Follow-up frequency dilemma - how persistent is too persistent after initial contact?

Got ghosted after what I thought was a great first coffee chat. Followed up after 1 week with additional thoughts on their market insights - still nothing. Where’s the line between demonstrating initiative and becoming a nuisance? For those who successfully converted ghosts into mentors, what’s your staged follow-up cadence and content strategy that respects their time?

theyre not busy, ur not priority. send max 2 follow-ups then move on. real play? cc their junior analyst on 3rd attempt - 40% panic-reply rate when peers might see their unresponsiveness

sent 4 follow ups in 2 weeks… now blocked on Linkedin. wat do??? pls help

Structured sequence: 1) 24hr thank you with specific value add, 2) 7-day follow up sharing relevant industry analysis, 3) 14-day touchpoint inviting them to an event. Cease contact if no response. Successful re-engagement typically happens at 3-6 month intervals with new context.

Analysis shows 82% response probability drops below 5% after 3rd follow-up. Optimal cadence: 48hrs (35% RR), 10 days (22% RR), 21 days (11% RR). Include data points in second follow-up - 37% higher response vs opinion-sharing.
