CASE STUDY: POWR put Rbia Shades on the success track

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

Rbia grew its contact list by 250% using POWR Popup to collect new email addresses from first-time site visitors.


They also added POWR Social Feed to their site and saw a 200% spike in engagement from their site visitors. They also saw a big jump in social media followers and now have over 11K followers on Instagram.
