One of my favorite WordPress plugins is Contact Form 7 – it is a powerful and extremely simple contact form that can be set up in a matter of seconds. Until recently, though, there was no good way to get it to use a custom thank you page – you had to go into the code and hack about, and they were releasing updates on a frequent enough basis that by the time you had your hack in place they were already asking you to upgrade the software.

Anyhow, this has now been fixed and the solution is ever so easy.

At the bottom of the settings page for Contact Form 7 is something called “Additional Settings”

Simply paste the code below into that box, edit the thank you page to reflect the URL that you want, and you are off!

on_sent_ok: "location.replace('http://www.mysite.com/mypage.html');"

Then simply paste the conversion code into your thank you page and you are ready to track contacts / signups on your site!

Note:
I found this solution on the comments at http://www.grapethinking.com/wordpress-contact-form-7-plugin-landing-pag – I will keep my eyes out for any further updates, just wanted to post this clearly as I had to dig around for hours to find it!!
