How to cancel Endesa by mail
Gather your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Endesa names the right account the first time.
Write the cancellation request
Postbye writes the letter in Spanish from our Spanish template, because Endesa's address is in Spain. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Endesa to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Mail the letter by certified mail to the Madrid address in the next section, and keep the tracking number.
Hold on to the receipt
It shows the date Endesa received your letter. Check your next statement: no Endesa charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Endesa, 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.

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.
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.
