How to cancel Zapsign by mail
Note your account details
Before writing, collect the account email, the plan or product name and the invoice or order number from your latest receipt. Zapsign can only act on a request it can match to an account.
Put the request in writing
Zapsign is based in Brazil, so the letter goes out in Brazilian Portuguese, built from our Brazilian Portuguese template. Subject line: “Assunto: Solicitação de cancelamento – [your name]”. It asks for the subscription to end, for further charges to stop and for written confirmation.
Mail it with tracking
Send the letter to the Rio de Janeiro mailing address shown below by certified mail. Keep the tracking number safe.
Keep proof the letter arrived
File the receipt with the letter. A Zapsign 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.

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 mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
