How to cancel Nao Inviabilize by mail
Gather your account details
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Nao Inviabilize is the easiest one to set aside.
Draft the request
Postbye drafts the request in Brazilian Portuguese, the language of Brazil, with “Assunto: Solicitação de cancelamento – [your name]” as the subject line. It asks Nao Inviabilize to close the subscription, stop billing and confirm in writing.
Send it by certified mail
Address the envelope to Nao Inviabilize, São Paulo, exactly as printed in the next section. Certified mail gives you a tracking number and a delivery record.
Hold on to the receipt
Once the letter is delivered, the date on the receipt is the date Nao Inviabilize was told. Compare it with your statements over the next billing cycle.
With Postbye, steps 2 to 4 take about two minutes of your time.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
