If you're needing to get in touch with all clients who are enrolled in your class, Schedulicity makes it easy to do so! Check this out in the Schedulicity dashboard:
Head to the Class Calendar and click on the appropriate session
When the roster opens, you'll see the option to "email clients" near the upper right-hand corner of the screen. Click here!
This won't send the message through Schedulicity, but will instead prompt your default email program to open and create a new message (like Mac Mail, etc). Clients will automatically be entered into the "bcc" field to keep everything nice and private for your clients—they won't see any information or email addresses for other clients enrolled in the class. 👍
Also, keep in mind that if you're sending an email message through an email program such as Outlook, you will need to separate each contact in the bcc field with a semicolon so that it sends to your contact list correctly.
