01 · Business Context & Challenge

An active customer database that wasn't being monetized, and a deliverability crisis hiding inside it

Kugellager24 is a premier Swiss supplier of ball bearings and mechanical components, serving engineering enterprises, manufacturing workshops, and retail DIY buyers across Switzerland. While organic search and direct traffic generated steady first orders, their existing customer list was almost entirely dormant.

Email was contributing only 6% of store revenue. Past mass promotional sends had triggered high spam complaints (>0.4%), leading major mailbox providers (Gmail, Swisscom, Outlook) to throttle delivery and threaten domain blacklisting.

Spam Complaint Rate (Critical Risk)

Segmented Lifecycle Flows

The Core Problem: B2B enterprise procurement buyers and single-item B2C retail shoppers were receiving the exact same unsegmented mass emails with unauthenticated domain DNS.

02 · Audit & Technical Diagnostics

What the audit uncovered across data, deliverability & flows

A comprehensive 48-hour diagnostic of the Klaviyo account and Swiss domain infrastructure revealed four critical revenue bottlenecks:

Missing DNS Domain Authentication

Emails were sent through Klaviyo's shared domain pool without dedicated SPF, DKIM, and DMARC alignment, causing corporate B2B mail servers to quarantine messages into spam folders.

Deliverability Flaw

Zero B2B vs B2C Buyer Segmentation

Commercial procurement buyers purchasing bulk industrial bearings received the exact same generic consumer promotions as one-time retail hobbyists, eroding list engagement.

Audience Waste

Disconnected Checkout Recovery Architecture

Abandoned checkout flows were either disabled or using basic single-line shop notifications without dynamic SKU tables, resulting in lost high-intent reorders daily.

Conversion Leak

Lack of Replenishment Triggers

Industrial bearings wear out on predictable maintenance cycles. Kugellager24 had zero automated post-purchase reorder sequences to capture routine replacement purchases.

Retention Loss

03 · Strategy & Implementation

The retention architecture built & executed in 11 weeks

We deployed a structured 11-week turnaround plan focusing on deliverability restoration, custom B2B/B2C lifecycle automation, and high-conversion German-language email design:

1. Deliverability Rescue & Dedicated DNS

Configured dedicated sending domain (SPF, DKIM, DMARC), isolated engaged 30-day cohorts, and suppressed dead contacts, dropping spam complaints to 0.01%.

✓ 100% Primary Inbox Placement

2. B2B Commercial vs B2C Split Logic

Segmented list by order value, commercial domain handles, and product categories, ensuring technical buyers receive catalog specs and volume discount tiers.

✓ 42.4% Avg Open Rate

3. High-Intent Abandoned Recovery Flows

Engineered 3-stage abandoned cart and browse sequences with dynamic product thumbnails, technical specs, stock scarcity reminders, and fast Swiss shipping guarantees.

✓ CHF 2K+/mo Recovered

4. Post-Purchase Reorder & Cross-Sell

Triggered automated lubrication, accessory, and replacement reminders at 45 and 90 days based on industrial bearing consumption rates.

✓ 34% Total Store Revenue Share

05 · Key Strategic Takeaways

What other ecommerce brands can learn from this turnaround

TAKEAWAY 01

Deliverability is Non-Negotiable

Even the best copy and design will fail if domain authentication (SPF, DKIM, DMARC) is broken. Cleaning list hygiene and fixing DNS instantly doubled open rates.

TAKEAWAY 02

B2B & B2C Must Be Separated

Commercial buyers want part numbers, technical specs, and bulk pricing. Retail buyers want fast solutions. Segmenting by buyer intent drove rapid conversion lift.

TAKEAWAY 03

Flows Build Recession-Proof Revenue

By engineering post-purchase replenishment and abandoned recovery flows, 34% of store revenue was generated automatically without spending an extra CHF on ads.
