Contact Form Only Sends To 1 Address

I have set up multiple enfold websites. I originally started with my own websites and now have been using the theme for my clients. It appears that the contact forms have only been working when they are set to send to my primary email address. I never noticed this of course because I was receiving the test emails when I’d put them to my own address. But clients have pointed out they aren’t getting their emails. I tested it now with a second email address of mine and I am not getting those emails either.

I am only using a single email address in the email line but unless it’s my primary email it doesn’t seem to be sending. Also, the websites are hosted on the same hosting account. Please help.
