With the Email Manager, you can send yourself a test email, before Emails are activated.
This will allow you to get a preview of the Email which will be sent to your Participants, directly from your mailbox.
1) Go to Studio → Event → Communications → Emails
2) Select the Email that you want to send and then click on the Send Test Email button.
3) Type in the name of the Participant (you!) in the search field and click Send Test Email. Please ensure that you have already added yourself as an Attendee before sending the email.
