Why would email alerts not work?

I am having an issue with Email Alerts. The Alert shows that it is Active and runs at the designated time; it just isn't sending the email. In the example below I have updated the time to run to 11:00 AM but it was previously 10:00 AM and it ran based on the trigger, no email though. Important to note is the fact that there is no notification in Smartsheets that the trigger ran but when I look at the Workflow it shows that it did. I appreciate any help I can get on this.
