I am doing a regional self-funded search and was going to reach out to some intermediaries (where I don't have a warm connection) with a cold email. My list has multiple people in the same organization and so I wanted to figure out whether I should contact just 1-2 folks or everyone on the list (in some cases its 5-6 people at the same firm).

If I go with just 1-2 people at a given firm, the question then becomes who I should target - most senior or mid-level executives. Selecting just 1-2 people is also a more time intensive exercise vs. email everyone on the list. I'd like to know how other folks have approached this issue and which strategy has worked better.
