How to Build an Email List from Your Events

·BookOrWaitlist Team·6 min read

Every event you run generates interest beyond the people who actually attend. Someone sees your Instagram post but doesn't register. Someone tries to sign up but the event is full. Someone attends once but doesn't come back.

Most of that interest disappears because there's no system to capture it. Each event starts fresh, promoting to cold audiences, hoping the algorithm cooperates.

Building an email list from your events changes this. Instead of starting over each time, you're growing an audience that you can reach directly, without depending on any platform.

Why an email list from events works differently

An email list built from event registrations has two qualities that make it unusually effective:

The people on it already raised their hand. They didn't just follow you on social media. They left their contact info because they wanted to attend something you organized. That's a much stronger signal of interest.

You can reach them directly. No algorithm decides whether they see your next announcement. When you email your list, it lands in their inbox. Open rates for event-related emails from organizers typically run 35 to 50%, compared to 15 to 20% for general newsletters.

Three places to capture contacts (most organizers only use one)

1. At registration

This is the obvious one. Someone signs up for your event, you get their email. Most organizers already do this.

The key improvement: make sure you capture contact info before sending people to payment. If you link directly to a payment page, you only get the details of people who complete the purchase. A landing page that collects contact info first, then redirects to payment, captures everyone who was interested, including those who didn't finish paying.

Tools like BookOrWaitlist handle this automatically.

2. When your event is full

This is the one most organizers miss entirely. Your event sells out. The next person who tries to register sees "sold out" and leaves. You never know they existed.

Instead, switch your registration page to waitlist mode. It still collects contact info, but shows a message like: "This session is full. Leave your info and we'll let you know when the next one opens."

Waitlist contacts tend to be your best future attendees. They already demonstrated enough interest to try signing up. When your next event opens, email them first.

3. After the event

Send attendees a short follow-up email within 48 hours. Thank them, ask for one piece of feedback ("What was the most useful part?"), and include a line like: "Want to hear about upcoming sessions? Just reply 'yes' to this email."

This confirms their email is active and re-establishes the connection while your event is fresh in their mind.

Growing your list over time

Here's what a realistic growth trajectory looks like for a small workshop organizer:

First event: You capture 20 contacts (15 attendees + 5 waitlist).

After 3 months of monthly events: Your list is around 70 to 90 people, assuming some overlap between events.

After a year: Somewhere between 200 and 500 contacts, depending on your event frequency and audience size.

These aren't huge numbers. But for a small workshop business, a list of 300 engaged people who open your emails is enough to fill events consistently without relying on paid advertising or social media algorithms.

The key word is "engaged." A smaller list of people who actually open your emails and book events is far more useful than a large list of people who ignore you.

What to send between events

The biggest mistake organizers make with their list: going silent for weeks, then sending a promotional blast when the next event opens. This trains people to ignore your emails.

A better pattern:

Right after the event (within 48 hours): A thank-you email with one useful thing. Could be a link to a resource related to what you taught, a photo from the event, or a quick tip. Keep it short.

Example subject line: "Thanks for Saturday. Here's the recipe list."

Between events (once every 1 to 2 weeks): Share something genuinely useful related to your topic. If you teach pottery, share a glazing technique. If you run cooking classes, share a seasonal recipe. If you organize yoga workshops, share a quick morning routine.

Example subject line: "3-minute stretch you can do at your desk"

When your next event opens: Announce it to your list before posting publicly. This rewards your subscribers and often fills a chunk of spots before you even promote on social media.

Example subject line: "Next cooking class: March 15. Spots open now."

The ratio that works: roughly 3 value emails for every 1 promotional email.

The tools you'll need

Your setup can be simple:

  1. A landing page with contact capture for event registration. BookOrWaitlist handles this, or any simple landing page tool.
  2. An email marketing tool to store contacts and send emails. Mailchimp (free up to 500 contacts), MailerLite, or ConvertKit all work. This is where you'll manage your list, create segments, and send campaigns.
  3. A connection between them. Export contacts from your registration tool and import them into your email tool. If you want automation, services like Zapier can connect the two so new registrations flow automatically into your email list.

A note on what BookOrWaitlist does and doesn't do: we capture contact info (emails and phone numbers) and let you export them as CSV. For sending email campaigns, segmenting your list, or setting up automated sequences, you'll need a dedicated email marketing tool. We don't try to be an email platform because tools like Mailchimp and ConvertKit do that job much better.

When the list starts working for you

The shift happens somewhere around 100 to 200 engaged contacts. Instead of each event being a fresh marketing effort, you email your list and a meaningful portion of spots fill within hours. You spend less time promoting and more time actually running your events.

This doesn't happen overnight. It's the result of consistently capturing contacts at every event, sending useful content between events, and treating your list as something worth maintaining.

Start capturing contacts at your next event. The list you build this year will be the thing that fills your events next year.
