Research the company behind each intro email

A new email just arrived in my Gmail. Decide whether it's an introduction: someone connecting me with a person or company I haven't talked to before. If it isn't, stop and do nothing. If it is, research the person I'm being introduced to and their company: their role and background, what the company does, its size and stage, funding and investors, and any news from the last [90] days. Note anything that connects to [what I'm working on or looking for]. Write a short brief with who they are, why the introducer likely connected us, and [3] questions worth asking on a first call. Don't reply to the email. Tell me who the intro is to, who made it, and the single most useful thing you found.
