How to cancel Interplanet by mail
Find your account details
You will need the name and email on the account and, if you have one, an account or customer number. Use exactly the details Interplanet holds, so the request can be matched to your account.
Write your request
Interplanet is based in Italy, so the letter goes out in Italian, built from our Italian template. Subject line: “Oggetto: Richiesta di cancellazione – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Use certified mail for the 20146 Milano address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
The receipt dates your request. Look at your next statement for any Interplanet charge after that date.
With Postbye, steps 2 to 4 take about two minutes of your time.

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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
