You (and many technical people) do, but most people don't, that's why it works. Reminds me of this comment I saw a while ago:
https://news.ycombinator.com/item?id=25825917#25828439> On HN, people hate cold emails. In real life, I've found that most people will respond or ignore. Like a tiny minority will act like you killed their mother, but that's life.
> I know you know this, if you're in sales, but I, like many other engineers who read this forum was overly cautious when I first started speaking to people because I anticipated that 99/100 would be upset at having to talk to me.
> The truth was that 99/100 were willing to speak to me and listening to HN and Reddit set me back farther than I expected until I unlearned that lesson.
> So I'm saying this for the benefit of all those other engineers like me.
