Hi Rhys, thanks for the advice. After further investigation, I discovered that the emails were in fact being sent, however they are for some reason being flagged and blocked by major servers like gmail and hotmail. See message below:
220.127.116.11 failed after I sent the message.

This is a brand new address that I just created yesterday and the only mail that it has sent has been to myself. I have my web host working on it.
I'm interested in the alternative your proposed though, I have the WP Mail SMTP plugin installed and activated, maybe I'll test it with a gmail address instead of the one that is bouncing back. Is there anything special that I need to configure in the WP Email Capture plugin in order to use it with WP Mail SMTP?
Thanks for you help!
