How to cancel E Flux by mail
Collect the details you need
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 E Flux is only as good as the details it quotes.
Set out the request
Postbye writes the letter in Dutch from our Dutch template, because E Flux's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks E Flux to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Mail the letter by certified mail to the Duivendrecht address in the next section, and keep the tracking number.
Keep the delivery receipt
File the receipt with the letter. A E Flux charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your E Flux cancellation letter goes
E Flux takes its post at Joan Muyskenweg 37, 1115 RC Duivendrecht, Netherlands, which is where a cancellation letter belongs.
The envelope is going to Duivendrecht in Noord-Holland, Netherlands, so the postcode 1115 RC must be on the front.
The letter is addressed “Geachte heer/mevrouw,” and its details block uses the labels Accounthouder, Factuuradres in dossier and E-mailadres in dossier.

Before you cancel E Flux, check these
- 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.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
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
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
