For that, you can try the feature A/B testing. This testing allows you to create two different campaigns and then you can target the audience for those after that you will see the result of which campaign has more opening rate than other. You can make your pages more stylish with these conversion tools.  There are lightbox forms are available which has more conversion rate than regular sign up forms.
PPC advertising is huge in today’s online marketing industry, oftentimes people will click on a particular ad because it told them that they would receive a certain discount or item however once they reach the site, they are forced to search for the item which can be very frustrating. Instapage makes PPC advertising very easy by automatically linking your ads to the designated webpage that you assign during the initial set-up process. You can even set-up special discount codes that will automatically be applied when the potential customer clicks on your link. 

You can also use ClickFunnels as a way to upsell other books that you may have in your catalog. ClickFunnels provides a dedicated upsell page that you can use to integrate special product offers and book deals that may not be available anywhere else. The best part about it all is that all of this is achieved through using your initial landing page. 
Furthermore, you can review their overall ratings, including: overall score (Unbounce: 9.0 vs. Leadpages: 8.5) and user satisfaction (Unbounce: 97% vs. Leadpages: 100%). Analyze their varying features and similarities and see which one outperforms the other. Likewise, think about your company tomorrow; will your company outgrow the app in the next couple of years?
Like LeadPages, but offering you the option of using templates or starting with a blank canvas and building yourself a site from scratch. You can build any kind of marketing page you could desire, you don’t need to worry about the code, and you can even make members-only pages. It’s not cheap, though; nearly $200 monthly for the basic plan, or $1,000 annually for the less limited plan. Still, it’s cheaper than hiring coders and designers.
In addition to providing numerous pre-designed templates, both Leadpages and Unbounce come with easy to use drag-and-drop landing page editors. And each of them supports a wide range of customization options. Their individual layouts, however, are quite different since Leadpages offers a column-based drag-and-drop editor, while Unbounce comes with a pixel-precise one.  
Unbounce also lets you create sticky bars for your site. These bright forms draw attention to the offers and help to get more conversions without paying for more traffic. The editor allows you to add pop-up windows (which are called overlays here) on exit, on arrival, after a delay, on a scroll, or on click. There are plenty of pop-up templates to choose from, and you may also customize them. This feature is not available with Instapage.
