Registering multiple people for the same event

Hi everyone,

I'm working through a challenge with our Marketo event registration forms and would appreciate some guidance.

Our business partners want the ability to register clients on their behalf and/or the ability for registrants to add guests, then later pull a full registration list with all registrants.

We’ve run into an issue where a partner enters their own email address but fills out the guest’s name and phone number, causing the form submission to update their existing record instead of creating a new one for the guest.

Here’s an example of what our form would potentially look like:

--

First Name:

Last Name: 

Phone Number:

Email: 

+ Add Guests 

Guest First Name:

Guest Last Name:

Guest Phone Number:

Guest Email Address:

+ Add Another Guest 

--

Currently, I pull registration lists using a Smart List > Filled Out Form filter, but this approach wouldn't capture guest details accurately because the guest fields aren't the primary email address field within the Marketo form.

Does anyone have advice on how to correctly capture guest registrations while ensuring the master registration list remains accurate? Any best practices or alternative solutions would be greatly appreciated!

Thanks in advance!
