Not going to criticize the advice, since I think there's a point to it. I will take issue with this, though:<p>> The three hours spent at a networking event could also be invested in emailing your customers<p>Please, no, entrepreneurs. Don't consider e-mail a magic customer builder. I dropped Twilio like a bad habit after their community manager e-mailed me three templates in as many weeks, reminding me that I had signed up for an account; I was developing something using their service, and instantly shelved the project once these started to roll in:<p><i>I’d like to introduce myself, I'm Danielle, Twilio's Community Manager, and I'm here to help out with any questions you may have</i><p><i>I wanted to drop a note to see how your experience with Twilio has been going.</i><p><i>Danielle here, I wanted to share a few more Twilio tips and tricks with you.</i><p>I'm all for an occasional e-mail or two, but when your company is in my inbox once a week, that's too much. That's not developing a relationship with me, that's trying desperately to keep me interested in your service. Find better ways to develop relationships with your customers aside from e-mail.
