If you click on a particular ‘Shortlist’ from within your account (click on ‘Shortlists’ from your left hand menu to access your current shortlists), you will see the option to ‘Send group email’ when you click on 'Actions', which pops up. This will allow you to send everyone on your shortlist a message with just a few clicks. Once you click to send your message, you will also receive a copy of the email to the registered email address you are signed in with.
For represented performers, the message will go to their agents. Fo those self-represented, it will be emailed to the performer directly.
Please note that the option ‘Share via email’ (which you’ll see as an option at the top of the page) is a different feature, this is how you send the actual shortlist details to a third party email, such as a Director or Producer.
