The Problem: Email Marketing Was Not Working Well

A popular Shopify brand in Germany was struggling to get results from their email marketing. They had:
  • Poor email open and click rates
  • Outdated email designs
  • Unorganized and messy contact lists
  • No behavior-based automation flows
Even though they had many customers, their email revenue was low. They knew they needed a better system to reach more people and make more sales through email.

The Solution: Smart Klaviyo Setup and Email Flow Strategy

That’s where Product Siddha came in. The team started with the German store and used Klaviyo, a top tool for email automation for Shopify, to fix and improve everything.
  1. Better Email Designs and List Cleanup Re-designed emails to look more modern and user-friendly Removed inactive or fake emails to improve deliverability Created clear segments based on customer actions like purchase history and product views
  2. Behavior-Based Automation Flows Set up targeted email flows that were based on what users actually did, such as:
    • Welcome series for new customers
    • Abandoned cart reminders
    • Product view follow-ups
    • Win-back emails for old customers
    These flows helped the brand stay connected with shoppers and bring them back to the store at the right time.
  3. Scaling to Other EU Markets After strong results in Germany, Product Siddha rolled out the same setup for three more Shopify stores in:
    • France
    • The Netherlands
    • Spain
    Each store had localized content and email strategies tailored to their market.

The Outcome: Big Growth in Email Revenue

The results were impressive and fast:
  • 55% increase in email-attributed revenue for the German store within 6 months (year-over-year)
  • Product Siddha now manages a €2.5 million email marketing portfolio across 4 countries
  • Higher open rates, click rates, and customer return rates
  • Better customer experience with personalized, timely emails
Product Siddha turned email marketing into one of the brand’s top growth channels.

Conclusion: Smart Email Automation That Grows EU Shopify Brands

By using Klaviyo and focusing on behavior-based flows, Product Siddha helped this Shopify brand grow fast across Europe. With better design, smarter segments, and market-specific strategies, email became a powerful tool again. This case shows how the right MarTech implementation can turn email into a money-making machine.
