How to cancel Banco Santander by mail
Gather 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 Banco Santander holds, so the request can be matched to your account.
Draft the request
Because Banco Santander is dealt with in Spanish, the letter is written in Spanish (template es). Subject: “Asunto: Solicitud de cancelación – [your name]”. It requests an end to the subscription and to every further charge, plus written confirmation.
Post the letter
Take the letter to the post office and ask for certified delivery to 28027 Madrid. Keep the tracking number it gives you.
Keep the proof of delivery
Delivery confirmation is your evidence that Banco Santander was asked. Watch the next statement or two for any further Banco Santander charge.
With Postbye, steps 2 to 4 take about two minutes of your time.

Before you cancel Banco Santander, check these
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.

How cancelling by mail works
Subscriptions renew automatically, and a written request is the clearest record that you asked to stop it before the next billing date.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
