Unyson Contact Form- says sent but not receiving

I am using Unyson Contact form. Want the emails sent to my google Apps account, which is hosted through a different website than the one hosting my wordpress website. I tried setting it up that way, and kept getting error codes. So I have the contact form to send to the wordpress host (bluehost), and set up that bluehost email account to forward to my google apps account. Now when I send an email, it says success, but I am not getting the message in either account. I have looked through all of the google apps- contact form advice and I don’t think the issue applies to my situation since I am not using the same domain host for the wordpress website as my google apps account. Any ideas??
