// The agency reality

Senior judgment doesn't scale. Your client roster does.

Every new Klaviyo account you take on needs the same things: a real diagnosis, a prioritized plan, and a report the client actually respects. Today that comes out of your hours, or a senior hire you can't afford yet.

// Problem #1

Reporting eats your margin

Pull Klaviyo exports, build the deck, write the recap. Multiply by every client, every month. The hours you bill for strategy get spent on plumbing, and the report still looks like a KPI dump.

Time drain · ~1 day per account, per month
// Problem #2

Strategy runs on gut feel

"Rework the welcome flow", "test a win-back". Every account manager has ideas, but nobody has quantified what each lever is worth on this client's real volume. So you rank by instinct, and sometimes ship the wrong thing first.

Credibility risk · unquantified recommendations
// Problem #3

Junior output, senior expectations

Clients pay for senior-level direction on every account. But senior strategists are expensive, rare, and don't scale past a handful of brands. The judgment gap shows up in churn conversations.

Scaling wall · headcount grows with accounts
// Problem #4

Dashboards stop at "what happened"

The reporting tools built for Klaviyo agencies consolidate KPIs and export decks. Useful, but 100% descriptive: no audit, no diagnosis, no prioritized fixes, no dollar amounts. You still do the actual thinking by hand.

Tooling gap · rear-view mirror only
// How Retain works

Understand the data. Get the direction.
Deliver the report.

Three pillars, one job: turn raw client data into a defensible direction and an elite client deliverable, without hiring a senior strategist.

// understand

Deeper than a dashboard

12 months of history, cohort retention curves, adaptive RFM, first-to-second purchase analysis, acquisition-source LTV intelligence. Insights a pure-ESP dashboard structurally can't produce.

  • Automatic drop / peak / deliverability detection
  • RFM thresholds that adapt to the brand's consumption pattern
  • CRM independence score + year-over-year comparison
// direct

The fixes, prioritized in dollars

The prescriptive layer nobody else has. Every flow put under the microscope, every opportunity quantified, every recommendation backed by a deterministic engine so the numbers survive client scrutiny.

  • Flow audit: missing flows, starvation, obsolete triggers
  • Revenue opportunities, each quantified in $
  • Lifecycle coverage judged against the brand's real flows
// report

An elite client report in 30 seconds

A narrative business review a senior consultant would write: KPIs, campaigns, flows, audience, action plan. Not a table of numbers. Editable inline, exportable, shareable.

  • Presentation mode: project the deck in the meeting
  • Branded public share link, no client login
  • Strategic audit deck + PDF export
// Beyond dashboards

Every other tool is a rear-view mirror. Retain is the strategist in the passenger seat.

// The flow audit

Every flow. Every gap. Priced.

Deterministic detectors find the problems: missing essential flows, starvation, cascade issues, obsolete triggers. Then a consultant-grade narrative goes on top. Not hallucinated, defensible in front of your client.

Deterministic, then narrative

Engine-backed detectors find the gaps. The AI writes the consultant-grade story around verified numbers. Nothing invented, everything defensible.

Judged against real flows

Lifecycle coverage (welcome, nurture, win-back, replenishment, VIP) is assessed against the brand's actual account, not a generic checklist.

Briefable fix list

Not "consider improving the welcome flow". "Rewrite Email 3 subject + add carousel = +$1,800/month." Ready to hand to whoever ships.

Built so the numbers hold up
in front of your client.

Prescriptive, not descriptive

The only Klaviyo-agency tool that tells you what to do, in dollars. Diagnosis, prioritization, and the deliverable, not just charts.

Deterministic + anti-hallucination

Recommendations are engine-backed. Every opportunity quantified, no hand-waving, no invented figures. That's the credibility moat.

Shopify-crossed depth

Repeat-purchase curves, acquisition-source LTV, replenishment cycles: insights a pure-ESP dashboard structurally can't produce.

An AI that answers, not just summarizes

In-app chat connected to the account's real data. Ask your data, refine reports in natural language, and edit the deliverable without leaving the app.

Retain doesn't replace Klaviyo or your team. It makes both sharper. No production board, no campaign builder, no editorial calendar in this release: Retain is the brain, not the hands. Your existing workflow stays; it just gets a senior strategist behind it.

// FAQ

Frequently asked questions

What does Retain connect to? +

Klaviyo, and optionally Shopify for deeper insight. Klaviyo-only works out of the box; Klaviyo + Shopify is roughly twice as powerful, because Retain can cross email behavior with real order data (repeat purchase, LTV by acquisition source, replenishment cycles).

How is this different from analytics and reporting dashboards? +

Analytics tools describe what happened: consolidated KPIs, one-click reports. Retain does that too, and then goes where they stop: it diagnoses what to fix, prioritizes every opportunity in dollars, and writes the narrative client report a senior consultant would write. Descriptive tools are a rear-view mirror. Retain is the strategist in the passenger seat.

How fast is setup? +

Connect Klaviyo and you get a first quantified diagnosis in about 2 minutes. The full 12-month history syncs in the background. Adding Shopify takes one more click and unlocks the deeper retention analyses.

Will it invent numbers? +

No. Every recommendation runs through a deterministic detection engine with an anti-hallucination layer on top. The detectors find the problems (missing flows, starvation, obsolete triggers); the AI writes the narrative around verified numbers. The figures hold up in front of your client.

Is my data safe? +

Read-only Klaviyo access via official OAuth, revocable in one click. EU hosting (Supabase), row-level security per account, GDPR compliant. Data is never shared across accounts and never resold. Delete everything in one click.

Can my whole team use it? +

Yes. Unlimited seats on every plan. Invite your strategists, your account managers, even a client in read-only if you want.

How does multi-account pricing work? +

Pricing starts at $89/month for the first brand and gets cheaper per brand as you add more: the more accounts you run, the less you pay per account. Every feature is included from brand #1. 14-day free trial, cancel anytime.

Does Retain replace my team or my Klaviyo workflow? +

No. Retain deliberately does not touch execution: no production board, no campaign builder, no editorial calendar. It is the brain, not the hands. Your team keeps shipping in Klaviyo; Retain tells them what to ship, why, and what it is worth.
