What if I have an external website and it will only be used for opt-in forms and webinars? Will it send clients to my Console site?

You can place on your external website custom Opt-In forms created in the Console (in WEBSITE TAB > CUSTOM OPT-IN FORMS) with the code provided in the last tab of the custom Opt-in form wizard (Opt-In Code). People who subscribe will be included as prospects in your Console list and be taken to your Console website.
