Use attendee email restrictions when only certain people should be able to see or buy a specific ticket, add-on, or donation. This gives you item-level control without restricting registration for the whole event.
You can restrict by full email address or by domain-style endings. Add one entry per line, such as [email protected] or @example.com. HeySummit checks whether the attendee email ends with one of the values you enter.
To set this up, go to Revenue, open the ticket, add-on, or donation you want to manage, and find the Attendee Email Restrictions section. Use Only Allow Emails That Include for an allow list, Reject Emails That Include for a block list, and Message to Show When Email Address Isn't Allowed for the customer-facing error message.
If both allow and reject rules are set, an attendee must pass both checks. For example, their email must match the allow list and must not match the reject list.
If HeySummit already knows the attendee's email address, restricted items are filtered from ticket, add-on, donation, and logged-in purchase views. If the attendee has not entered an email yet, items may still appear at first, but HeySummit validates the cart before checkout can be completed and asks the attendee to update their selection if their email is not allowed.
These controls are part of Advanced Ticketing. If the fields are disabled or unavailable, your plan may not include advanced ticketing controls. For more on ticket access controls, see Advanced ticketing and ticket permissions.
