Remove the Guesswork of Building Your Brand

Website Element Customization is Next

People often ask a 'techie' friend to build a Mailing List for them or hire a 'web guy' that one of their friends referred.


Others look overseas or for low-cost open source alternatives for Mailing List.

Save Time With POWR

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


In a world where scammers infiltrate sites every day, many other Mailing List apps out there aren't built with security in mind, which could expose your customers or worse -- crash your whole site. Not with POWR!

CASE STUDY: Rbia Shades is winning with POWR apps

After much success locally, Rbia needed a way to collect emails effectively on their brand-new website.


Their website provider did not have what they were looking for, so the search was on. After doing their research, they believed POWR was what they needed.

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.
