How to cancel Superfit by mail
Note your account details
Check your membership number, the home club you joined at and the name on the membership agreement before anything else. A request that does not match the account on file at Superfit is the easiest one to set aside.
Set out the request
Postbye writes the letter in German from our German template, because Superfit's address is in Austria. It opens with the subject line “Betreff: Kündigungsanfrage – [your name]” and asks Superfit to end the subscription, stop all further charges and confirm in writing.
Post it with proof of delivery
Send it certified to Feldkirchen bei Graz, Austria, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Superfit charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Superfit cancellation letter goes
For a letter to Superfit, use Legero-United-Straße 4, 8073 Feldkirchen bei Graz, Austria.
The envelope is going to Feldkirchen bei Graz in Steiermark, Austria, so the postcode 8073 must be on the front.
Your details go in a block headed by Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse, and the opening line is “Sehr geehrte Damen und Herren,”.

Before you cancel Superfit, check these
- 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.
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
