## Klaviyo List-Cleaning Case Study

**How a Shopify brand cut Klaviyo costs by 31 % and re-engaged 10 000 dormant shoppers in two weeks**

### About #10

**#10** is a Palo Alto-based ecommerce consultancy. We specialize in Shopify & Shopify Plus development, CRO, and Klaviyo automation for brands around the world, without the overhead of a big downtown office.

### The Problem

| **Pain-point** | **Impact** |
|---|---|
| **50 k+ “active” Klaviyo profiles** | Pushed the merchant into the 50 k billing tier ($545 / mo). |
| **Mixed consent states** | Deliverability risk, low open rates. |
| **Dormant customers** | Dead weight in abandoned-cart and win-back flows. |

### #10’s List-Hygiene Plan

| **Step** | **What we did** | **SEO takeaway** |
|---|---|---|
| **1. Klaviyo list audit** | Exported 34 k-row CSV; mapped consent, engagement, spend. | “Klaviyo list audit for Shopify merchants” |
| **2. Behavioral segmentation** | Built **Engaged**, **Un-Engaged**, **All Active** using opens, clicks, site visits, checkout & order metrics. | “Behavioral segmentation in Klaviyo” |
| **3. Two-email win-back series** | “Still want the perks?” → urgency offer four days later. | “Email win-back campaign for dormant subscribers” |
| **4. Tag-and-suppress workflow** | Tagged non-responders → list suppression → tier drop. | “Reduce Klaviyo cost by suppressing unengaged profiles” |
| **5. Quarterly hygiene SOP** | Delivered repeatable checklist & flow templates. | “Klaviyo list hygiene SOP” |

### Results (14 days)

| **KPI** | **Before** | **After** |
|---|---|---|
| **Active profiles billed** | 50 318 | **33 027** |
| **Engaged profiles** | 20 562 | **30 814** (+10 252) |
| **Monthly Klaviyo fee** | $545 | **$375** (-$170 / mo) |
| **Inbox placement** | 90 % | **94 %** |
| **Spam-complaint rate** | 0.04 % | **0.03 %** |

**Annual savings:** $2 040, money now re-allocated to paid social tests.

### Why It Worked
1. **Data over guesswork** – Segments tied to real behavior, not vanity metrics.
2. **Re-permission before suppression** – 10 k buyers revived rather than deleted.
3. **Tag-first suppression** – Future-proofs against accidental revenue loss.
4. **Lean, global model** – Bay-Area expertise, remote flexibility.

### Should You Use Screenshots?

| **Screenshot** | **Purpose** | **Blur** |
|---|---|---|
| Klaviyo **Account Usage** (before/after) | Visual proof of tier drop. | Hide account ID & dollar amounts. |
| **Engaged Profiles** segment builder | Shows engagement criteria. | Obscure list name & any PII. |
| Billing-tier table | Reinforces $170 / mo savings. | Redact last four digits of card. |

Two or three blurred images add credibility without exposing client data.
