Hello,
Thanks for reaching out! There is not currently any built-in functionality to send out emails to attendees. However, you can export the attendees list and then import the email addresses to a third-party email platform.
If this is a feature that you would like to see added in the future, please do let us know over in our Feature Ideas Forum! This is what we use to gauge user interest in new features and help guide future development efforts.
I’m sorry I don’t have a more straight-forward solution for you here, but please let me know if you have any questions.
Thanks,
Jennifer
