If you're doing cold outreach at any volume, you know the pain of researching personalized first lines. This skill takes a prospect list and generates unique openers based on LinkedIn activity, company news, funding rounds, mutual connections, and other signals. It organizes everything by personalization type (congratulations, observations, shared interests) and gives you multiple first line options plus full email templates for each prospect. The format is detailed, maybe more than you need, but you can always strip it down. Claims to save 10+ hours per campaign, which tracks if you're manually researching 100+ prospects. Worth trying if you're tired of "I was on your website" personalization that fools nobody.
