How to know when to follow up

Follow up when there was a genuine open thread, a stated intention, or unfinished business — not simply because time has passed.

Following up at the right moment turns a nice conversation into an actual relationship.

What nobody tells you

  • Most people worry they'll seem too eager, when in reality most relationships die from under-following-up, not over-following-up.
  • A follow-up doesn't need a big reason — 'thought of you when I saw this' is enough.
  • The best window is usually within 24-72 hours, while the context is still fresh for both of you.

The basics

  • A genuine open thread — something specific was mentioned that invites a next step — is the strongest signal to follow up.
  • Explicit statements ('let's grab coffee sometime') are semi-promises people mostly want honored, even loosely.
  • Following up is about maintaining a thread, not manufacturing a reason from nothing.

The framework

Thread, Timing, Cost

Check whether there's a real thread to pull, whether the timing still makes sense, and whether following up costs the other person very little to respond to.

  1. 01

    Thread: was something specific left open — a recommendation, an intro, a plan?

  2. 02

    Timing: is it still relevant, or has the moment passed?

  3. 03

    Cost: does your message require minimal effort for them to answer?

The playbook

0/6

The conversation — what to actually say

Following up after meeting someone useful at an event

“Great meeting you at [event] — you mentioned the podcast on career pivots, would love the name if you remember it.”

Following up on your own promise

“As promised, here's that intro to Sam — no obligation, just thought you two would get along.”

Gentle nudge after silence

“No worries if this got buried — just floating it back up in case it's useful.”

The mistakes — what people get wrong

  • Following up purely because time has passed, with nothing specific to say.
  • Waiting so long the context has gone cold and the message needs re-explaining.
  • Making the follow-up a big ask right out of the gate instead of a low-effort touchpoint.
  • Chasing after someone has clearly signaled disinterest through repeated non-response.

Ask yourself

  • Is there an actual open thread here, or am I manufacturing a reason?
  • Would this message cost them very little effort to respond to?
  • Am I following up out of genuine interest, or anxiety about being forgotten?
