How to cancel Alsa by mail
Find your account details
Alsa will look your account up from what the letter says, so check the name and email on the account and, if you have one, an account or customer number first.
Write your request
Postbye writes the letter in Spanish from our Spanish template, because Alsa's address is in Spain. It opens with the subject line “Asunto: Solicitud de cancelación – [your name]” and asks Alsa to end the subscription, stop all further charges and confirm in writing.
Mail the letter with a receipt
Post it by certified mail to Alsa in Madrid, Spain, using the exact address below, and note the tracking number.
Keep proof the letter arrived
Once the letter is delivered, the date on the receipt is the date Alsa 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.
Where your Alsa cancellation letter goes

Before you cancel Alsa, check these
- Check your next statement: no charge should appear after the cancellation date.
- Look for annual or multi-month plans. A plan paid in advance usually runs to the end of the period you paid for.
- Write well before the next billing date. A request that arrives after it can leave one more charge on your statement.
Several states set rules for subscriptions that renew on their own. See what yours requires in automatic renewal laws by state.

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 letter is the formal route: it states the request in writing, carries a date and, sent by certified mail, comes with proof of delivery.
