Then You Must Customize Your Elements

Some small business owners try to build a Newsletter Sign Up Popup app by themselves or get an expensive web designer that claims they can build one.


Others try to enlist web design companies overseas that claim to offer Newsletter Sign Up Popup apps for reduced prices or attempt to use open source code.

Also, customizing these apps usually requires coding experience or another designer to help -- costing even more resources.

CASE STUDY: Rbia Shades is winning with POWR apps

A few months after Rbia Shades launched at local fairs and craft shows, they were looking for a way to sell online.


They wanted to visually appeal to site visitors and demonstrate the quality of their product and lightweight, ergonomic designs.


Their web host did not provide an adequate solution for this, and after some research, decided to give POWR a try.

Rbia grew its contact list by 250% using POWR Popup to collect new email addresses from first-time site visitors.


They also added POWR Social Feed to their site and saw a 200% spike in engagement from their site visitors. They also saw a big jump in social media followers and now have over 11K followers on Instagram.
