Make Your Website Elements Unique

Some may first try to DIY a Mailing List app or 'knows a guy' that can build one in 'no time'.


Others attempt to find open source Mailing List apps, or companies abroad that claim to offer Mailing List apps at rock-bottom prices.

POWR Saves You Valuable Time

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: POWR put Rbia Shades on the success track

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.
