How to cancel Curves by mail
Gather your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Curves can only act on a request it can match to an account.
Write your request
Curves is based in Spain, so the letter goes out in Spanish, built from our Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Post it by certified mail to Curves in Alboraya, Spain, using the exact address below, and note the tracking number.
Hold on to the receipt
Delivery confirmation is your evidence that Curves was asked. Watch the next statement or two for any further Curves charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Curves, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- 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.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
