Case Study 01
Apparel · DTC · Klaviyo
Act I — The Problem

2.1% open rate.

340,000 dead subscribers.

A DTC apparel brand had spent three years building their list through paid acquisition. By the time they came to us, 91% of it hadn't opened an email in six months. Their ESP was flagging them as a spam risk. Deliverability was collapsing. Every send was making it worse.

We noticed you've been quiet. No pressure.
Preview: This isn't a sale. Just checking in.
Hey —
We noticed you haven't opened one of our emails in a while. That's okay. Inboxes get busy. Algorithms get weird. Life happens.

We're not here to flood you. We just wanted to check: still interested in what we're building? One click tells us everything.
Yes, keep me in →
No click in 7 days = we'll remove you. No hard feelings.
Act III — The Result
Open Rate
2.1%2.1%

From spam folder to inbox. Re-engagement sequence rebuilt send reputation in 6 weeks.

Revenue Recovered
$0$0K

First 90 days from the re-engaged segment alone. No new paid acquisition.

List Cleaned To
340K89K

Painful cut. But the 89K that remained converted at 7× the rate of the full list.

The second client had the opposite problem. Not a dead list — a leaking funnel.

Case Study 02
Home Goods · Mid-Market · Mailchimp → Klaviyo
Act I — The Problem

67% of carts abandoned.

0 recovery emails sent.

A home goods retailer with $4M in annual revenue had Klaviyo installed for 18 months. Zero automations live. Their ecommerce director had been "meaning to set up flows." Every day, 67% of carts walked out the door with nothing chasing them.

Case Study 03
Legacy Retail · Enterprise · 400K List
Act I — The Problem

400,000 subscribers.

2 sends per month.

A legacy retail brand with 23 years of customer data had built one of the most valuable email lists in their category. Their marketing VP knew it was an untapped goldmine. But they were sending two newsletters a month — no segmentation, no automations, no strategy. Revenue per send: $2.10.
