There's no shortage of opinions in this world. Sadly, most of them are misguided and even incompetent. People see the world as they are, and think everybody else is like then. "But I never click on ads!", "Nobody shares their email!", "I think it should be blue" and so on.

You are not the world. You are not your customer. Hence you cannot make conclusions about user behavior based on your personal preferences. It's very natural to want to, but try to resist.

Instead, focus on evidence based marketing. Talk to your audience - the answers you need are outside of your office.
