Do I consider cold calls good or effective?
No, not really. The math works out like this: you could call about 50 people in an hour and maybe have real conversations with 10 of them. If you spend that same hour setting up a cold‑email system, you can build infrastructure that lets you reach roughly 50,000 people. Comparing the two, 1 hour of calls reaches 50 people, while 1 hour of email outreach can reach 50,000. That’s a 1‑to‑1,000 ratio. In reality, emails are probably 50‑100 times less effective per contact than a call, meaning you need to send about 150‑times more emails to equal the effectiveness of a single call. Even so, per unit of time cold emailing ends up being roughly 20 times more effective than cold calling.
