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 Caixa Enginyers holds, so the request can be matched to your account.
Put the request in writing
The request is prepared in Spanish (template es), under the subject line “Asunto: Solicitud de cancelación – [your name]”: end the subscription, stop all further charges and confirm in writing to you.
Send the letter by certified mail
Use certified mail for the 08007 Barcelona address in the next section, so the post office records the delivery. Write down the tracking number.
Keep the proof of delivery
Keep the tracking record with your copy of the letter. If Caixa Enginyers bills you after the date it received the request, you have the dates to point to.

Before you cancel Caixa Enginyers, check these
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
- Cancelling usually ends access at the end of the period you paid for, so you keep what you paid for until then.
- Use the same name and email as on the account. A mismatch can delay the request.
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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
