Email is a great way to communicate with your client base. Because of this we're working on a bulk email tool for salonMonster which will be coming out soon. In the meantime you can easily export your client emails for you to use in your own email application.
To export your client emails:
Click on "clients" on the left hand menu
Select the three dots on the top right corner of the page
A list of three will appear at the bottom of the page, you will want to select "export emails to CSV"
This will then download the file for you and you can open the document in either pages or Microsoft excel.
