How It Started
Zerorez is a team of cleaning experts who specialize in eco-friendly carpet cleaning. Even though they had a stellar business model, they presented us with a few exciting challenges:
- We were initially only assigned their location in Puget Sound, but they also had other locations across the U.S that required tailor-made content, each with its own offers and promotions.
- Although Zerorez had their own reporting platform, they needed an easier way to consolidate their data to get a better, more comprehensive view of their email marketing program.
With more Zerorez branches being added to the roster, we had some new challenges to solve, including creating relevant campaigns for each audience based on their location and previous services, and addressing some existing dust piles - the San Antonio branch, specifically, had seen disappointing booking rates and revenue.
So, what did we do? Well, we did what we always do - we rolled up our sleeves, grabbed a mop and bucket, and got to work making a clean (and profitable) sweep of things.
By the way, this email marketing case study is no fluke – we’ve got tons of other clients who’ve seen stellar results through CodeCrew.
Polishing Up Zerorez’s Design Approach
A major part of CodeCrew’s success with Zerorez was the fact that we completely overhauled their design strategy to create a squeaky-clean new look.
Here’s how we did it:
- We incorporated more fun and engaging interactive ‘games’ in email layouts that rewarded customers with discounts and cleaning services.
- By transitioning from 600px layouts to 800px layouts, we allowed customers to zoom in on specific details to see the results of Zerorez’s cleaning services up close.
- We used bold typography and crisp, uncluttered layouts to bring the ‘clean’ aspect of Zerorez’s services alive.
While all three branches saw incredible results by partnering with CodeCrew, one branch, in particular, had its very own Cinderella moment…
San Antonio’s Dramatic Transformation
Just like the shy kid showing up to prom in a helicopter, San Antonio’s makeover left everyone speechless. Just look at these email marketing results – all within 3 months:
- 289.5% increase in bookings (from 19 to 74)
- 205.1% increase in booked revenue
- 165.5% increase in click-to-open rate (from 0.87% to 2.31%)
- 56.7% improvement in click rate (from 0.3% to 0.47%)
Bam!
Skyrocketing Engagement Across All Locations
At the same time, all three locations saw a huge uptick in subscriber engagement. Which (all together now) translates to your ability to capture and maintain subscriber attention in an increasingly competitive inbox environment.
Just look at these amazing stats:
-
Puget Sound37.4% increase in unique opens (65,696 to 90,255)
-
Willamette Valley40.9% increase in unique opens (19,689 to 27,742)
-
San Antonio31.6% increase in unique opens (13,018 to 17,129)
Superior Open Rates Across All Branches

-
Willamette Valley60.77% open rate in Q4
-
San Antonio53.57% open rate in Q4 (24% improvement from Q3)
-
Puget Sound54.24% open rate in Q4
That’s not just above average, that’s in a whole new league.
