"Hello [first name],
I have sent emails and called [X] phone calls without getting in touch with you. You seem to be an extremely busy person, which I completely understand since your company is very successful which leads to you having a lot to do. That's why I am now recording this short personal video to you so that I can during 60 seconds introduce myself and the great value I can provide you and your company."

Send this vaam as a GIF in a new email to the person, together with the same text that is provided above. Finally, if you're connected with the prospect on LinkedIn, send a short DM with the following text:

Looking forward to hearing from you!"
