Brand Intro

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.

The designs we made

These are some of the designs we crafted.

The challenge

When we started:

Attributed email revenue was declining, down 8% versus the previous period
Email sat at 23% of attributed revenue, with no structure in place to push it further
One-of-a-kind inventory made standard ecommerce email tactics useless you can't send a “back in stock” email for a one-of-a-kind guitar…
A high-consideration audience that needs nurturing over weeks, not just a coupon on day one
Growing send volume with no engagement guardrails is the fastest route to deliverability problems

We have implemented:

All core flows built out in the account: Welcome, Abandoned Cart, Abandoned Checkout, Browse Abandonment, Post-Purchase, and Winback doing the heavy lifting, continuously optimized.
Optimized pop-ups feeding the list and the Welcome Flow behind it
Strict segmentation and list hygiene: sending to engaged subscribers instead of blasting the full list
Monthly reviews against Klaviyo's peer benchmarks to find the next optimization

The result

Email's share of attributed revenue grew from 23% to 57% 2.5× in one year
Flow click rate 2.6× the Klaviyo peer median; campaign click rate 5.5× peers
Deliverability score up 12 points to 80 (“Good”) while send volume grew

The results we got

In one year, email went from a shrinking channel to the largest attributed revenue driver in the account with engagement running far ahead of Klaviyo's own peer benchmarks and deliverability improving as volume grew.

23% → 57% email's share of attributed revenue a 2.5× in twelve months
2.6× peers flow click rate; campaign click rate 5.5× peers (Klaviyo benchmarks, rated "Excellent")
65.5% open / 12.3% click on the Browse Abandonment flow both "Excellent"
~2× peer median revenue per recipient, on flows and campaigns alike
Deliverability up 12 points to 80 ("Good") while send volume scaled

* No email campaigns were sent during this period all revenue was generated by flows alone

Before and after

Before

Email's share of attributed revenue: 23% and shrinking (-8% vs. the previous period)
No engagement guardrails while send volume grew
Standard ecommerce tactics useless for one-of-a-kind inventory
High-consideration buyers left unnurtured

After

Email's share of attributed revenue: 57% the largest channel in the account
Engagement 2× to 6× the Klaviyo peer median, rated "Excellent"
Revenue per recipient ~2× peers, on flows and campaigns alike
Deliverability up 12 points to 80 ("Good") while volume scaled

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.
