Contacts provide the following functionality:
user-level activity reporting. (e.g. firstname.lastname@example.org opened/clicked an email and watched 100% of video A)
Tag management (ability to mark contacts based on activity/history/tasks, etc) This has nothing to do with the number of views. Our platform is not intended to email blasting which is why we are compatible with email providers and CRM/marketing automation systems.
First, import your contacts. Then, when you are sending personalized videos, include the recipient's email to get detailed tracking.
