When participants register for your event, they must add an email address to receive all event related communications. Sometimes, participants may accidentally type their email address incorrectly, and therefore not receive the event emails. When this happens, their emails are referred to as 'bounced', meaning emails sent to their address have bounced back to the email system.
When you see bounced email addresses in your 'Manage registrations' screen, you need to get in touch with the participant to get the correct email address, and then transfer their registration to the correct email address.
To check if you have any participants with bounced email addresses, you can click the orange arrows next to 'Email status'.
(You may be able to find the participant's phone number in their registration profile if you have Q+A turned on for your event)
To transfer a participant's registration click the 'manage' button next to the relevant participant, you will open their registration profile, where you will see multiple buttons on the right of the screen. Click the 'transfer registration' button.
Type in the participant's correct email address, as well as their first and last name, then click the 'confirm' button.
Now the participant's registration is linked to an email that will receive event communications.
