Personalized video marketing

“What's in a name?” Possibly quite a lot when it comes to personalized marketing.
Several months back I received a marketing email from Sprinklr that was rather ironic given its message about effective use of data. It opened like this: “ Hi {lead.First Name:default=}.”  Obviously, something went wrong, and I saw the code rather than my name.
Of course, personalized emails are not all that unusual any more, so some marketers have upped their game with personalized video. After receiving the “A Dog's Purpose” video (above) — in a correctly personalized email — I contacted Adgreetz's co-founder and CEO Eric Frankel about what data is used for this kind of personalized video marketing, and how the video was delivered to people who are 1) dog owners, and 2) have a dog of that particular name?
