How to cancel Alter Mutua by mail
Find your account details
Before writing, collect the policy number, the name on the policy and the date you want cover to end. Alter Mutua can only act on a request it can match to an account.
Write your request
Alter Mutua 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.
Post the letter
Send it certified to Barcelona, Spain, copying the address from the next section letter for letter, and keep the receipt slip.
File the delivery record
Keep the tracking record with your copy of the letter. If Alter Mutua bills you after the date it received the request, you have the dates to point to.
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.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
