Email for Events: Nine Emails and the Gap Between Registration and Attendance

An event organiser needs nine emails, and most of them solve one problem: getting a registrant to actually turn up. The gap between registration and attendance is the core problem of the industry, particularly for free events: the decision to sign up came easily, so changing your mind comes just as easily. Below is the email map and which of them genuinely moves attendance.

The core problem of the industry

The cause of the gap is the price of the decision. A purchased ticket creates an obligation: the money is spent, and not attending means losing it. A free registration creates nothing: someone clicked a button between other tasks and two weeks later does not remember it.

Hence the practical conclusion that shapes the whole scheme: event emails work not on persuasion but on holding an intention. The person already agreed to come; the job is to stop that decision dissolving in the time before the event.

The second difference is a hard tie to time. An abandoned cart email can go out a day late and still work. An event email sent after the start is entirely useless.

A map of nine emails

The full set looks like this. Five emails go out before the event and four after.

Note that three of the nine go to people who will not attend or already have. That is not waste — those are what turn a one-off event into an audience.

Why the confirmation decides a lot

The registration confirmation is the one email certain to be opened, because it is expected. Hence the rule: everything important belongs in it rather than in what follows.

• the date and time with a time zone, if the event is online
• the joining link or the address with a map link
• an add-to-calendar button — the only reliable way to remind anyone
• what will happen at the event in two or three lines
• how to cancel if plans change

The add-to-calendar button matters more than everything else combined. An email gets lost in an inbox; a calendar entry reminds by itself, and at the right moment.

The cancellation point is not a formality either. Someone who cancels in advance frees a place and gives you an honest attendance forecast. Someone who simply does not appear gives you nothing.

Three reminders instead of one

One reminder is not enough and three are too many if they are identical. What works is a scheme where each reminder carries its own information.

Three days before — a reminder asking to confirm attendance. This email collects cancellations while they are still useful and simultaneously raises attendance among those who confirmed: confirming creates the very obligation that registration did not.

A day before — the practical email. How to get there, where the entrance is, when to arrive, what to bring. For an online event, how to test the connection in advance and what to do if the link fails.

Two to three hours before — a short email with only the link or the address. No programme, no descriptions: the person has already decided to come and needs one action.

The day-of email

The day-of email is the shortest in the whole map, and deliberately so.

It gets read on the move: travelling, between tasks, five minutes before the start. Anything that is not a link or an address gets in the way. A programme, a welcome paragraph, a full-width logo — all of it pushes the needed thing further down.

A separate device for online events is an email to latecomers half an hour after the start. Some people forget or get distracted, and a reminder while the event is running brings them back. For an in-person event such an email is pointless.

No-shows are not lost

People who did not attend are not a lost audience. They showed interest, they simply could not make it.

An email the next day with the recording solves two things at once: it gives them what they registered for and keeps you in their field of view. Send it without reproach — "sorry you missed it" reads as a complaint and lowers the chance of them attending next time.

• the recording or materials without conditions and without registering again
• a three-point summary of the key content for those who will not watch
• the date of the next event, if it is known
• no question about why they missed it — it rarely produces a useful answer

Materials and the next event

The email to attendees goes out the same evening, while the event is fresh. Materials promised during the session must arrive then, not a week later, or the interest has already cooled.

The invitation to the next event goes out one to two weeks later. Earlier and it competes with the impression of the last one; later and it loses the connection.

The most effective content for that email is not the programme of the new event but a reminder of what was useful at the previous one. People decide to attend a second event based on their impression of the first, not on a description of the second.

And a technical note, critical in this industry. The day-of email is opened almost exclusively on a phone, often while travelling and on a weak connection. The joining link must be a large button near the top rather than a line in the middle of the text.

The Mailvex library includes event templates: registration confirmations, event reminders, materials emails and invitations. The day-of template is deliberately short, and your brand kit applies to every email at once.

Frequently asked questions

How many reminders should go out before an event?

Three, but different ones: three days before asking to confirm, a day before with practical information, and two to three hours before with the link or address. Three identical reminders annoy; three different ones work.

What matters most in a registration email?

The add-to-calendar button. An email gets lost in an inbox; a calendar entry reminds by itself at the right moment. The rest — date, link, programme — is needed too, but the calendar moves attendance most.

Should I write to people who did not attend?

Definitely. They showed interest and simply could not make it. Send the recording without conditions and without reproach: "sorry you missed it" reads as a complaint and lowers the chance of them coming next time.
