IP not sending automatic emails?

Hi everybody!
I need a system in which invoices sends itself after created, payment confirmation and reminder that sends itself, and recurring invoices that sends itself. For a several days I try to do it in Invoice Plane, but only thing I can do is send every email and reminder manually.
I miss one button to send 60 emails… is there any possibility to have such a button, or a system that sends it fo itself?
