How to cancel Adformatie by mail
Collect the details you need
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 Adformatie is the easiest one to set aside.
Write your request
Adformatie is based in Netherlands, so the letter goes out in Dutch, built from our Dutch template. Subject line: “Onderwerp: annuleringsverzoek – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post it with proof of delivery
Send the letter to the Amsterdam mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
It shows the date Adformatie received your letter. Check your next statement: no Adformatie charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Adformatie, check these
- Check your next statement: no charge should appear after the cancellation date.
- 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.

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.
