Contact 7 is the most popular free plugin for creating contact forms on WordPress. If you want to keep track of the forms people submit and see if they turn into leads, especially when using Contact 7 with Google Tag Manager, you need some special code for your database. However, the code that’s available doesn’t give you all the info you need to track Contact Form 7 and its submission values properly.
To address this, we’ve created a complete and working code to help you track Contact 7. With our code and easy-to-follow instructions, you’ll be able to keep tabs on your Contact Form 7 submissions and gather important customer form input data without any hassle.
