How to cancel Must Energia by mail
Find your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Must Energia is the easiest one to set aside.
Prepare the letter
Must Energia 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.
Mail it with tracking
Address the envelope to Must Energia, Milano, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Must Energia 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.

Before you cancel Must Energia, check these
- 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.
- Check your next statement: no charge should appear after the cancellation date.
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
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
