sendmachine.com é seguro?

This site is an email marketing service provider (like Mailchimp). They have zero tolerance for spam (http://www.sendmachine.com/antispam.html?lang=en) but occasionally some new clients manage to send some (by mistake or bad will). In this case the spam outbreak is promptly stopped and every unsubscribe is honoured. I've used sendmachine myself so I know what I'm talking about.

Spam to random email addresses.
