Re: Auto-response emails to those whom visited out companies site
Hi Paul,
You would need for that lead to fill out a form and become "known". If it's a known lead you can definitely set up triggered smart campaigns off of certain actions to send emails. Unfortunately new or anonymous leads we wouldn't have enough info to send to.

To Josh's point, definitely apply constraints to your email campaign such that an individual lead won't trigger a specific email more than once, or more than once per a decent length of time
