How to cancel Unnax by mail
Collect the details you need
You will need the account email, the last four digits of the linked bank account or card and the membership tier. Use exactly the details Unnax holds, so the request can be matched to your account.
Write the cancellation request
Unnax 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 the letter by certified mail
Send the letter to the L'Hospitalet de Llobregat mailing address shown below by certified mail. Keep the tracking number safe.
Hold on to the receipt
File the receipt with the letter. A Unnax charge dated after delivery is the one to dispute, and these two documents are what you quote.
With Postbye, steps 2 to 4 take about two minutes of your time.
Where your Unnax cancellation letter goes
Unnax takes its post at Plaça d'Europa 22, Planta 4, 08908 L'Hospitalet de Llobregat, Spain, which is where a cancellation letter belongs.
The postcode 08908 belongs to Barcelona, Spain, so this is where the envelope is delivered.
The letter greets the reader with “A quien corresponda,”; your own details sit under the labels Titular de la cuenta, Dirección de facturación registrada and Correo electrónico registrado.

Before you cancel Unnax, check these

- Check your bank statement after the cancellation date for any further charge.

Cancelling a finance or credit subscription
Finance and credit apps bill a membership fee through a linked account, so the request has to end the membership and the authorisation to take payments.
If a charge shows up after you cancelled, the letter and its receipt are what you put in front of the company or your bank.
