Use Eventbrite for taking half marathon registrations, and use Mailchimp for getting runners excited enough to sign up. That is the cleanest setup for most race teams. Eventbrite handles tickets, payments, waivers, caps, and confirmation emails. Mailchimp handles hype, reminders, abandoned interest, sponsor news, and last-minute pushes.
TLDR: Eventbrite is better for the actual race registration page. Mailchimp is better for email campaigns that fill that page. For example, a race director with 2,000 past runners might send three Mailchimp emails and see a 28% open rate, a 4% click rate, and 80 extra registrations through Eventbrite. Use both if you can. Use Eventbrite alone if you are short on time.
Why this choice matters
A half marathon is not just a “buy ticket” event. It has bibs. Shirt sizes. Age groups. Wave starts. Refund rules. Promo codes. Charity spots. Training updates. Weather panic. Very real port-a-potty questions.
So your registration system needs to be sturdy. Your marketing tool needs to be friendly. When those two jobs get mixed up, things get messy fast.
Mailchimp and Eventbrite sound like they might do the same thing. They do not. Mailchimp is an email platform with landing pages and forms. Eventbrite is an event ticketing and registration platform with built-in sales tools.
Think of it this way:
- Eventbrite is the registration desk.
- Mailchimp is the megaphone.
- Your race is the big sweaty party at the finish line.
Eventbrite: best for registration
Eventbrite is built to collect signups. That is its main job. It lets you create ticket types, set prices, collect payments, and cap entries. For a half marathon, that is a big deal.
You can create tickets like:
- Early bird half marathon
- Standard half marathon
- Student entry
- Charity runner entry
- Virtual half marathon
- 5K add-on, if your event has one
You can also ask custom questions. Shirt size? Expected finish time? Emergency contact? Running club? Done.
Eventbrite also sends order confirmations. Runners get a receipt. They get a ticket. They get event details. That reduces the “Did I register?” emails that somehow arrive at 11:47 p.m.
The best part: Eventbrite makes registration feel normal for the runner. They click. They pay. They get proof. Nobody wants a strange form when they are about to spend $75 on pain and a banana.
Eventbrite drawbacks
Eventbrite is not perfect. Honestly, it feels like some settings are hidden two clicks deeper than they should be. Need to edit a question? Fine. Need to check how it appears on mobile? Expect a few extra minutes of sighing.
Fees can also sting. Eventbrite usually charges service and payment processing fees. You can absorb them or pass them to runners. Neither option feels amazing.
Also, the email features are useful, but not as rich as Mailchimp. You can send event updates. You can message attendees. But deep email segmentation is not the strong point.
Mailchimp: best for campaigns
Mailchimp shines before registration happens. It helps you talk to people who might sign up. Past runners. Volunteers. Local fitness groups. Charity supporters. People who clicked last year but never bought. Yes, those people hurt our feelings.
You can create email campaigns like:
- Launch email: “Registration is open!”
- Early bird reminder: “Prices go up Friday.”
- Training email: “12 weeks to race day.”
- Social proof email: “1,000 runners already joined.”
- Last chance email: “Only 150 spots left.”
Mailchimp also helps you segment people. That means you can send different emails to different groups. Past half marathon runners get one message. First-time runners get another. Volunteers get a softer invite. Sponsors get a thank-you plus a promo link.
This matters. A first-time runner may need comfort. A returning runner may need urgency. A speed demon may only care about course certification and medals. Give each group the right nudge.
Mailchimp drawbacks
Mailchimp is not a true race registration tool. You can make landing pages and forms. You can collect interest. You can link to payment tools. But for a half marathon, it gets clunky fast.
Want ticket tiers? Not ideal. Need bib data? Awkward. Need smooth payment confirmation? Use another tool. Need to stop sales at 3,000 runners? Please do not build that from scratch in Mailchimp unless you enjoy stress snacks.
It drives me crazy that people try to force Mailchimp into jobs it was not made to do. It is great at email. Let it be great at email.

Best setup for a half marathon campaign
The smartest plan is simple.
- Create your race registration page in Eventbrite.
- Build your email list in Mailchimp.
- Send runners from Mailchimp emails to the Eventbrite page.
- Track which emails bring signups.
- Repeat what works.
Here is a quick sample plan.
- Week 1: Announce registration. Offer early bird pricing.
- Week 3: Share the medal design. People love shiny things.
- Week 5: Warn that prices rise soon.
- Week 8: Share training tips and local running routes.
- Week 10: Push team entries and charity entries.
- Final week: Send a “last spots” email.
A small race can run this with one person. A bigger race may want a marketing helper. Either way, keep the path clear. Email first. Registration page second. Confirmation third.
When to use Eventbrite alone
Use Eventbrite alone if your race is small or your list is tiny. Maybe this is your first year. Maybe you expect 300 runners. Maybe you just need a clean page and a payment system.
Eventbrite can promote your event through its own search features. It can also send basic emails to attendees. That may be enough.
This setup is fast. You can create a page, add pricing, add questions, and publish. If you already have the race details ready, you might be live in under an hour.
When to add Mailchimp
Add Mailchimp when you have a real audience. If you have 500 or more past runners, use it. If you have sponsor lists, club contacts, and volunteer lists, use it. If registration has slowed down, use it yesterday.
Mailchimp gives you better subject line tests. Better audience groups. Better reports. You can see what people opened and clicked. Then you can adjust.
For example, say your early bird email goes to 4,000 people. It gets a 31% open rate. It gets a 5% click rate. That is 200 people clicking to register. If 35% of those people sign up, that is 70 entries from one email. Not bad for a Tuesday.
Simple tips for better results
- Use one clear button. Say “Register Now.” Not “Learn More.”
- Show the price deadline. Runners move faster when the price jumps soon.
- Add course details. Flat, hilly, scenic, certified. Say it clearly.
- Show the medal. Yes, it works. No, runners are not ashamed.
- Keep forms short. Ask only what you need.
- Send reminders. People forget. A lot.
Final verdict
Eventbrite wins for half marathon registration. It is better for tickets, payments, limits, and runner details. Mailchimp wins for the campaign. It is better for email, audience groups, and repeat promotion.
If you must pick only one, pick Eventbrite. You need a working registration flow first. If you can use both, do it. Mailchimp brings the crowd. Eventbrite signs them up. Then everyone gets to run 13.1 miles and pretend the last hill was “fun.”
