I put on my website a "new lead" form and additionally I configured a workflow to send a "thankyou" email when a new lead comes from website and the rule should be applied only when a lead is created and not edited. But in my case, I set in config to aprove each lead before, in order to avoid spammers. The problem is that the email has not been sent and I have no idea why.
So, my point is: when a lead needs to be approved, is it considered as a new lead from the "workflow view"? Can we apply a rule to send a "thankyou" email only when that lead has been approved?
Additionally, is there a difference between using a workflow to send a "thankyou" email and using an auto response rule for the form? Why use one or other?
