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 Mailing List without a hitch.


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

Save Time With POWR

Plus, updating and customizing a Mailing List app can be challenging, and you may think you have to hire a developer.


Additionally, as your business expands, hackers could see an unsecured Mailing List as a great opportunity to exploit your business and your customers. We consider this and built safeguards!

CASE STUDY: Rbia Shades wins big with POWR

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.
