How to cancel Courlux by mail
Get your account details together
Put the name and email on the account and, if you have one, an account or customer number in front of you before you write: the request to Courlux is only as good as the details it quotes.
Write the cancellation request
Postbye writes the letter in French from our French template, because Courlux's address is in Belgium. It opens with the subject line “Objet : Demande d'annulation – [your name]” and asks Courlux to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Send it certified to Essen, Belgium, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
The receipt dates your request. Look at your next statement for any Courlux charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Courlux cancellation letter goes
For a letter to Courlux, use Postbus 10150, Courlux Klantendienst Hageman, 2910 Essen, Belgium.
“Postbus 10150” 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 database also lists Route de la Broye 117, 1623 Semsales, Switzerland for Courlux. Use the first address above unless your agreement names this one.
The letter greets the reader with “À qui de droit,”; your own details sit under the labels Titulaire du compte, Adresse de facturation enregistrée and E-mail enregistré.

Before you cancel Courlux, 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.

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.
