Getting started with Host
Host is Mobly's registration and pre-event communication layer. When you're running an event that needs formal registration — invitations, RSVPs, branded registration pages, automated email confirmations — Host is where you build and send those.
This article covers the launch flow: how to open Host from a Mobly event and what happens when you do. For the one-time SSO setup, see Connecting to Host.
When to use Host (vs. the classic registration option)
Each Mobly event has two registration paths under its Registration tab. Pick the one that fits the event:
Classic registration (CSV upload)
You already have your attendee list (sales, customer success, or marketing built it). You just want those records loaded into Mobly so the team can check them in at the door. No public registration page, no invitations going out.
Host
You're running formal registration. People discover the event, click an invitation, fill out a registration page, get a confirmation email with a ticket. Host handles the registration page + email automation; Mobly handles the leads + scanning + reporting once they show up.
Most internal-only events use Classic. Most marketing-led events with a public RSVP flow use Host.
Opening Host for an event
In the Hub, open the event you want to set up registration for.
Go to the Registration tab.
Choose Host as the registration method.
Once you click Host, Mobly auto-ingests the event details in the background — name, dates, location, languages — and creates a Host workspace pre-populated with those values. You don't have to re-enter event basics.
A prompt appears asking what additional information you want collected from registrants beyond the basics (first name, last name, email). Add any custom fields your event needs — accommodation preferences, dietary restrictions, workshop choices, plus-one details, consents.
From there, you land in the Host interface and can build out your registration page, email templates, and form details. The event is now wired up.
What Mobly handles vs. what Host handles
Event basics (name, dates, location)
Mobly — you set them in the Hub, Host pulls them in
Registrant data fields, custom form questions
Host — configured per event
Public registration page (the page guests fill out)
Host
Invitation, confirmation, ticket, reminder emails
Host
The actual guest list / leads
Mobly — registrants become leads in Mobly automatically
At-event check-in, badge scanning, on-site capture
Mobly App at the event
Post-event reporting and ROI
Mobly Hub
The mental model: Host runs the pre-event funnel (invite → register → confirm). Mobly runs the at-event and post-event flow (capture → enrich → engage → report).
Guests in Host = Leads in Mobly. You don't need a separate guest list — Mobly handles it. See The Mobly App for capture and The Hub for lead management.
What to set up next
Once you've opened Host for an event, the typical next steps:
Use the AI prompt builder — describe the event in plain language and Host builds the registration page, ticket types, and email templates in one shot. This is the fastest path from zero to a usable starting point
Prepare the event page — refine the registration page guests see when they click your invitation
Create email templates — refine the invitations, confirmations, tickets, and reminders the AI scaffolded
