You can invite participants to scheduled sessions, or to a campaign of sessions. Start on the Campaign tab and click "Invite participants" in the top right of the screen.
From here, you can enter one or more email addresses along with a custom message to invite the new participants(s). When you are finished with your invite(s), click "Send invite" to finalize the process.
If you'd like to send the invite through a different program of your choosing, you can click "Shareable link" and "Copy" to copy the invite link.
After clicking "Send invite" you receive confirmation that your invites were successfully sent.
