Some of the best moments of my career came from contacting someone in the industry with a cold email. These include but not limited to my first consulting gig, business partnerships, and good friendships.
I know the feeling of contacting someone out of the blue. I still have anxiety around this. But at the end of the day, if you send a friendly email, the worse that can happen is the recipient ignores the message.
So I want to let you know I love getting email. The best address for me is email@example.com. I'll do my best to read and reply to your message.
