What do you do when your email marketing is already crushing it?

For most brands, the answer is "don't touch it." For BelliWelli, Future Holidays, and Aimerce, the answer was "make it smarter."

That's exactly what happened when gut-friendly snack brand BelliWelli partnered with email marketing experts Future Holidays and first-party data platform Aimerce. After Future Holidays delivered a hugely successful email overhaul, we saw an opportunity to amplify results even further. By combining Future Holidays' proven automation strategies with Aimerce's advanced tracking technology, we unlocked an additional layer of revenue that was previously invisible.

This is the story of how we took "great" and made it exceptional.

Step 1: Building the Engine (Future Holidays)

First, Future Holidays got the basics dialed in for BelliWelli. They rebuilt their Klaviyo flows from the ground up, turning abandoned carts and back-in-stock lists into powerful, reliable revenue streams. Through strategic segmentation, compelling copy, and optimized automation triggers, Future Holidays created an email marketing engine that consistently converted.

The results were huge, and the foundation was strong. Email marketing became BelliWelli's dominant revenue channel, ultimately driving 50% of their total revenue. The machine was running beautifully.

The "What's Next?" Problem

But we knew there was more money being left on the table. Every day, potential customers visited the BelliWelli site, but thanks to privacy changes and tracking limitations, many remained anonymous "ghosts." Future Holidays' existing automations were working brilliantly for the customers they could see, but how could they reach the ones they couldn't?

This was especially critical for BelliWelli. In the gut-health category, customers need time to research ingredients, read reviews, and build trust before making a purchase. Traditional browser tracking limitations—particularly Safari's 7-day cookie restriction—meant losing visibility on over half of mobile visitors just when they were most likely to convert.

The Answer: A Longer Memory (Enter Aimerce)

The solution wasn't just to get more data, but to expand the timeframe in which we could use it.

Aimerce's Durable ID technology extends the window for recognizing customer activity from just 7 days to up to 1 year. This allowed us to identify users who would normally be lost due to expiring browser cookies and other privacy limitations. Using Aimerce's custom triggers within Klaviyo, Future Holidays could finally target this valuable, previously unreachable audience with their proven automation strategies.

The integration was seamless. Aimerce enriched BelliWelli's first-party data, and Future Holidays deployed their high-performing email flows to this newly visible audience. No complex setup, no disruption to existing campaigns—just smarter targeting.

The Payoff: A 29% Revenue Lift

The result was like adding a turbocharger to an already fast car.

The combined impact of Future Holidays' email expertise and Aimerce's extended tracking delivered a 29% overall Klaviyo revenue lift. But even more impressive was the pure, additive impact from reaching previously invisible customers: Aimerce's technology alone generated a 22% revenue lift from this new strategy, creating a significant and entirely new channel for BelliWelli's growth.

Here's what the partnership unlocked:

• 29% overall Klaviyo revenue increase from enhanced tracking and optimized email marketing
• 22% additional revenue stream specifically from reaching previously invisible customers
• Email marketing driving 50% of total revenue, cementing it as BelliWelli's most powerful channel
• Extended customer engagement window from 7 days to 1 year, dramatically improving abandoned cart recovery

The Lesson: Great Isn't Good Enough

This project proves a simple but powerful truth: a strong foundation is essential, but real growth comes from never being satisfied. By proactively layering cutting-edge technology on top of proven strategies, we're able to find and unlock new pockets of revenue that others miss.

Future Holidays brought the email marketing expertise and proven automation strategies. Aimerce provided the advanced first-party data infrastructure needed to maximize reach and engagement. Together, we created a solution that neither could have achieved alone.

It's how we ensure our clients don't just keep up with the competition; they stay ahead of it.
