The majority of replies to cold outreach come from follow-ups, not the first send. Almost everyone stops after one. That gap is the cheapest advantage available to you, and it requires no additional skill.
A sequence that respects them
- Day 3: add something new — a detail you noticed, not "just bumping this."
- Day 8: change the angle. A different problem, or a shorter ask.
- Day 16: the close-out. One line saying you will stop, no guilt.
Every follow-up must add value on its own. "Just checking in" is a request for their attention that offers nothing back, and it teaches them to ignore your name.
