INTRODUCTION

Discover how we rebuilt Gitaar Barbaar’s entire retention system from scratch, warmed up a fresh Klaviyo account, and almost tripled their automated revenue within the first 90 days.

ABOUT THE BRAND

Gitaar Barbaar isn’t just a guitar shop they bring used guitars back to life. Every instrument is restored with care, upgraded where needed, and prepared to play like new. Their audience is full of passionate guitar players looking for quality, character, and good value.

Despite strong organic demand, the brand was barely using email, leaving a lot of revenue and repeat customer potential untapped.

CHALLENGE

Before working with us, Gitaar Barbaar faced several growth blockers:

  • No structured email strategy

  • Almost no automated flows running

  • Email revenue depended on ad-hoc campaigns

  • Low list utilization (existing subscribers weren’t nurtured)

  • No clear post-purchase or repeat purchase logic

  • Email was not a reliable revenue channel

Email existed, but it wasn’t working as a system.

As a result:

  • Revenue was inconsistent

  • Repeat purchases were underleveraged

A lot of high-intent customers went cold after their first order

GOALS

Together with Gitaar Barbaar, we set three clear goals:

  1. Increase attributed email revenue (with a strong focus on automation)

  2. Build a scalable retention system instead of one-off campaigns

  3. Turn email into a predictable, always-on revenue channel

Our Solution

We have implemented:

  • Full Klaviyo migration and warm-up

  • Complete rebuild of all core flows

  • High-intent pop-ups for list growth

  • Strong segmentation and clean flow logic

  • Conversion-focused email design system

We’ve been working together for about a year now and we’re extremely satisfied. While we already had a strong website and solid marketing in place, we noticed that our existing traffic wasn’t being used to its full potential. That’s exactly where these email flows made a huge difference. They set up several one-time flows for us that are still running today and continue to generate strong conversions every month. Think of smarter cart recovery, better follow-ups, and stronger, more valuable content that truly supports our branding. What makes the collaboration even stronger is the speed and quality of their support. Questions and changes are handled quickly, and because they have designers in-house, everything is instantly taken to a much higher level than if you try to do it yourself. The result: more focus for us, time saved, and clearly better performance. They know exactly what they’re doing, and you feel that in everything. Highly recommended.
