70% Open Rates: 5 Ways We Make Newsletters Deliver Outstanding Results For Businesses As An Email Marketing Agency
Industry: Personal Care
Platform: Shopify + Klaviyo
Focus: Welcome Flow Optimization, ZPD Collection, Conversion Copywriting
The Challenge
Most DTC brands believe their automations are “set and forget.”
But when we audited this personal-care brand’s flows, we found something familiar:
the basics were there, but the messaging, timing, and audience logic were quietly leaking revenue.
The welcome flow was underperforming.
Signup rate: 8%.
Flow revenue contribution: under 10% of total retention sales.
The brand’s goal: turn this first interaction into a real growth engine.
The Breakthrough
Step 1: Build From Data, Not Assumptions
We introduced Zero-Party Data (ZPD) collection — a short, quiz-style popup that asked visitors why they were shopping.
This gave us real insight into purchase motivation, which fed directly into the flow’s segmentation logic.
AI tools like Klaviyo’s predictive analytics helped map responses to buying intent, so every subscriber got a message that felt personally written.
Step 2: Rewrite for Conversion Psychology
We rebuilt the flow copy and graphics to align with brand voice and conversion triggers.
The new flow had:
Emotionally intelligent headlines that mirrored user intent.
Mobile-first visuals optimised for thumb-scrolling.
A clear value story instead of “sign up for 10% off.”
Step 3: Use Micro-Incentives, Not Blanket Discounts
Instead of generic promo codes, we layered contextual incentives— like early access to new launches or reward points for survey answers.
These were powered by AI-assisted segmentation models, which predicted who would buy without a discount.
The Results (in just 2 weeks)
From £2,880 to £8,000+ in revenuefrom this single automation.
Sign-up rate increased from 8% to 15%.
Welcome flow alone drove 21% of monthly retention revenue.
Total retention revenue hit £38,000+ (30% of total).
Those numbers mirror what top Shopify retention teams achieve when they combine data and creativity — not templates.
Why It Worked
Personalised entry point: ZPD made customers feel seen from the first click.
On-brand, AI-supported storytelling: We let machine learning inform timing and targeting but kept human creative in control.
Flow logic re-engineered for behavior: Follow-ups changed based on quiz results and interaction depth.
Minimal discounts, maximum clarity: No margin loss, yet double signups.
It’s the same principle driving results for other brands we’ve worked with — from Jubilee Scents to Vikings Nutrition.
