The problem
A broad segment is a label. “Mid-size IT teams.” “Public sector buyers.” One campaign goes to the label, and the message has to work for everyone under it. It ends up working well for almost no one.
The label tells you very little. It does not say who is actually in the market this quarter. It does not say what they have already seen from you. It does not say whether the person reading is the one who uses the product or the one who signs for it. Everyone gets the same email, the same ad, the same landing page, and the same result: a little interest from a lot of people who were never going to buy.
The fix sounds simple. Split the segment. Make many small audiences, give each one its own campaign, and let the message fit the people in it.
The catch is the math. Many audiences means many campaigns. Many campaigns means many chances for copy to wander away from claims you can defend. Every extra audience is another place for a headline to promise something the product does not do. So the split only works if something holds the edges. That something is a set of guardrail tiers, and I want them in place before I split anything.
The system
Three parts. A score decides which accounts belong in a small audience. Tiers decide what can change from one audience to the next. Intake decides whether an audience can actually be built and measured.
- ScoreWhich accounts belong
- Copy tiersWhat can change
- IntakeWhat can be built
Signals worth wiring first
A small audience starts as a score on the account, not a label. The score answers four questions. Is this a fit? Is there a reason to call now? Is the account already showing intent? Can a seller act on it?
The weights are a strawman for sales and marketing operations to challenge. They are a model, not a result. Meridian is not a real product. It stands in for the product-specific signals. A contact does not get a separate score. One input asks whether a named buyer at the account can be reached.
Fit is stable. Why now and intent move month to month, so those two decide who gets worked this quarter. Together they separate a large account that is quiet from a smaller one that just got a grant, a new leader, and a trial signup.
- 35FitShould we want this account?
- 35Why nowIs something changing that opens budget or attention?
- 20IntentAre they already moving toward us?
- 10RelationshipCan a seller act on it?
Population is public, so it is the base of Fit. A district with no population of its own uses the sum of the places it covers. The bucket runs from 1 to 5, then multiplies by 3.
| Population | Points |
|---|---|
| Under 50,000 | 3 |
| 50,000 to under 100,000 | 6 |
| 100,000 to under 200,000 | 9 |
| 200,000 to under 500,000 | 12 |
| 500,000 and over | 15 |
| Pillar | Signal | Points | Rule |
|---|---|---|---|
| Fit | Population | 15 | The buckets above |
| Fit | Meridian footprint | 12 | Active 12, lapsed 6, none 0 |
| Fit | Meridian whitespace | 8 | Has a footprint but not the full product 8, partial 4, fully deployed or no footprint 0 |
| Why now | Leadership change | 8 | New leader in the last 12 months 8, 12 to 24 months 4 |
| Why now | Grant award | 8 | $250,000 or more 8, $50,000 or more 5, any award 3 |
| Why now | Bond or referendum | 5 | A public-safety or justice bond passed, inside a 24-month window |
| Why now | Population growth | 4 | The place is over the growth threshold |
| Why now | Crime and caseload | 5 | Caseload up 10% or more year over year |
| Why now | Contract or competitor rebid | 5 | Your contract, or a competitor’s, ends within 18 months |
| Intent | Intent score | 10 | The intent score divided by 10, rounded |
| Intent | Digital engagement | 6 | A Meridian trial or a sales inquiry in the last 90 days |
| Intent | Open pipeline | 4 | Any open opportunity |
| Relationship | Account health | 3 | Green 3, yellow 1, red 0 |
| Relationship | Reference | 2 | Flagged as a reference |
| Relationship | Hosted event | 2 | Has hosted an event |
| Relationship | Reachable contact | 3 | A buyer-role contact with a checked phone or email |
The maximum is 100. Leadership and grants are both 8 on purpose. Both are time-limited reasons to call, and there is not yet enough evidence to say one predicts better than the other.
Why now signals carry a date and an expiry. Points fade in a straight line to zero at expiry, so a change that is almost at the end of its window counts for almost nothing. A flag that has not been checked scores zero. That is missing data, not a penalty. Record how many of the 16 inputs were actually observed. A thin-data account is unknown, not weak.
