How "Email Newsletter" works for Square Online?

[mardemgofficial]

I set it up and tried and tested it out but nothing happened. No email saying I subscribed nor any notification. When I went to the "Marketing" tab and click "Create Campaign" to see if it integrates sending out emails to my clients for Square Appointments, everything says 0 subscribers. So how can I actually send emails to my clients using Square?

In this case your Square Appointments customers would need to consent for marketing emails so they would have to subscribe. We have a guide on Customer Information collection that may be helpful. Let us know if you have other questions.
