This brand had been working with a big agency for the past 18 months.

For over a year, their Klaviyo attribution stayed stuck below 17% no matter what they tried. Then we took over the copy.

In our very first month, we pushed attributed revenue from 15.72% → 29.03% almost doubling the impact of every email and flow.

Here’s the exact “Before vs After” from their Klaviyo dashboard:

Before (Dec 2025):

Total Revenue: £546,889.33
Attributed Revenue: £85,980.07 (only 15.72% of total)

After (Feb 2026):

Total Revenue: £356,020.72
Attributed Revenue: £103,344.07 (now 29.03% of total)

Same flows. Same audience.
Just better copy.

Here’s the sauce we used:

1. Every Product Can Have an Emotional Driver

We’ve seen emotional storytelling work insanely well on products you’d never expect.
Instead of dry features, we connected with the reader on a real emotional level using stories that made them feel seen, understood, and excited.
This single shift alone moved the needle hard.

2. Shifting the Unique Mechanism (and doubling down HARD)

This client sells a highly saturated product the kind you can literally walk into any local store and buy in 10 minutes.
But there was one specific mechanism that actually made their version different.

We didn’t spread the message thin. We doubled down on that one mechanism, built sub-mechanisms and layered benefits around it, and flooded the copy with testimonials + visuals that showed it working (instead of just telling).

“Show don’t tell” isn’t a cliché it’s the reason the new copy converted at almost double the rate.

The agency had been tweaking subject lines and button colors for 18 months.
We changed the story and the proof and the numbers followed.This is why copy will always be the highest-leverage lever in marketing.

You can have perfect flows, perfect timing, and perfect segmentation… but if the message doesn’t hit emotionally and clearly explain why you’re different, the money stays in the inbox.If your attributed revenue is stuck in the 10-17% range and you’re tired of guessing, this is the fix most brands are sleeping on.
