How to cancel Jumpseller by mail
Find your account details
Start with the account email, the plan or product name and the invoice or order number from your latest receipt, so the request to Jumpseller names the right account the first time.
Draft the request
Postbye writes the letter in Portuguese from our Portuguese template, because Jumpseller's address is in Portugal. It opens with the subject line “Assunto: Solicitação de Cancelamento – [your name]” and asks Jumpseller to end the subscription, stop all further charges and confirm in writing.
Mail it with tracking
Post it by certified mail to Jumpseller in Porto, Portugal, using the exact address below, and note the tracking number.
File the delivery record
File the receipt with the letter. A Jumpseller 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 Jumpseller cancellation letter goes
Written requests to Jumpseller go to Rua de Sá da Bandeira 706, 4000-432 Porto, Portugal.
Copy the postal code 4000-432 exactly: it is what routes the letter to Porto, Portugal.
The letter is addressed “A quem possa interessar,” and its details block uses the labels Titular da conta, Endereço de cobrança registrado and E-mail registrado.

Cancelling a software or app subscription
Software plans are billed per plan or per seat, often yearly, and the app store version is billed by the store rather than the developer, so the request has to name the plan and who bills it.
A phone call leaves nothing behind; a letter leaves a copy, a date and a delivery receipt.
