The post-event follow-up email most organisers send is wrong

I run a lot of post-event audits with organisers. The one document I ask for first is the post-event email. It is the cheapest part of the whole event and the part almost nobody puts real thought into.

Nine times out of ten, what I get back is the same email. A hero image from the conference. A line that says 'thank you for being part of an amazing three days'. A couple of speaker highlights. A survey link. Save-the-date for next year. End.

That email is doing almost none of the work it could be doing. And it is where most of the networking value of the event quietly leaks away in the 48 hours after the doors close.

The default email does almost nothing

Let me be direct. The generic thank-you email is a goodwill exercise. It is not a networking tool, not a retention tool and not a revenue tool. It exists because organisers feel they should send something, and because marketing templates come pre-loaded with one.

The cost of sending a generic email is not zero. It trains attendees to delete your communications without reading them. It burns one of the two or three touchpoints you will have with that attendee between this event and the next. And it quietly signals that the event was a one-shot performance, not an ongoing relationship.

That is a lot of downside for an email most teams do not even remember sending.

What the email should actually do

A good post-event email does three jobs. It helps attendees remember who they met, it gives them a specific reason and hook to follow up, and it makes the next event feel inevitable rather than optional.

Notice what is not on that list. It is not 'thank attendees for coming'. It is not 'showcase the highlights'. It is not 'gather feedback via survey'. Those things can happen in the email, but they are side effects of doing the three core jobs well.

If you start from the three jobs and work backwards, you end up with a much shorter and much more useful email than the template most teams inherit.

The three things that matter

One. Remind them who they met. By name. Specifically the matched or introduced contacts, not a generic attendee list. 'You were matched with Maria from Acme and Priya from Bolt on day one. Here are their LinkedIn profiles if you would like to stay in touch.' That single paragraph does more networking work than the rest of the email combined.

This is only possible if the event actually tracked those matches. If you ran unstructured networking and have no record of who spoke to whom, the email cannot do this job and the best you can do is give them an attendee list. That is the retrospective argument for building the matching data in the first place, which I covered in more detail in the piece on what your registration form already knows about your audience.

Two. Give them a hook. Do not just list the people they met. Remind them what the conversation was about or give them a reason to pick it back up. 'Maria mentioned the pilot she is running with the transport team - the report she referred to is now public.' 'Priya asked about the vendor you use for payroll - here is the name you did not have at the time.' A specific hook turns a polite LinkedIn request into a real follow-up.

Three. Make the next event feel inevitable. Not 'save the date for 2027'. Something closer to: 'we run a small follow-up session in six weeks for attendees who want to compare notes on the themes from this one' or 'our next event is open for early registration from members this week'. The next event should feel like the continuation of the conversation the attendee just had, not a separate thing to reconsider from scratch. This matters especially for association member networking events, where the post-event note is often the most-read communication the member gets all year.

When to send it

48 to 72 hours after the event closes. Earlier and attendees are still in airports or catching up on email. Later than a week and the conversations feel cold. Day two or three is the sweet spot.

The short 'thanks for coming' note sent within 24 hours is fine as long as it is not the only communication you send. Think of that as a receipt, not as the substantive follow-up. The real work happens in the second email.

The template I actually use

Here is the shape I use when I rewrite these emails for organisers. It is deliberately short. Paste, adapt, cut anything that does not do one of the three jobs.

Subject: Who you met at [event name] - and what might be worth picking up

Hi [first name],

Quick note, three days on from [event name]. Three things, then I will let you get on with your week.

1. Who you met. You were matched with [contact 1] from [company] and [contact 2] from [company]. Their LinkedIn profiles are here: [link] [link].

2. Something worth following up on. [One specific, personalised hook based on what the matches talked about, or a shared interest from their registration.]

3. What is next. [One specific next step - a follow-up session, an open registration window, a community channel - not a generic save-the-date.]

If you have a spare two minutes, [survey link] would help us make the next one even more useful.

Thanks again for being there, [organiser first name]

That is roughly 150 words. No hero image, no speaker highlights, no sponsor logos. On a phone it fits in a single screen. It does all three jobs and it treats the attendee like an adult.

The design-heavy template is not wrong - there is a place for it - but it should be a separate email sent a week later to the whole audience, not the substantive follow-up to the people you actually want to deepen a relationship with.

How to measure whether it is working

Open rate is the usual metric and it is the wrong one. It tells you whether the subject line worked, not whether the email did its job. Track two better things.

Reply rate. How many attendees replied to the email - with a thank you, a follow-up question, or an introduction to someone else. Genuine replies are the strongest signal that the email created real conversation. A thank-you reply is still a reply.

Next-event registration rate, split by whether the attendee received a personalised follow-up. This is the metric that tells you whether the email is doing commercial work. If attendees who got the personalised version sign up for the next event at a meaningfully higher rate, the template is earning its place.

For a fuller picture of what to actually measure post-event, we wrote a full piece on how to tell if your event networking actually worked. And if the 'reminding attendees who they met' job sounds obvious but hard in practice, that is exactly what the pre-event matching data is for - it is the same data that makes the follow-up possible.
