How to cancel Gustav Gym by mail
Gather your account details
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 Gustav Gym is only as good as the details it quotes.
Put the request in writing
Postbye writes the letter in Dutch from our Dutch template, because Gustav Gym's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Gustav Gym to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send it certified to Amsterdam, Netherlands, copying the address from the next section letter for letter, and keep the receipt slip.
Hold on to the receipt
It shows the date Gustav Gym received your letter. Check your next statement: no Gustav Gym charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Gustav Gym cancellation letter goes
Gustav Gym lists George Gershwinlaan 520, tav Gym, 1082 MT Amsterdam, Netherlands as its mailing address.
The envelope is going to Amsterdam in Noord-Holland, Netherlands, so the postcode 1082 MT must be on the front.
The letter is addressed “Geachte heer/mevrouw,” and its details block uses the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel Gustav Gym, check these
- Annual fees and monthly dues are sometimes billed separately. Ask for both to be ended.
- 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.
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.
