The follow-up email is where a lot of good events undo their own goodwill. The day went well, guests left happy, and then a generic, slightly pushy message lands in their inbox two days later, addressed to no one in particular and clearly written for a list rather than a person. It gets deleted, and the warm impression you earned at the door cools a degree. A follow-up that people actually open is not a marketing exercise. It is the last touch of an event you ran with care, and it should feel like it.
There is a second, quieter dimension to this that most guidance skips: the follow-up is also a data question. You are emailing people because they gave you their address for a specific purpose, and what you say, and how often, has to respect that. A follow-up that people open is one that is both worth reading and entirely within the bounds of what they agreed to.
Send it because you said you would, not because you can
The first principle is consent, and it is not a formality. People gave you their email to attend your event, perhaps to receive their pass, perhaps to get the slides afterwards. That is the purpose they agreed to. A follow-up that matches that purpose is welcome. A follow-up that pivots into marketing for three other things they never asked about is a misuse of the address, and under GDPR it is also a problem.
So before you write a word, be clear on why you are allowed to send this email and keep the content inside that reason. If you told guests they would get the recording, send the recording. If you want to market future events, that is a separate consent and a separate conversation. Keeping the follow-up honest about its purpose is not just compliant, it is what makes people trust the next email you send. This sits alongside the wider discipline of GDPR for events without the panic.
Email people for the reason they gave you their address, and the next email gets opened too.
What gets a follow-up opened
The open happens before anyone reads a word, decided by who it is from and what the subject line promises. Both are easy to get wrong and easy to get right.
- A real sender. The email should come from your event or organisation by name, not a generic noreply nobody recognises.
- A specific subject. Say what is inside. "Your slides and photos from Thursday" beats "Thank you for attending" every time.
- Timing that fits. Soon enough that the event is fresh, not so soon it feels automated before people have got home.
- A clear single purpose. One reason for the email, stated plainly, not a bundle of asks competing for attention.
The sender name matters more than people expect. An email from a recognisable name, ideally on your own domain, gets opened because it is trusted. One from a shared, anonymous address gets filtered or ignored. That is partly a deliverability question and partly a human one, and it is the subject of emails that come from you, not a shared noreply.
Write it like a person, for a person
Once it is open, the email has a few seconds to feel worth reading. The fastest way to lose those seconds is to sound like a template. Generic warmth, a wall of text, three calls to action and a footer of social icons read as a broadcast, and people treat broadcasts accordingly.
A few habits keep it human:
- Lead with the thing they want, the slides, the photos, the recording, in the first line.
- Keep it short. Most follow-ups are twice as long as they need to be.
- Use the guest's name if you have it cleanly, but never fake personalisation you cannot back up.
- Have one clear next step, and make it easy to ignore without feeling nagged.
- Sign it from a person or a named team, not from a faceless system.
The email that performs is usually the plainest one: a short note that gives people what they were promised, from someone they recognise, with no hard sell. It respects their time, which is exactly why they read it.
Respect the unsubscribe and the silence
Two signals tell you whether your follow-up is welcome, and both deserve respect. The first is the unsubscribe. Make it obvious and act on it immediately. A buried or ignored unsubscribe is both bad manners and a compliance failure, and it teaches people to mark you as spam instead, which damages every email you send afterwards.
The second signal is silence. If people are not opening, the answer is not to send more or to send louder. It is to send less, and better, and only when you genuinely have something for them. Treating attention as a resource you can spend freely is how a healthy list goes stale. Treating it as something earned each time is how you keep one worth emailing.
A good last touch
The follow-up is the final thing your event does, and it should carry the same care as the first. Send it for the reason people gave you their address. Make it come from a name they trust, with a subject that tells the truth about what is inside. Keep it short, human and easy to walk away from. Honour the unsubscribe and read the silence. Do that and your follow-ups get opened, your list stays healthy, and the goodwill from the door survives the trip to the inbox.
CheckInHub sends event emails from your own brand and domain, against a guest list you hold for a clear purpose, so the follow-up lands as the considered last word of a well-run event rather than the moment you lost the room.
