Some tips
In working on a customers Contact Form 7 I came across a way to add a prechecked checkbox. Adding a default:1 will make the first checkbox prechecked. If checkbox two was to be prechecked I would add default:2.
<label> Signup for our newsletter.
[checkbox newsletter use_label_element default:1 "Yes"]
Spam protection.
Honeypot field.
Use a honeypot field to add an invisible field which only autobots will fill out. Autobots are programs that automatically send e-mails to a lot of people. Adding a honeypot field adds the invisible for humans when they look at the form field but bots will fill it in. When a honeypot field is filled in it will not send.
