How to cancel Adeslas by mail
Collect the details you need
Adeslas 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
Adeslas 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.
Send it by certified mail
Send the letter to the Madrid mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
It shows the date Adeslas received your letter. Check your next statement: no Adeslas charge should post after the cancellation date.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Adeslas cancellation letter goes
Adeslas can be reached by post at Paseo de la Castellana 259, C, 28046 Madrid, Spain.
The envelope is going to Madrid, Spain, so the postcode 28046 must be on the front.
Your name, address and email appear in a short block labelled Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado, under the greeting “A quien corresponda,”.

Before you cancel Adeslas, check these
- 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.
- If an app store or phone carrier bills you, the company cannot cancel it. Cancel with that partner as well.
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.
