Contact form not working

I installed a contact form on a page on my site. That page is here:

http://hbombkaraoke.com/contact/

As a test I tried sending myself an email using the contact form. The message came up that the email was successfully sent; but I never received it in the designated email account. I saw in some old forum posts that there might be a bug that prevents such emails from going to the administrator’s email addy, so I then changed the indicated destination email address to a different one. And it still doesn’t work. (and in neither case did the emails go to my spam filter)

Note: I am not using a plugin, as I’ve been told that plugins can’t be used by people like me who use the WP site to host our blogs (the threads that came up on my search of this topic all seemed to involve plugins). This is the code I have on the page:

[contact-form subject="Message from a blog reader" to="HarvSilk @ aol.com"] [contact-field label="Name" type="name" required="true" /] [contact-field label="Email" type="email" required="true" /] [contact-field label="Website" type="url" /] [contact-field label="Comment" type="textarea" required="true" /] [/contact-form]

(Also note that for purposes of this post I added extra spaces around the “at” sign on the listed email address).

Help! I am very upset that I’ve been telling people that they can email me through my blog, and some might have tried and I’ll never know that those people tried to email me. Also, is there at least somewhere on the dashboard where I can see emails that were sent through my contact page, even though I didn’t receive them?
