Now You Have To Make Your Elements Unique

Some may think only a 'techie' in the office or a self-proclaimed 'expert' on Facebook can expand a newsletter sign up without a hitch.


Others look for low priced alternative newsletter sign up apps from overseas or open source newsletter sign up apps that claim to have what they're looking for.

Also, customizing and updating a newsletter sign up app involves even more time, and is likely to cause new bugs.


As your company continues to progress, you're likely to face security issues, as hackers may attempt to manipulate vulnerabilities in the newsletter sign up app. POWR has you covered!

CASE STUDY: Rbia Shades completely transformed their online experience

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.

In just a few short months of installing a POWR Popup app, Rbia earned over 600 new contacts – a 250% growth.


Next, they used a Social Feed app and quickly noticed a leap in new followers on Instagram and 200% more engagement on their site.


Last came the Media Slider. A beautiful way to show off their products and accessories to every site visitor the moment they land on their site.
