Berman runs a popular digital marketing channel on YouTube. He has also created a new program for driving sales with no ads called Email10k.

No single technique has brought more business to my company than cold email outreach. I sent over one million cold emails and made it the singular focus of my career so much that I founded an agency, Experiment 27, which specialises in enterprise outreach, cold emailing and cold calling.

I've been doing YouTube videos on B2B selling and cold emailing for two years. And since I started, I get "What do you think about my email script" emails every week. Eighty-five per cent of the time, I'm not able to help. Why? They forget to include the most important thing -- the subject line.

Alex has been featured on Forbes, Inc, Entrepreneur on Fire, Entrepreneur, and every other business magazine.
