How to cancel Smart Fit by mail
Get your account details together
Have your membership number, the home club you joined at and the name on the membership agreement to hand. The details in the letter need to match what Smart Fit has on file.
Draft the request
Postbye drafts the request in Brazilian Portuguese, the language of Brazil, with “Assunto: Solicitação de cancelamento – [your name]” as the subject line. It asks Smart Fit to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Use certified mail for the 01310100 São Paulo address in the next section, so the post office records the delivery. Write down the tracking number.
File the delivery record
File the receipt with the letter. A Smart Fit charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Smart Fit cancellation letter goes
The mailing address we hold for Smart Fit is Avenida Paulista 1294, 01310100 São Paulo, Brazil.

Before you cancel Smart Fit, 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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
