I've seen several helpful posts in the forum that describe the script required to restrict non-corporate emails when a user fills out a form. I'm wondering if there is a preference for B2B campaigns one way or the other for top of funnel list development? Is there any ROI to demonstrate that more revenue/pipeline is influenced by original source leads with corporate only email addresses? Or perhaps after lead scoring and nurturing corporate email addresses become a high quality MQL? I'd love to hear the feedback from Marketo Nation smart demand gen folks.