Build the list from every active account you might market to, with its population and its Meridian footprint. Score Fit from population, footprint, and whitespace. Attach Why now, then intent, then relationship. Sum to a score from 0 to 100. Write the score, the score tier, the lane, and the top three reasons back to the account, so a seller can see why it ranks where it does.
These score tiers are not the Locked, Flexed, and Free tiers later in this guide. Those govern copy. These only rank accounts. The top tier is also capped by how many accounts sellers can actually work. The strawman cap is 500. The cutoffs are placeholders until the score has been run across the whole list and the distribution is visible.
| Score tier | Rule | Treatment |
|---|---|---|
| 1 | 65 or above, capped at the top 500 | Named seller, an account brief, and a sequence |
| 2 | 45 to 64 | Seller-assisted outreach when a trigger fires |
| 3 | 25 to 44 | Marketing-led nurture |
| 4 | Under 25 | Awareness only |
Inside a score tier, sort by Why now plus intent, then by population.
A customer in trouble and a new account with the same score do not need the same call. Each account gets one lane, and the ranking runs inside the lane.
| Lane | Who | What the score is for |
|---|---|---|
| Retain | Red health, or a renewal inside 12 months with yellow or red health | Order the save list |
| Expand | Active Meridian footprint, health green or yellow | Order the expansion list |
| Win back | Lapsed Meridian footprint | Order the reactivation list |
| New logo | No footprint | Order the acquisition list |
Fit and timing together decide the motion. Timing is Why now plus intent.
The signal that fired chooses the opening message. A leadership change gets a reintroduction in the first 90 days. A grant means confirming the award is earmarked for the product before the cycle closes. A bond means getting into the process while the product is being budgeted. Population growth means planning capacity ahead of the workload. A caseload increase means showing how similar organizations handled the higher workload. Digital engagement means following up on a trial or inquiry the account started. A competitor rebid is a displacement play timed to that contract’s end. A joint program, a procurement, or a conference can use the same plays once those signals are being collected. They are not in the score yet.
The weights stay a hypothesis until engagement tests them. Hold out similar accounts that sellers do not work from the list. Compare engagement at the top of the ranking with engagement at the bottom. Reweight toward the signals that predicted engagement. Do not tune the weights to a small sample.
A signal that is almost never filled in does not change the ranking, so do not pretend those points are in play. A health score that covers only a slice of accounts leaves the retain lane blind everywhere else. A caseload signal that covers only large organizations gives smaller ones no credit. A competitor name that is missing leaves the rebid date usable and the “who” unknown. An account with no match in the system of record gets no intent or contract points. Treat that account as unknown.
Four calls are still open, and each belongs with sales and marketing operations. Is 35 / 35 / 20 / 10 right, or should timing outweigh fit for a quarter-long push? Is 500 the real seller capacity, and is that cap total or by region? Should an active footprint raise the score, favoring expansion, or lower it, favoring new logos? Does the retain lane share one ranking with the others, or run as its own list?
The tiers
The tiers are the guardrail. There are three.
- LockedUse the claim as written.
- FlexedAdapt the copy. Do not change the claim.
- FreeLocal work, inside the same audience.
Tier 1 is Locked. Core brand messaging and product positioning, sourced from Product Marketing. Field uses it as is. They can choose which elements to emphasize, but they do not edit it. Product descriptions, competitive positioning, pricing messaging, and compliance or legal language live here.
Tier 2 is Flexed. Campaign-level copy, set by the campaign team with Field input. Headlines, email subject lines, ad copy. Field can adapt it for a region. They can change tone for local business culture, translate copy, or lean on a different content pillar that fits a regional pain point. They cannot introduce a new value proposition, change the target audience, or contradict a product claim.
Tier 3 is Free. Field creates it on their own. Local event promotions, partner co-marketing materials, regional customer spotlights.
