Your Client's Klaviyo List Hasn't Grown in Six Months. Their Segments Haven't Been Touched in Longer.
Klaviyo list growth and segmentation specialists for agencies. $25/hr. Better lists, better targeting, better results per send.
Every campaign your client sends to "All Subscribers" is a campaign that damages deliverability, drives unsubscribes, and leaves revenue on the table. The popup form hasn't been updated since launch. The segments are stale. Nobody on your team has time to audit the list, clean out the dead weight, and build the segments that actually drive results.
SpecialistHQ gives you Klaviyo segmentation specialists who handle the foundational work that makes everything else perform. Signup forms that grow the list with engaged subscribers. Segments that target the right people at the right time. List hygiene that keeps your client's sender reputation clean.
No long-term contract. Start with 20 hours. Walk away anytime.

Where Bad Segmentation Costs Your Clients Money
The Reality Right Now:
- Your client's last five campaigns went to the entire list. Same message, same offer, same audience. Open rates are declining. Unsubscribes are climbing. Nobody has time to build proper segments.
- The popup form converts at 1.2%. It hasn't been tested or updated since the site launched. Your client's list growth is stagnant and they're blaming your agency.
- 30% of the list hasn't opened an email in six months. Those dead profiles are dragging down deliverability for the engaged subscribers who actually buy.
- Your strategist knows RFM segmentation would improve results. But building those segments in Klaviyo takes hours they don't have between campaign builds and client calls.
- A new client onboards and you discover their Klaviyo account has zero segments, one generic popup, and a list full of purchased emails from three years ago.
What Changes with a Segmentation Specialist:
- Every campaign goes to the right audience. Engaged buyers get different messaging than browsers. VIPs get treated like VIPs. Lapsed customers get win-back offers instead of weekly promos.
- Signup forms are tested and optimized quarterly. Pop-ups, flyouts, and embedded forms capture engaged subscribers who actually buy. Conversion rates improve because someone is paying attention.
- List hygiene runs on a schedule. Dead profiles get suppressed. Invalid emails get cleaned out. Your client's sender reputation stays healthy.
- RFM segments, behavioral segments, and Klaviyo's predictive analytics are set up and maintained. Your strategist uses them to plan campaigns. Your specialist keeps them current.
- New client onboarding includes a full list audit, segment buildout, and form optimization. The foundation is solid before the first campaign goes out.

Why Agencies Trust Us with Their Klaviyo Lists
Segmentation Specialists, Not Generalists
Our specialists build segments and forms in Klaviyo every day. They know the difference between a list that drives revenue and a list that kills deliverability. RFM scoring, behavioral targeting, predictive segments — this is what they do.
Forms That Actually Convert
Generic popups collect generic subscribers. Our specialists build and test forms that match the brand, target the right visitors, and capture subscribers who actually open and buy. Every form gets tracked so your team sees what's working.
List Health Is a Service, Not an Afterthought
Most agencies only clean a list when deliverability crashes. Our specialists run hygiene on a schedule: suppress the unengaged, remove the bounced, and keep your client's sender score healthy before problems start.
Zero Risk to Try
20 hours, no long-term contract. Your team gets a dedicated segmentation specialist with built-in QA. If the segments and forms don't meet your standard, you're out $500. That's it.

Klaviyo List Growth & Segmentation Questions
A bigger list means nothing if half the subscribers never open. Our specialists focus on collecting engaged subscribers through targeted forms and then keeping the list clean with regular hygiene passes. We suppress unengaged profiles, remove invalid emails, and build segments that separate active buyers from deadweight. Your client gets a smaller, healthier list that delivers better results per send.
Every signup form we build includes proper consent language, checkbox opt-ins where required, and links to your client's privacy policy. For EU-based subscribers, we configure double opt-in flows. We tag subscribers by consent source so your agency can audit compliance anytime. Your legal team owns the compliance strategy — we execute the technical setup correctly.
We recommend a monthly segment review cadence. Our specialists check segment sizes, engagement trends, and whether targeting criteria still match the client's current goals. Dynamic segments in Klaviyo update automatically as subscriber behavior changes, but the strategy behind which segments you target needs regular human review. We flag segment drift and suggest adjustments.
Yes. Our specialists set up form variants to test headlines, offers, timing, placement, and design. They track conversion rates by variant and document winners so your strategist can apply the learnings across other client accounts. We also test form triggers — time delay vs scroll depth vs exit intent — to find what converts best for each site.
RFM stands for Recency, Frequency, and Monetary value. It scores customers based on how recently they bought, how often they buy, and how much they spend. Our specialists build RFM segments in Klaviyo so your agency can target high-value repeat buyers differently from one-time purchasers or lapsed customers. Better targeting means higher revenue per send and lower unsubscribe rates.
Yes. Our specialists configure Klaviyo's predictive analytics to build segments based on predicted next order date, expected lifetime value, and churn risk. These segments let your strategist target campaigns to customers most likely to buy soon or most likely to lapse. We set up the segments and document the logic so your team can use them in campaign planning.
