How to cancel Boxx by mail

  1. Get your account details together

    You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Boxx holds, so the request can be matched to your account.

  2. Write your request

    Postbye writes the letter in Dutch from our Dutch template, because Boxx's address is in Netherlands. It opens with the subject line “Onderwerp: annuleringsverzoek – [your name]” and asks Boxx to end the subscription, stop all further charges and confirm in writing.

  3. Mail the letter with a receipt

    Take the letter to the post office and ask for certified delivery to 1014 AS Amsterdam. Keep the tracking number it gives you.

  4. Keep the delivery receipt

    The receipt dates your request. Look at your next statement for any Boxx charge after that date.

With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Boxx, check these

  • If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
  • Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
  • Use the same name and email as on the account. A mismatch can delay the request.

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.
