# Bulk registration for an event Add-on. Please contact your sales representative for additional information. With bulk registration, you can register hundreds or thousands of attendees for an event at one time. Set up your registration form first, then upload a spreadsheet with columns for each registration question on the form (attendee names, email addresses, etc.). To learn more about setting up the registration form, see [Set up the registration form for an event](https://help.webcasts.com/books/event-portal-setup/page/set-up-the-registration-form-for-an-event "Set up the registration form for an event"). **Notes:** - Bulk registration doesn’t send a registration confirmation email.
