‘From’ email is not sent in notification email

I have tried the WP HTML Mail – Email Designer plugin and it works (mostly) fine and is easy to use. I have a contact form on my site created using contact form 7. It collects the standard info, including the required email address of the person trying to contact me. However, your plugin correctly styles the email but does not include the sender email within the notification email sent to me. Is this by design? Or do I need to change the tag location in Contact form 7?

Cheers ??
