How to cancel Promovendum by mail
Find your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Promovendum names the right account the first time.
Write your request
Postbye writes the letter in Dutch from our Dutch template, because Promovendum's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Promovendum to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Address the envelope to Promovendum, Dordrecht, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Save the tracking record
Keep the tracking record with your copy of the letter. If Promovendum 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 Promovendum cancellation letter goes
Written requests to Promovendum go to Postbus 362, 3300 AJ Dordrecht, Netherlands.
“Postbus 362” 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.

Before you cancel Promovendum, check these
- Use the same name and email as on the account. A mismatch can delay the request.
- 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.
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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
