the cut-off can miss that month's charge.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

Cancelling a gym or fitness membership
Gyms often require written notice, set a notice window before the next billing date and can tie the cancellation to the home club, so a dated letter is the record that counts.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
