Most part of the sites that can be visualized on the WEB have forms that allow you to execute operations of registers for future mail and these data are stored and organized in a data base in order to bring to the user information on products and services through his electronic address.

Spam is the used term to mean e-mails which were not requested, that are generally sent to a great number of people.

When the content is exclusively commercial, this type of message is called UCE (Unsolicited Commercial email); besides being an unwanted email there is not the option to cancel its signature. With the high growth of Spam, this practice is being punished in severe way by the law. When filling a form, be sure about the destination and use of the data.

Considering all that, MacroBrasil Solutions created smart systems, in which the users of the sites will be able to prevent receiving such messages, even if you subscribe, each news that you receive in your email will bring the option to cancel the act of receiving, and if you click, it will automatically cancel the reception of these news and it will only be possible to receive them if you subscribe in the site of origin again.
