Won’t Send Out Auto-Newsletters

About two months ago I switched Hosts from Bluehost to GoDaddy. I hadn’t realized that my Daily auto-newsletter hasn’t been sending out to the subscribers until recently. So I checked and sure enough the last newsletter was August 11th (I believe). Before anything else I tried sending a preview Newsletter to my email. Didn’t even get that.

I assumed it might have to do with my Host switching. So I duplicated my newsletter and tried again. The preview worked and I got that in my email on the duplicate Newsletter. However, still no auto-newsletter at 10AM everyday for the past two days. Is there something going on that would cause this?
