Important Note
We highly recommend to turn on this feature as having a unique email address is required to access the event. The email address is the attendee's identifier. If attendees are sharing an email address, they will have issues as they are sharing a profile. They may have incorrect names when they check in and claim their badge and when they log in to the app.
Requiring ticket holders to have a unique email address can limit attendees to one ticket per event. This is ideal if an event has limited capacity. Another benefit is that you can ensure that attendees cannot accidentally buy multiple tickets under the same email address, making your analytics accurate without duplicates.
Note: For recurring events, this feature will allow them to buy 1 ticket per event, not per day. We are working on improving this feature. Stay tuned!
Restrict Attendees to Register Only Once With the Same Email Address
Go to Registration > Order Form in your admin console
Click Settings
Turn on the toggle for Each Ticket Holder Must Have a Unique Email Address
Note: When you use this feature and do not collect both ticket buyer and ticket holder information, registrants will be restricted to buy 1 ticket per order as the buyer will also be the ticket holder.
When a ticket is already selected, the other ticket types will be grayed out.
What happens when there's an attempt to register again?
Since they already have a ticket for the event, they can no longer get another ticket under the same email address.
If there is an attempt to register them again, whether it be through the registration page or through the admin console or staff portal, the registration wouldn't go through. They will get this error message:
Scenario | Error Message |
Single Ticket in an Order |  |
Multiple Tickets in an Order |  |
Import Through CSV
It wouldn't allow you to upload the attendees in the CSV if at least 1 attendee already exists. |  |
Import Through HubSpot, Salesforce or Marketo integration | There is no error message, and it may even give you a success message in the CRM, but the order will not be created in Accelevents. |
Is there a scenario where it would create duplicate attendees?
🔴 If the registration is coming from other integrations (e.g., Zapier, Sched, EdgeReg etc.), it can create a duplicate if there's already an existing registration. We are improving this feature, stay tuned for updates.
What Happens When Use This Feature and I Disable the Toggle to Collect Both Ticket Buyer and Ticket Holder Information?
Since you're not collecting the information for both, the assumption is the ticket buyer and the ticket holder are the same person. Therefore, they will only be allowed to buy 1 ticket per order for the unique email feature to work. Other ticket types will be grayed out after a ticket is selected in the registration.
Frequently Asked Questions
Can the ticket buyer and ticket holder have the same email address?
Yes, as long as the email address is used for one ticket holder.
Can the ticket buyer use their email address multiple times as a buyer?
Yes, an email address can be used multiple times as a ticket buyer as long as the toggle for Collect both ticket buyer and ticket holder information is enabled.
What happens if someone buys a ticket and an add-on?
It will allow them to buy a ticket and an add-on with the same email address, given that this is their first and only ticket to the event.
What happens if someone buys different ticket types?
They won't be able to buy multiple tickets under 1 email address. An email address can only be used for one ticket holder, so different email addresses must be used even for different ticket types.
What if the buyer doesn't know the email addresses of the other ticket holders?
The ticket buyer can complete the purchase without the email addresses of the other ticket holders. You can disable the toggle to make those fields required for ticket holders.
The rule will still apply when the order is updated with the email addresses that only 1 email can be registered per ticket.
Can they go into their account and change the holder's email address to be the same?
They can go to their account, but it will not push through if they attempt to change it.
Will this also work in the admin console? Staff portal? Admin App?
Yes, the platform recognizes that the email address has been used and that there is an existing ticket for the event.
Will this feature work for single-ticket orders and multiple-ticket orders?
Yes
After canceling a ticket, can I place a new order for the same attendee?
Yes, canceling the ticket frees up the email address from its association with the ticket.
