Sending an email to the test customer

I am totally lost. I have my hosting account through GoDaddy. I thought when I installed ZenCart off of their site it was going to set up everything for me and then all I had to do was set up the pages on how I wanted them to look and to add my products. But now I'm not sure.

I sent an email to the test customer [email protected]. Documentation in the manual says that after the test email is sent, use your mail client (e.g. Thunderbird) to retrieve the test email from the test customer's email account. I don't know what I'm suppose to do here?

Wouldn't my mail client be GoDaddy?
How do I retrieve the test email from the test customer's email account?

Thanks.

I usually register a new e-mail address at yahoo (for example), then create a "test client" with that email address, through the normal zencart customer registration process. This allows me to see what a real customer would see (and have to do). Also, I can place test orders, send test newsletters (etc) using this login.
