How to Build an Event Mailing List From Scratch

Every event organiser knows they should have a mailing list. Yet most start from zero with no subscribers, no strategy, and no idea where to begin. The good news is that building a list from scratch is entirely achievable, even if you have never sent a marketing email before.

This guide walks through the practical steps to go from an empty spreadsheet to a thriving, engaged mailing list that sells tickets for every event you run.

Why a mailing list matters more than followers

Social media followers are rented. Your mailing list is owned. An Instagram algorithm change can halve your reach overnight. A mailing list lands directly in someone's inbox regardless of what any platform decides to do.

For event organisers specifically, email converts better than any other channel. A subscriber who opens your email is actively interested in what you do. Compare that to a social media follower who might scroll past your post without registering it.

If you are starting from zero, do not be discouraged. A list of 200 genuinely interested subscribers will outsell a list of 5,000 disengaged ones every time. Quality matters far more than size.

Step 1: Choose your email platform

Before you can collect email addresses, you need somewhere to store them and something to send with. Pick a platform and set it up properly from the start.

For event organisers starting out, these are the best options:

• MailerLite — Free up to 1,000 subscribers. Clean, easy to learn, and solid automation features.
• Mailchimp — Free up to 500 contacts. Well-known, loads of templates, and integrates with almost everything.
• Brevo — Free with up to 300 emails per day. Good if you want marketing and transactional emails in one place.

Set up your account, create your first list, and configure your sender name and email address. Use a recognisable sender name — your event brand or promoter name, not a personal email.

Step 2: Create a signup form that converts

Your signup form is the front door to your mailing list. It needs to be simple, fast, and give people a reason to subscribe.

Keep it short

Ask for the minimum information you need. For most event organisers, that is:

• Email address (required)
• First name (optional but useful for personalisation)
• Location or event interest (optional, useful for segmentation later)

Every additional field reduces signups. You can always collect more information later.

Write a compelling reason to sign up

Nobody subscribes to "our newsletter." They subscribe to get something specific. Frame your signup around what the subscriber gets:

• "Get early access to tickets before they go on general sale"
• "Be first to hear about new events in [city]"
• "Subscriber-only discounts and priority booking"
• "Join 1,200+ event fans who get our weekly picks" (once you have the numbers to back this up)

Where to put your form

• Your website homepage — Above the fold or as a sticky bar at the top or bottom.
• Event listing pages — Below the event description, especially on sold-out events where people might want to know about the next one.
• A dedicated landing page — A standalone page at something like yoursite.com/join that you can link to from social media bios and posts.
• Pop-ups — Use with caution. A well-timed exit-intent popup can work, but aggressive pop-ups annoy people. If you use one, make sure it only appears once per visitor.

Step 3: Capture emails at checkout

This is the single most effective list-building tactic for event organisers, and it is often overlooked. When someone buys a ticket, they are already engaged with your brand. Adding a simple opt-in checkbox during checkout captures these high-value subscribers with almost no effort.

The checkbox should say something clear like: "Yes, keep me updated about future events from [Your Brand]." Under GDPR, this must be unchecked by default — the buyer actively ticks it to opt in.

Tickts includes a checkout opt-in feature that makes this straightforward. If you are using another ticketing platform, check whether it supports mailing list integration or export of opted-in buyers.

Over time, checkout opt-ins will become your biggest source of quality subscribers because these are people who have already spent money with you.

Step 4: Use QR codes for offline capture

Not all list building happens online. If you run physical events, you have a captive audience of people who are already fans. Capture their details while they are in the room.

How to set this up

1. Create a mobile-friendly signup form or landing page.
2. Generate a QR code that links directly to that form (use a free tool like QR Code Generator or your email platform's built-in QR feature).
3. Print the QR code on table cards, posters near the bar, screens behind the stage, or on the back of physical tickets.
4. Add a short call to action: "Scan to get early access to our next event."

A QR code at the bar of a 300-person event, with a small sign saying "Scan for 10% off your next event," can easily capture 30 to 50 new subscribers in a single night.

Step 5: Leverage social media to drive signups

Social media is temporary. Email is permanent. Use your social reach to funnel people into your more permanent channel.

Tactics that work

• Bio link — Add your signup page URL to your Instagram, TikTok, and Facebook bios. If you use a link-in-bio tool like Linktree, make your mailing list signup the top link.
• Instagram Stories — Use the link sticker to send people to your signup form. Post a Story with "Want early access to tickets? Join our list" and a direct link.
• Facebook posts — Periodically remind your followers that email subscribers get first access. Share a screenshot of a previous "early access" email as proof.
• Pinned posts — Pin a signup prompt to the top of your X profile or Facebook page.
• Giveaways — Run a giveaway where entry requires joining your mailing list. Two free tickets makes a great prize. Be aware of Gambling Commission rules: if entry requires purchase, it is a lottery. Email signup alone is fine.

Step 6: Make GDPR compliance easy

UK GDPR is not as scary as it sounds, but you do need to get the basics right from day one. Fixing compliance problems on a list of 5,000 is much harder than setting it up properly on a list of 50.

The essentials

• Active opt-in only. Every subscriber must actively choose to join your list. No pre-ticked boxes, no adding people without consent, no importing email addresses you found somewhere.
• Be clear about what they are signing up for. "Marketing emails about our events" is fine. Vague language like "updates" is risky.
• Include an unsubscribe link in every email. Your email platform does this automatically, but double-check it works.
• Keep consent records. Your email platform stores when and how each person subscribed. Do not delete these records.
• Honour unsubscribes immediately. Legally you have a short window, but practically it should be instant. All major email platforms handle this automatically.

The soft opt-in exception

Under UK PECR (Privacy and Electronic Communications Regulations), if someone has bought a ticket from you, you can email them about similar events without explicit marketing consent, provided you offered an opt-out at the point of purchase and include an unsubscribe option in every email. This is called the "soft opt-in" and it is a valuable tool for event organisers.

Step 7: Keep your list healthy

A mailing list is not a "set and forget" asset. It needs regular maintenance.

Remove inactive subscribers

If someone has not opened any of your emails in six months, they are dead weight. They drag down your open rates, hurt your sender reputation, and can cause deliverability problems. Run a re-engagement campaign ("Still want to hear from us?") and remove anyone who does not respond.

Handle bounces

Hard bounces (invalid email addresses) should be removed immediately. Most email platforms do this automatically. Soft bounces (temporary delivery failures) are usually retried, but if an address soft-bounces repeatedly, remove it.

Watch your unsubscribe rate

A normal unsubscribe rate is 0.1% to 0.3% per send. If it spikes above 0.5%, something is wrong — you are emailing too often, your content is not relevant, or you are reaching the wrong people.

Realistic growth expectations

Building a list takes time. Here is what reasonable growth looks like for a UK event organiser starting from zero:

• Month 1–3: 50–200 subscribers (mostly from checkout opt-ins and personal network)
• Month 3–6: 200–500 subscribers (adding social media capture and at-event signups)
• Month 6–12: 500–1,500 subscribers (compounding from multiple events and consistent effort)
• Year 2+: 1,500–5,000+ subscribers (organic growth accelerates as your events grow)

These numbers assume you are running events regularly and actively promoting your list at each one. The key is consistency. Add a signup form today, turn on checkout opt-ins, mention your list at your next event, and post about it on social media once a week. Small, repeated actions compound into a powerful marketing asset that makes every future event easier to sell.
