How to cancel Knvvl by mail
Note your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Knvvl is the easiest one to set aside.
Draft the request
Because Knvvl is dealt with in Dutch, the letter is written in Dutch (template nl). Subject: “Onderwerp: annuleringsverzoek – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Mail it with tracking
Address the envelope to Knvvl, Woerden, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the proof of delivery
It shows the date Knvvl received your letter. Check your next statement: no Knvvl charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Knvvl cancellation letter goes
For a letter to Knvvl, use Houttuinlaan 16-A, 3447 GM Woerden, Netherlands.
The postcode 3447 GM belongs to Utrecht, Netherlands, so this is where the envelope is delivered.
Your details go in a block headed by Accounthouder, Factuuradres in dossier and E-mailadres in dossier, and the opening line is “Geachte heer/mevrouw,”.

Before you cancel Knvvl, check these
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
