This Tutorial Shows how to use GroovePages to Build your Optin Forms and Send the Data to GrooveMail.
Using the default GrooveMail embed codes allows you to add a GrooveMail form to your GroovePages Websites or Funnels.
There's also no direct integration, although one is coming in the near future so this method will most likely not be necessary then.
Using this method, you can build your form inside of GroovePages using the default elements and editor, so you can style them any way you'd like (to better match your Website or Funnel appearance), and then pass that data to GrooveMail, including custom fields.
If you don't already have a text editor for editing code, you can download a free editor for Windows (Notepad ++) or Mac or Windows (Atom).
This tutorial also shows you how to change an input field to a dropdown field, so you can have predetermined answers instead of allowing free typing (which might result in a wide range of answers).
This is great for segmenting your audience for better targeting.
Below is the code you can use to replace your standard <input> code, just replace the information in your block code.
