Email-based personalization

When we released website-based personalization, we heard some of you asking to extend it to email as well, so you wouldn't have to ask a new question.

When setting up discovery questions, there's a new preset for fields called "email". When using this field, once the customer answers the question with their business email, the agent will fetch their website in the background and use it to personalize the demo further. This works similarly to our "website" preset, but with email!
