Welcome to the Seller Community, @redford1!
To get a bit more specific here- what kind of email are you wanting to send to your clients? If it's just a generic email with basic information that pertains to all of your clients, you can use our Square Marketing to send them all an email.
Our Square Marketing is a subscription that has a monthly cost associated with it, but you can use it to send an email to every client that has made an appointment with you and has an email address on file.
Let me know if you're looking for something different than this!
