How to cancel Martierra Seguros by mail
Start with your account details
Have the policy number, the name on the policy and the date you want cover to end to hand. The details in the letter need to match what Martierra Seguros has on file.
Put the request in writing
Postbye writes the letter in Spanish from our Spanish template, because Martierra Seguros's address is in Spain. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Martierra Seguros to end the subscription, stop all further charges and confirm in writing.
Send it by certified mail
Mail the letter by certified mail to the Madrid address in the next section, and keep the tracking number.
File the delivery record
Delivery confirmation is your evidence that Martierra Seguros was asked. Watch the next statement or two for any further Martierra Seguros charge.
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.
Putting the request in writing means there is a date on file for when you asked, which matters if a charge appears afterwards.
