The challenge
Charlotte Bio wanted to:
Create a revenue spike during a rare flash sale
Engage loyal and first-time customers with a time-sensitive promotion
Make the onsite experience smooth and conversion-focused
The campaign generated six times more customers in six hours than we get on a full regular day, which we really did not expect.

The winning strategy
Charlotte Bio launched a 6-hour flash sale with a 40% discount across all non-discounted products. Using Wisepops, they created two complementary campaigns that worked together to boost visibility and conversions.
1. Launching with targeted timing
The campaign was launched in two phases:
6:00 PM — popup and bar visible to returning customers only
7:00 PM — sale made visible to all website visitors
The offer expired at midnight, creating a tight six-hour window to drive urgency and action.
To build anticipation, Charlotte Bio also sent email announcements at 6:00 PM and followed up with paid ads and social posts at 7:00 PM.
2. Reaching all visitors with two onsite campaigns
Charlotte Bio combined a popup with a website bar to ensure every visitor saw the offer—even those who closed the first message.
Popup (above): Appeared immediately, offering a clickable button that applied the discount automatically at checkout.
Bar (below): Only shown to visitors who didn’t use the popup, with a countdown timer to emphasize urgency.
3. Optimizing for mobile experience
Two separate versions of the popup were used: one for desktop and one for mobile.
The desktop popup generated 137 code applications
The mobile popup outperformed all other campaigns with 700+ applications
4. Reinforcing urgency with a countdown bar
The website bar featured a countdown showing how long the sale would last. This was crucial for shoppers who returned later or hesitated during their first visit.
We added the bar with the countdown to reinforce the sense of urgency for those who did not apply the code in the popup, which was key to success.
