CPU is utilizing 100% resource and therefore Queue failed
As stated above, GoDaddy has a lot of resource limitations. You can only send 100 Emails an hour is what I have heard.
That also not at a single time. If it detects you are sending a lot of emails, your process is blocked.
Instead, you can queue up the messages to be sent 1 per 20 seconds or 30 seconds. It will help keep the resources in limits, and your emails are sent to the customers without any problem.
You can use the sleep function for this.
I did the findings and found that I should move to VPS instead of Shared hosting. here are the nice and cheap plans by GoDaddy. https://in.godaddy.com/hosting/vps-hosting
