How to cancel Pro Natura by mail
Find your account details
Start with your donor or supporter number, the name on the donation and the amount and date of the latest payment, so the request to Pro Natura names the right account the first time.
Write your request
The request is prepared in German (template de), under the subject line “Betreff: Kündigungsanfrage – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Mail the letter with a receipt
Address the envelope to Pro Natura, Basel, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Delivery confirmation is your evidence that Pro Natura was asked. Watch the next statement or two for any further Pro Natura charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Pro Natura cancellation letter goes
Pro Natura can be reached by post at Postfach, kundenservice, 4018 Basel, Switzerland.
“Postfach” 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 “Sehr geehrte Damen und Herren,”; your own details sit under the labels Kontoinhaber, Hinterlegte Rechnungsadresse and Hinterlegte E-Mail-Adresse.

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.
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.
