This is the typical case for Registration with additional information: the buyer pays, the attendee receives an e-mail with a link to fill in their details, and the attendee deletes or loses that e-mail. The registration stays unfinished and the PDF ticket with the QR code is not generated.
Open Orders and find the order by the buyer's name, e-mail, or variable symbol. Check whether the attendee status is not registered — that is the signal the link did not reach the right person.
In Orders open the specific order.
If the wrong e-mail was originally entered for the ticket, click Edit attendee and fix it (available only while the attendee is not yet registered).
Use Resend next to the ticket. The attendee receives a new e-mail with the link to finish registration.
In Tickets (or at the bottom of Orders) there is a Resend the registration link e-mail to all unregistered attendees button. It is useful when:
a few days before the event you spot a gap between sold and registered,
after a bulk ticket purchase (a company buys 50 tickets and the employees register one by one).
Automatic reminders to unregistered attendees are not part of self-service today — bulk resend is a manual step worth scheduling.
On event day (ideally an hour before start), send an E-mail campaign with a reminder and the QR ticket — the attendee then has the ticket in the most recent e-mail, no matter what they did with the previous one.
For Registration with additional information, set a clear message to the buyer that registration is not yet complete — both on the post-purchase screen and in the confirmation e-mail.
After registration is complete, the attendee is edited in the Registration section, not in orders. Order before registration, attendee after registration — the split is intentional.
If the buyer did not enter the attendee e-mails, the links go to the buyer and the buyer forwards them. A bulk Resend to unregistered in this case only re-reaches the buyer, not the end attendees.
