How to cancel Oenergy by mail
Note 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 Oenergy holds, so the request can be matched to your account.
Draft the request
The request is prepared in Italian (template it), under the subject line “Oggetto: Richiesta di cancellazione – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post the letter
Use certified mail for the 20124 Milano address in the next section, so the post office records the delivery. Write down the tracking number.
Hold on to the receipt
Delivery confirmation is your evidence that Oenergy was asked. Watch the next statement or two for any further Oenergy charge.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Oenergy cancellation letter goes
Written requests to Oenergy go to Via Fabio Filzi 27, 20124 Milano, Italy.
The envelope is going to Milano in Lombardia, Italy, so the postcode 20124 must be on the front.
The letter greets the reader with “A chi di competenza,”; your own details sit under the labels Titolare dell'account, Indirizzo di fatturazione registrato and Email registrata.

Before you cancel Oenergy, check these
- 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.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
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.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
