Section Create pop-up forms discusses how design, trigger and automate around the form.
One option is to trigger the form to appear if the website visitor is in a HubSpot list.
Would like the option to trigger the form to appear if the company identified is in a HubSpot list (not contact related).
Concept: I create a active list of Companies without contacts. Should a company in that list visit our site, show the form in hopes the visitor will self identify. Their contact info is captured, then they are added as a contact associated with that company.
