Fred Wilson once wrote about the topic of how to introduce two people who don’t know each other via email. He called it the “double opt-in introduction.” He talks about the stuggles of email introductions when you’re dealing at scale. His solution (if I understand it correctly), which I think is more aspirational than achievable is for the introducer to send out emails in advance asking whether or not they want to be introduced. I like that. But for me personally the extra overhead of this means that I can’t do it 100% of the time. Here's my 2 cents.
