OPPORTUNITY / CHALLENGE
What specific goals or objectives did you hire Inboxio to accomplish?
Our email marketing was underperforming despite having a strong customer base. We hired Inboxio to rebuild our entire email strategy from the ground up - specifically to increase revenue from email, build automated flows that educate customers about our products and drive repurchases, reduce our dependence on paid ads by monetizing our existing list, and create a consistent brand experience across all email touchpoints.

Describe the scope of work in detail. Please include a summary of key deliverables.
Inboxio completely restructured our email marketing. They started with a thorough audit of our Klaviyo account, identified major gaps in our automation, and built a new strategy from scratch. Key deliverables included: full welcome series redesign focused on product education and first-purchase conversion, browse and cart abandonment sequences, post-purchase flows with replenishment reminders and cross-sell recommendations, win-back campaigns for lapsed customers, branded email templates that match our visual identity, optimized sign-up forms with improved conversion rates, ongoing campaign management with seasonal planning, and detailed weekly reports showing revenue impact of every email sent.
RESULTS & FEEDBACK
What were the measurable outcomes from the project that demonstrate progress or success?
The transformation was significant. Within 90 days, email revenue grew from around 10% to consistently over 28% of total store revenue. Our welcome flow alone now converts at a much higher rate than before. Replenishment reminders brought back customers who would have otherwise been lost. Customer lifetime value increased measurably, and our repeat purchase rate nearly doubled. Most importantly, we finally have an email channel that generates predictable, recurring revenue independent of ad spend.
Describe their project management. Did they deliver items on time? How did they respond to your needs?
Flawless execution. They provided a detailed timeline during onboarding and stuck to it consistently. Every flow, every campaign, every template was delivered on schedule. What stood out was their responsiveness — whenever we had feedback or last-minute changes, they turned things around quickly without compromising quality. They also proactively flagged opportunities we hadn't considered, which showed they were genuinely invested in our success.

Email or Messaging App
What did you find most impressive or unique about this company?
Their ability to understand our customers on a deep level stands out. They took the time to learn how our audience thinks, what motivates their purchasing decisions, and how product education plays into the buying cycle. The emails they created didn't feel like marketing - they felt like a natural extension of our brand. That level of strategic thinking is rare, especially at their price point.
Are there any areas for improvement or something Inboxio could have done differently?
We genuinely struggled to find anything to criticize. The quality of work, the communication, and the results all exceeded what we expected. If we had to mention something, it would be that we wish we had engaged them sooner — the revenue we were missing out on before was substantial.
