There are times when you may want to schedule emails in advance to be sent at a future time or date, freeing up some time for you to do other tasks. You can set the exact date and time that you would like to send this email out directly inside of the email editor by clicking on the clock icon.
This will allow you to set the date and the specific time that you would like this to be sent to your recipient(s).
You can then view scheduled emails in the "Outgoing - scheduled" tab of the Email Manager - read more about this here.
