How to cancel Santander Seguros by mail
Collect the details you need
Before writing, collect the policy number, the name on the policy and the date you want cover to end. Santander Seguros can only act on a request it can match to an account.
Prepare the letter
Santander Seguros 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.
Mail the letter with a receipt
Use certified mail for the 28660 Madrid address in the next section, so the post office records the delivery. Write down the tracking number.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Santander Seguros was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

Cancelling a insurance or protection plan
Insurers cancel by policy and by effective date, so the request has to name the policy number and the date cover should stop, ideally after replacement cover is in place.
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.
