How to cancel Kiwify by mail
Start with your account details
Start with the name and email on the account and, if you have one, an account or customer number, so the request to Kiwify names the right account the first time.
Write the cancellation request
Kiwify 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.
Send the letter by certified mail
Take the letter to the post office and ask for certified delivery to 05424150 São Paulo. Keep the tracking number it gives you.
Keep the proof of delivery
Once the letter is delivered, the date on the receipt is the date Kiwify 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.
Where your Kiwify cancellation letter goes
Kiwify lists Rua Pais Leme 215, 05424150 São Paulo, Brazil as its mailing address.
Copy the postal code 05424150 exactly: it is what routes the letter to São Paulo, Brazil.
The database also lists Avenida do Estado Dalmo Vieira 4295, 88330695 Camboriú, Brazil for Kiwify. Use the first address above unless your agreement names this one.
Inside, the salutation reads “A quem possa interessar,”, followed by your details under Titular da conta, Endereço de cobrança cadastrado and E-mail cadastrado.

Before you cancel Kiwify, 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
Most subscriptions keep billing until someone tells the company to stop, and a dated letter is proof that somebody did.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