Here is what that means for small audiences. Every audience gets the same Locked claims. What changes between audiences is Flexed copy and, where it fits, Free content. The audience itself is not something a region invents mid-flight. The campaign team defines target audience and ICP. Field prioritizes by region.
That split of decision rights matters more than it sounds. Without it, a small audience becomes a place to quietly smuggle in a new claim.
Intake
An audience is not real until marketing operations has built it. Their ask is plain. Requirements come in through an intake form, with the lead time they need, clean audience segmentation criteria, and success metrics defined before launch.
The criteria are the part people skip. “Prospects who showed interest” is not a criterion. A field, a value, and a date range is. If operations cannot build the audience from what you wrote down, the audience does not exist yet, and the campaign will run against a list someone assembled by hand. That list will not be refreshed, and it will not be measurable.
The segment-size floor
There is no floor I can hand you. Every company has to set its own, and it is a Goldilocks problem. Too small, and you cannot tell whether the message worked or you got lucky. Too large, and the audience is a label again. The analytics on campaign performance are how you find the line. An audience under the floor can still be worth serving. It rides inside a neighboring audience until it is large enough to read on its own. It does not get its own campaign, its own copy, or its own report.
When to merge an audience back
Merge two audiences when you cannot tell their results apart. Compare them on the same metric, over the same period, with enough volume to read. If different copy produces the same outcome, the split is costing work and buying nothing. If one outperforms the other, keep them apart. That difference is the reason the audience exists.
Do not merge because the report looks messy. A clean report is often a sign you are looking at an average.
The floor is the other half of the same test. Below it, you cannot compare anything, so an audience that stays under the floor goes back inside a neighbor. The campaign and the Flexed copy for that audience stop. The Locked claims were already shared.
A stale signal is not, by itself, a reason to merge. Rescore the account. Merge only if performance then converges, or the audience falls under the floor and stays there. The call belongs to the person who defined the audience. They are the one who has to retire it.
The numbers
I am not claiming that splitting audiences caused the pipeline-per-program-dollar result at the end of this guide. I am not claiming that it did not. What we did was read campaign performance across smaller segments, looking for the Goldilocks size.
What the operating model has given us is consistency and predictability, from the concept of a campaign through execution and review. As the time to deliver came down, we could run campaigns that were not practical before. When the internal cost of standing a campaign up is nominal, a campaign against a small segment is affordable. If a campaign takes six months to build, it has to aim at a large segment, and the message gets generalized for that broad audience instead of a small one.
I am not mixing this with cost per lead or cost per qualified lead. Those are different metrics. They stay out of this guide.
What you can take with you
Start with what failed. The split fails when it happens before the rules exist, and two things break at once. The copy drifts. Each new audience is another place to say something the product does not do, and Flexed copy gets treated as permission to change the claim. Then the segment is too small to read, so a review cannot tell a drifted claim from a win. You find both in the performance report, which is the expensive time to find them. The other failure is earlier. If a campaign still takes months to build, the small audience never gets made. The message is generalized for a large segment, because that is the only size that can carry the cost.
What I would change is the order. Lock the claims before the first split. Write the audience so operations can build it before the copy is written. Set the floor and the merge rule before launch, so you are not deciding under pressure after a campaign has been running for a month. A stale or missing signal is not a segment. It is an account you have not measured yet.
Here is the checklist.
First, write the audience down in full. Who is in it, what signal puts them there, and what they should see next.
Second, tag every audience’s copy Locked, Flexed, or Free before anything is built. If a piece of copy changes the target audience, it is not Flexed. Send it back to the campaign team.
Third, give operations clean segmentation criteria and success metrics, and respect their lead time.
Fourth, set the size floor from your own campaign performance before launch, not after. Merge two audiences when you cannot tell their results apart, or when one stays under the floor. A stale signal is a reason to rescore, not a reason to merge by itself.
Small audiences are worth the work when the message fits the people in them. They are not worth it if each one is a new place for a claim to drift.
