Recently I wrote a post that compared Optimize Press and Premise, so I'm not going to go over all the features in this post. I just want to show you how to set-up Premise and show you how to create an opt-in page in WordPress.
The only thing you need other than your self hosted WordPress site and the Premise plugin is an email/autoresponder service. Premise offers easy integration with Aweber, Constant Contact, and my favorite Mail Chimp. If you use a different email provider you will need the opt-in form code.
Setting Up Premise
The video below shows you how to setup Premise.
Create an Opt-in Page In WordPress
The video below shows you how to create a simple opt-in page using the default style.
In the video above you saw how to create an opt-in form using the default styles. But you can create your own style by going to Premise –>Add Style. When you add a new style you can change the colors, fonts, some of the backgrounds, and borders for the different parts of the landing page. There is an area for you to add your own css when you are creating a style. That will come in handy when you want to add your own divs, or classes. I found I needed to add my own css to adjust the optin box width, the input width, the label width, and the label positioning.
