A Clean List Is a Profitable List
List size is a vanity metric. List quality is a revenue metric. We clean, segment, and manage your Klaviyo lists so every subscriber is there because they want to be — and your sends reach the people who actually buy.
What's Included
Our Process
List Health Assessment
We analyze your entire subscriber base — engagement rates, bounce rates, spam complaints, and subscriber quality. This reveals how healthy your list really is beneath the surface.
Cleanup & Hygiene
We remove invalid emails, duplicates, hard bounces, and long-term unengaged subscribers. Painful in the short term, transformative for deliverability and engagement rates.
Segmentation Architecture
We build a segmentation framework based on purchase behavior, engagement level, customer lifetime value, and product affinity. These segments power every campaign and flow.
Compliance & Governance
We audit your opt-in processes, unsubscribe mechanisms, and data handling for GDPR, CAN-SPAM, and CCPA compliance. Protecting your brand means respecting your subscribers.
Ongoing Management
Lists degrade over time. We implement automated hygiene processes — sunset flows, re-engagement campaigns, and regular cleanups — to keep your list healthy permanently.

We review your entire opt-in flow — signup forms, consent language, data storage, and unsubscribe processes — to ensure compliance. We also help implement proper consent tracking in Klaviyo for EU subscribers.
We recommend a thorough cleanup quarterly and automated hygiene processes running continuously. Sunset flows that suppress unengaged subscribers after 60-90 days of inactivity keep your list clean between manual cleanups.
Yes. List growth and list quality are not mutually exclusive. We help you build high-converting signup forms with proper expectations, double opt-in where appropriate, and immediate engagement sequences that set the right tone from the first email.
