Then You Must Customize Your Elements

Some small business owners try to design a Mailing List app solo or get an expensive web designer that promises they can build one.


Others try to find web design companies overseas that appear to offer Mailing List apps for reduced prices or attempt to use open source code.

CASE STUDY: Rbia Shades wins big with POWR

After Rbia launched its website, they were looking for a solution to add new contacts for outreach.


They found POWR while looking for a popup solution on their site and started to see immediate results.

Rbia started to see success with POWR Popup almost immediately, adding over 600 new contacts in the first 90 days.


They then realized that there was a complete suite of other solutions they could use to improve their online experience for site visitors.


Soon, Rbia embedded an Instagram Feed app on their website and noticed site visitors who interacted with the app doubled the time spent on their page while growing their followers to over 11k on Insta at the same time.
