How to cancel Eterna Aseguradora by mail
Start with your account details
Before writing, collect the name and email on the account and, if you have one, an account or customer number. Eterna Aseguradora can only act on a request it can match to an account.
Prepare the letter
The request is prepared in Spanish (template es), under the subject line “Asunto: Solicitud de cancelación – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Post the letter
Take the letter to the post office and ask for certified delivery to 28008 Madrid. Keep the tracking number it gives you.
Keep the delivery receipt
It shows the date Eterna Aseguradora received your letter. Check your next statement: no Eterna Aseguradora charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Eterna Aseguradora cancellation letter goes

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.
