We are just starting a new campaign using personalized video. We have built a tool called Switch Merge that allows us to merge the data we have in our CRM and inject that right into a video. This means that we can email a cold prospect a video that is personalized just for them.
You can see and example for a fictitious lead at HP called Toni. If this video was sent to another person at a different company then about 15 different things would change. (name, logos, etc)
This video explains how we see this tool helping sales people.
We don't have much data yet but we are expecting that a personalized message will help increase the number of meetings we book vs just using a standard video. We will know more in 4 weeks.
