With Schedulers, you can send a specific block of times that you are available on a certain day.
To do this, you'll need to add your Scheduler to date on your calendar. To do this, go onto the Overview and click Calendar. Click on the date you want to add the Scheduler to and then "Add scheduler"
After the scheduler is added, you will need to either attach to the Lead/Shoot or the Contact.
Once this is done you can click Add Date + Email to send it to your client.
