Thanks for the info Kim, but I'm not sure either of those fix my problems.
As to your first post, I believe the "Fills out form" is used exclusively for Marketo forms. This form is not a Marketo form, but a form created by our engineers on our website. We have to use our SOAP API integration to bring leads over from that form. If the "fills out form" can be used for non-marketo forms, please correct me!
Regarding your second post, it essentially defeats the purpose of doing a "trigger campaign". If I need to manually transfer leads from a smart list to a static list, than that is no longer a "triggered campaign" and would not send emails when a lead is added to the list.
