Planning a virtual webinar or in-person meetup is one thing. Keeping registration under control? Totally different story.
If you’ve ever used HubSpot forms to manage event signups, you’ve probably run into this: everything’s going smoothly… until it’s not. You check the numbers and realize you’ve overbooked the room. No built-in guardrails. No alerts. Just a form that keeps accepting submissions long after your space is full.
event•hapily changes that.
It gives you full control over event and session capacity — natively in HubSpot. No custom code, no awkward cutoffs, no scrambling to email registrants backtracking on your invite.

The Native HubSpot Limitation: No Registration Cap
Out of the box, HubSpot doesn’t offer a way to limit how many people can register for an event. You can create forms. You can send confirmation emails. But when it comes to stopping registrations at a certain number?
There’s nothing built-in.
Which means you risk overselling — or worse, having to manually close down registration at the exact right moment and hope no one clicks the link again.
That’s where event•hapily steps in.

The Fix: Enforce Capacity Automatically with event•hapily
When you use event•hapily to create an event or session in HubSpot, you’ll see a new property called Registrant Limit.
Enter your max number of attendees — and that’s it. Once the limit is hit, the form automatically shuts off. No babysitting. No workflows. Just a clean, capped experience.
Want unlimited registrations? Leave it blank.
Hosting a multi-session event? Each session can have its own limit, so you can allow 300 people in the keynote but only 30 in the breakout room.

When Capacity Is Reached: What Visitors See
You’ve got options — and they’re all built into the HubSpot CMS module.
Option 1: Custom Message
Show a friendly message letting visitors know the event is full — and invite them to future sessions.
Option 2: Waitlist Form
Swap in a waitlist form to collect interest in case seats open up or you decide to expand capacity.
Option 3: Redirect
Send visitors to another page — maybe your full event calendar or a general interest form.
No dev work required. Just choose the fallback experience that works best for your audience.

Manual Overrides (Because Life Happens)
Not everything should be automated — especially when your sales team asks to sneak in a VIP five minutes before the event starts.With event•hapily, you can still manually associate a contact to the event, even after the registrant limit has been reached. You stay in control. The limit enforces itself, but it doesn’t handcuff you.
Why This Actually Matters
Anyone can slap a form on a page. But if you’re managing event strategy in HubSpot — really managing it — you need more than just a signup flow.
Capacity matters because it:
Capacity matters because it:
- Keeps your sessions on track and on-brand
- Improves the attendee experience (no overfilled Zoom rooms or venues)
- Prevents the follow-up nightmare of canceling or turning people away
- Ensures your event team, sales reps, and speakers are all on the same page
And when all of that is managed inside HubSpot — no third-party app, no API sync, no spreadsheet tracking — you can scale event operations confidently.
