starkest on "[Plugin: Contact Form 7] Email Address doesn't Come through"

When I receive a submitted message from my Contact 7 form, the email address doesn't come through on the email. Example:

From: Shari <[your-email]>
Subject: [Newsletter Signup]

State:
Missouri

There should be an email address where is says <[email]> but it never comes through.

Thanks for your help.
