[Plugin: Contact Form 7] Checkboxes

I am trying to customise the email the recipient gets from my form. I am unsure how to add the check boxes into the message to say whether they have been ticked or not, can anyone please shed some light on what i would need to do?

Just another thing, i have only recently come across this plugin and have to say it one of the best plug ins i have come across, fantastic! keep up the good work…

Thanks
