HTML field in E-Mail

Hey,

I am using CF7 along with mc4wp.
To subscibe users to an interest group in Mailchimp, I used the radio buttons of mc4wp.
This is the code for this particular field:

<label>Choose option:</label> 
<input name="mc4wp-INTERESTS[BLAH][]" type="radio" value="123456789" required=""> <span>Option1</span>  
<input name="mc4wp-INTERESTS[BLAH][]" type="radio" value="123456" required=""> <span>Option2</span>  
<input name="mc4wp-INTERESTS[BLAH][]" type="radio" value="123" required="" checked="true"> <span>Option3</span>

Now I would like to add the selected radio button in the e-mail that I receive (because I need to answer accordingly). Is there any possibility to send data from HTML form fields to the mail?

Thank you in advance!

Regards,

Gerardo
