Emails Not Sending

I have read lots of your posts here regarding this subject but nothing seems to help. I installed “WP Mail SMTP” and when I test it by sending a test email that always comes through quickly. But when I test sending an application it never comes in email. It does appear in the Applications section.

So, I know the external SMTP is working and my host is sending the email and my email is being received and delivered when sent from “WP Mail SMTP” but the Job Manager won’t seem to send.

Any ideas? Thanks in advance!
