How to cancel Quest by mail
Note your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Quest holds, so the request can be matched to your account.
Write your request
Postbye writes the letter in Dutch from our Dutch template, because Quest's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Quest to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Mail the letter by certified mail to the Amsterdam address in the next section, and keep the tracking number.
Keep proof the letter arrived
It shows the date Quest received your letter. Check your next statement: no Quest charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Quest cancellation letter goes
Quest takes its post at Postbus 10985, 1001 EZ Amsterdam, Netherlands, which is where a cancellation letter belongs.
“Postbus 10985” is a post-office box or mail-sorting line, so it takes post and not couriers: certified mail is the right way to reach it.
Inside, the salutation reads “Geachte heer/mevrouw,”, followed by your details under Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel Quest, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
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.
