How to cancel Waddenvereniging by mail
Collect the details you need
Put your donor or supporter number, the name on the donation and the amount and date of the latest payment in front of you before you write: the request to Waddenvereniging is only as good as the details it quotes.
Set out the request
Waddenvereniging 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.
Mail it with tracking
Take the letter to the post office and ask for certified delivery to 8860 AB Harlingen. Keep the tracking number it gives you.
Save the tracking record
Keep the tracking record with your copy of the letter. If Waddenvereniging bills you after the date it received the request, you have the dates to point to.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Waddenvereniging cancellation letter goes
For a letter to Waddenvereniging, use Postbus 90, 8860 AB Harlingen, Netherlands.
“Postbus 90” 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 greets the reader with “Geachte heer/mevrouw,”; your own details sit under 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.
