Recently I used InMail (like email but you need to pay $30 per month and can send 3 of which per month via linkedin.com).
I told a company I can bring them 20k-30k extra sign up per month. That’s a $300 million dollar company. I explained (too long) about too many issues.
The inmail is simply “declined” with no explanation whatsoever.
Am I disappointed? Yes. But not a lot. Why? Because it’s more of the norm rather than exception.
I am a lawsy introverted networker. Quite often people say no to me.
