Tactics for Targeted Outreach Without Bombarding Companies

Hey ya'll. Let's say I have a table with lots of people in it. And sometimes these people work at the same company. In the past I have reached out to everyone at once, but for this client we want to only reach to 1 or a few at once, rather than bombard the company. What is the best way to tactically go about this ? I guess I would score each lead based on ICP relevancy or seniority etc. Once I had the score, though, how would "tactically" implement this if I was sending to SmartLead campaign? Only leads with a score above x get added ? what gets me confused is how I would launch the rest of the leads into the campaign, without double-sending to a company where we had already gotten a positive response. Thanks for anyone's help on this 🙏🏼
