How to cancel Naturgy by mail
Start with 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 Naturgy is the easiest one to set aside.
Put the request in writing
Naturgy is based in Spain, so the letter goes out in Spanish, built from our Spanish template. Subject line: “Asunto: Solicitud de cancelación – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Post the letter
Send it certified to Madrid, Spain, copying the address from the next section letter for letter, and keep the receipt slip.
Keep the delivery receipt
Keep the tracking record with your copy of the letter. If Naturgy 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.

Every address we hold for Naturgy, with the envelope wording
Before you cancel Naturgy, check these
- 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.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
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.
