How to cancel Estenergy by mail
Collect the details you need
Have the name and email on the account and, if you have one, an account or customer number to hand. The details in the letter need to match what Estenergy has on file.
Write the cancellation request
Postbye drafts the request in Italian, the language of Italy, with “Oggetto: Richiesta di cancellazione – [your name]” as the subject line. It asks Estenergy to close the subscription, stop billing and confirm in writing.
Send the letter by certified mail
Send it certified to Trieste, Italy, copying the address from the next section letter for letter, and keep the receipt slip.
Keep proof the letter arrived
Delivery confirmation is your evidence that Estenergy was asked. Watch the next statement or two for any further Estenergy charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Estenergy, check these
- 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.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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 phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
