How to follow up after a networking event (without being a pest)

The event ended, you got home with six new names, and now the blank message field is staring back. Every draft reads needy or salesy, so you close the app and tell yourself tomorrow. Good follow-up is mostly structure, not talent: write inside 48 hours, anchor the message to one moment, ask for one small thing.

The 48-hour rule is about memory, not manners

Hermann Ebbinghaus (1885) measured how fast new material slips away, and the shape of his forgetting curve has held up in modern replications (Murre & Dros, 2015): the steepest loss happens in the first hours and days, then the curve flattens. Conversations at a networking event are exactly the kind of weakly-anchored material the curve punishes. No repetition, no written record, a dozen competing conversations on the same evening.

The part most people miss is that the curve runs in both directions. You are forgetting them — what they said, what they were stuck on, what you offered. And they are forgetting you at the same rate. Inside 48 hours you are still the person who had the strong take on freelance pricing. By day five you are someone from that event, maybe the one in the grey jacket? The 48-hour rule isn’t a politeness deadline. It’s the window in which your message lands on a warm memory instead of having to rebuild one.

Two practical consequences. First: the quality of your follow-up is mostly decided before you write it, in the 30 seconds after the conversation when you do — or don’t — capture what was said. If you tend to lose those details, the fix is a note-taking habit, and we’ve written up how to remember details about people separately. Second: if the window has already closed, follow up anyway. A late message just has to work harder — more specifics, more context — because it can’t assume any shared memory is left.

What to say: the three-part message

Strip every good follow-up down and the same skeleton appears. A hook — one specific moment from the conversation, so the reader places you within the first line. A give — the thing you promised, or something relevant you offer unprompted. An ask — one low-stakes next step, framed so that declining is easy. Five sentences is usually enough; it’s a touchpoint, not a pitch deck.

Here is the skeleton with flesh on it, peer-to-peer version:

Hi Dana — still thinking about your point that most founders hire a salesperson a year too early. Here’s the essay I mentioned that makes the opposite case, curious where you land: [link]. If you’re up for it, I’d happily trade notes on first hires over a 20-minute call sometime in the next couple of weeks — no agenda beyond that.

And the version where you want something, written so it doesn’t smell like it:

Hi Tomás — good to meet you at the API panel; your war story about the migration that took 14 months stuck with me. I sent you the checklist we used for ours, as promised. Separately: if your team ever opens up that integration question again, I’d love a shot at being in the room. No urgency on any of this.

What both have that the typical follow-up lacks: not a single sentence could have been sent to anyone else. “Great to meet you! Let’s keep in touch!” is the message equivalent of a dead handshake — it costs the reader more energy to answer than it gave them reason to.

Sequencing the second and third follow-up

One message rarely settles anything. People travel home, dig out of inboxes, forget with the best of intentions. A sequence keeps you present without becoming pressure — as long as every touch carries something new. “Just bumping this” carries nothing.

1. Within 48 hours — the anchor message

   The three-part message above: hook, give, ask. This is the only step with a hard deadline, because it’s the only one that depends on shared memory still existing. If you met fifteen people, write the three to five that matter first and let the rest be LinkedIn connections with a one-line note.

2. Day 7–10 — the value nudge

   If the anchor got no reply, send one short follow-on that adds something instead of asking again: a link that matches their problem, a relevant intro, a thought that extends the original conversation. One or two sentences. The subtext is generous and unbothered — no reference to the unanswered message, no hurt feelings between the lines.

3. Week 3–4 — the context re-entry (optional)

   Only if something real happens: their company announces something, you hit the exact problem you discussed, you meet someone they should know. Real context is the difference between persistence and pestering. If nothing real happens, this step simply doesn’t exist for that contact.

4. After that — park it into a cadence

   No reply after two or three genuine touches means the timing is wrong, and timing is not a thing you can push. Move the contact out of your active queue and into a slow follow-up cadence — a check-in every few months when you genuinely have something. A networking tracker handles this at spreadsheet scale; a personal CRM like Endearist does the same with reminders, so parked contacts resurface on their own instead of depending on your memory.

When silence is fine

Here’s the reframe that takes the sting out: silence after a networking follow-up is almost never a verdict on you. Boothby, Cooney, Sandstrom and Clark (2018) ran a series of studies on what they called the liking gap — after conversations, people consistently believed their partners liked them less than those partners actually reported. Your read of “they didn’t reply, so the conversation must have meant nothing” is being generated by exactly the miscalibrated instrument the liking gap describes.

The more likely explanations are boring: your message arrived in the post-event inbox avalanche, they flagged it for a thoughtful answer that never got written, the project you discussed got shelved. None of these are improved by a third unanswered message — but none of them close the door either. Some of the most useful professional relationships start with a follow-up that went nowhere and a second contact, months later, with a real occasion. That second contact has its own craft, and how to reconnect after losing touch covers it.

There’s also a quieter case where silence is fine: yours. Not every pleasant conversation creates an obligation. If nothing was promised and nothing is open, filing the contact with a good note — and no message at all — is a legitimate, even respectful, outcome. Follow-up is a tool for the conversations that earned it.

If you met more than a handful of people

Everything above assumes you can hold the queue in your head. Past five or six contacts, you can’t — the anchor messages collide with the day-7 nudges, and the people you most wanted to write are exactly the ones who slip. At that point the bottleneck stops being phrasing and becomes process: getting the pile of cards, scans, and LinkedIn adds into one prioritized list with dates attached. That is its own evening of work, and we’ve broken it down in how to organize contacts after a conference.

The short version holds either way: two days, three parts, three touches, then peace. Most people fail follow-up not by writing badly but by writing late or never. Beat the curve once and the rest is just keeping promises.
