Locating the Guest
Organizers can edit the information of their Guests once they have been registered into the Event.
To set email filters go to your Event > Design > Email.
With the search bar, you can look for an attendee using their name, company, registration type, or registration code. Other contact information will not produce results in this area.
Once you have located the Guest whose information you want to edit, click on their name. Then, their contact card will pop up. Hit edit on the field you wish to change and make sure to click on save when you're done. 
The changes will come into effect immediately.
Feel free to reach out to us at support@boomset.com in case you have questions or need assistance.
