The first 24 hours after an event decide everything

Most people leave an event with twelve new contacts and one good intention. By Thursday they remember four names, and by the following week they remember one. Nothing failed. There was simply no gap in the week for the follow-up, and follow-up is the entire point of attending.

Do it the same night, while it is still warm

Names fade faster than you expect, and the detail that makes a message credible is always a detail: the project they mentioned, the city they are moving to, the thing they were worried about. That detail survives about six hours. Use it or lose it.

• While you are still in the room, add one line to each contact: what you talked about.
• On the way home or before you sleep, send the message. Not tomorrow afternoon.
• Do not write a paragraph. Two sentences and a clear next step beat a warm essay.

Make the message about them

The weakest follow-up is the one that only reintroduces you. The strongest one proves you were listening. Compare:

Good to meet you at the summit yesterday. You mentioned the launch is in November and the bottleneck is onboarding emails — happy to send you the sequence we use if that helps. I will check in next week either way.

It is short, it is specific, and it gives them something before it asks for anything. It also puts no obligation on them, which is why they usually reply.

Give the next step one line

Vague contacts die quietly. A specific next step — a call, a document, an introduction, a date range — converts. If you cannot name a next step, say you will send one useful thing instead. That is a next step.

Log it once, then let it rest

Follow-up fails when it lives in three places: your notes app, a card in your bag, and your memory. Put each person in one list with one date attached — the day you will speak again. Then stop thinking about it until that day arrives.

What to avoid

• Waiting until you have something to ask for. That turns a relationship into a transaction.
• Copy-pasting the same message to everyone. People recognise it instantly.
• Sending your CV to someone you met for four minutes.
• Following up three times in a week. Once, then once again at a distance.
• Doing nothing because the event is over. The event was the easy part.

The follow-up is not admin. It is the part where the introduction becomes a relationship, and it takes less time than the event itself did.
