How to cancel Milieudefensie by mail
Get your account details together
Check your donor or supporter number, the name on the donation and the amount and date of the latest payment before anything else. A request that does not match the account on file at Milieudefensie is the easiest one to set aside.
Put the request in writing
Milieudefensie 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 the letter
Send it certified to Amsterdam, Netherlands, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
It shows the date Milieudefensie received your letter. Check your next statement: no Milieudefensie charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Milieudefensie cancellation letter goes
Milieudefensie takes its post at Postbus 19199, 1000 GD Amsterdam, Netherlands, which is where a cancellation letter belongs.
“Postbus 19199” 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.
The letter is addressed “Geachte heer/mevrouw,” and its details block uses the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Cancelling a regular donation
Regular donations run until the donor ends them, so a written request should give the donor reference and ask the charity to stop the payment and confirm the end date.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
