MailChimp List Did Not Capture Number Field

Hi there,

Thanks for making this plugin! I am using Contact Form 7 to collect [name] [phone] [email]. It looks like the plugin sent the info for the name and email, but it did not include the phone number data.

Is this a pro feature, or something I need to modify on my end? Thank you!
