Como incluir o link de cancelamento de assinatura em um e-mail?

The unsubscribe link depends on the service that you use to send emails (such as UniSender, SendPulse, Mailchimp, etc.). Usually such services automatically include an unsubscribe link or allow you to insert a special tag, for example: {{unsubscribe}}, %UNSUBSCRIBE_LINK%, etc.

Por favor, esclareça como deve ser exatamente o link no suporte do seu serviço de newsletter.

If you are creating the email on the Tilda side, you can try using the link: {{UnsubscribeUrl}} - if your mail service supports it.
