Look up account-based marketing examples and you get a hall of fame. A stunt mailer. A billboard rented outside the target’s office. A bespoke microsite built for one logo everybody recognises. Good stories, all of them. A campaign like that needs a named account manager, a studio on call, and a budget that survives a legal review.
None of that helps if you have eleven target accounts and one marketer. So this piece organises the plays the only way that decides what you can actually run: by how many accounts you are aiming at.
Why Most Account-Based Marketing Examples Are Useless to You
Expensive and strange is what gets a campaign written up in the first place. That selection effect works against you. Copy the tactic without the conditions underneath it and you get the cost without the result.
Two conditions are usually invisible in the write-up. Somebody in sales had already agreed the account was worth that effort, and somebody could name the individual people inside it. Without those two things you are not doing account-based marketing. You are doing demand generation with a shorter list.
Start From the Account Count, Not the Tactic
ITSMA named the three shapes this work takes, and the names stuck. Strategic ABM is one-to-one: a programme built for a single account. ABM Lite is one-to-few, where a small cluster of accounts sharing one problem gets one treatment. Programmatic ABM is one-to-many, personalised at the account level across a much longer list.
Nothing about a longer list makes one tier more advanced than another. Each one is a budget decision. In ITSMA’s 2017 benchmark survey, run with the ABM Leadership Alliance, the median one-to-few programme covered 50 accounts and reported an average programme spend of $3,723 per account. The median one-to-many programme covered 725 accounts. Read those as 2017 survey figures rather than a target. The shape is the useful part: the more accounts one programme covers, the less attention each one can get.
Data table
| Measure | Value |
|---|---|
| Median accounts, one-to-few | 50 |
| Average spend per account, one-to-few | $3,723 |
| Median accounts, one-to-many | 725 |
Pick your tier by asking what one closed deal is worth and how many accounts your salespeople can genuinely work. Not by which tier sounds most advanced.
One-to-One: Ten Accounts and No Automation
At this size nothing is a campaign. The play is research, and the output is a document.
Take one account. Read their last two earnings calls or their last two funding announcements. Find the thing their executives keep repeating, because that is the thing with budget attached. Write six pages about that specific problem, using their words, and put no product pitch in the first four. Then a salesperson sends it to one person, by name, with a sentence saying why they wrote it.
That is the whole play. It does not need a platform. It needs someone willing to spend a couple of days on one company, which is why we find it stops working past about ten accounts.
One-to-Few: One Problem, One Cluster, One Asset
Here the unit is the cluster, not the company. Group accounts by a problem they demonstrably share: the same compliance deadline, the same platform they are migrating off, the same market they just entered.
Build one asset for that problem. A teardown, a calculator, a short assessment. Then run it three ways: a LinkedIn company-list ad set pointed at the cluster, a sequence your sales team sends by hand, and a slot in whatever newsletter those buyers already read. Same asset, three doors.
The discipline is refusing to widen the cluster. The moment you add accounts that do not share the problem, the asset gets vaguer to cover them, and a vague asset converts like advertising.
One-to-Many: The Play That Looks Like Advertising
At several hundred accounts you cannot write anything bespoke, so stop pretending. What you personalise here is the offer, the timing and the exclusion list.
Build the offer for a segment: one asset per industry, or per stack, or per whatever trigger put those accounts on the list. The timing comes from intent signals or a funding event. The exclusion list is the part teams skip and it does the most work. Cut current customers, cut open opportunities your sales team is already working, cut accounts below your minimum deal size. What survives is a list worth paying to reach.
If this sounds like paid media with a tighter audience, that is because it is. The honest test is whether the same list is also being worked by sales. When it is not, you are running demand generation under an ABM label, and the reporting will eventually say so.
The List You Can Actually Run
Account counts are not just strategy. Below a certain size, the channels refuse to serve.
Data table
| Platform requirement | List size |
|---|---|
| Google Customer Match, members, to stay eligible | 100 |
| LinkedIn company list, matched member accounts, to run | 300 |
| LinkedIn company list, companies, recommended | 1,000 |
LinkedIn will not run a company list until it matches 300 member accounts, and it recommends 1,000 or more. Google Ads keeps a Customer Match list eligible only while at least 100 members were added or updated in the last 540 days. Neither platform cares how good your account selection is.
So a fifty-account cluster cannot be a LinkedIn company-list audience on its own. It can be an email sequence, a sales-led motion, a hand-built list of the individual people at those accounts, or a cluster you deliberately merge with two similar clusters to clear the floor. Decide that before you promise anyone a channel plan.
What All Three Plays Share
Strip out the budgets and the same three things are left standing.
Sales agreed the list, in writing, before anything ran. The offer was worth the account’s time on its own, without the meeting request attached. And somebody defined what counts as progress at the account level, which is rarely a lead: a second person from the same company engaging, a reply from someone senior, a meeting the salesperson did not have to chase.
Get those three right and a modest play beats a famous one. Get them wrong and the stunt mailer arrives, gets a laugh, and nothing moves. If you want help sizing which tier your deal value supports, that is the first conversation we have with any B2B lead generation client at COSEOM®.
FAQ
What are the three types of account-based marketing?
One-to-one, one-to-few and one-to-many, named by ITSMA as Strategic ABM, ABM Lite and Programmatic ABM. They differ by how many accounts one programme covers and therefore how much attention each account can receive. The names describe budget shapes, not stages you graduate through.
How many accounts should an ABM programme target?
As many as your sales team can genuinely work, which is usually fewer than marketing wants. In ITSMA’s 2017 benchmark survey the medians were 50 accounts for a one-to-few programme and 725 for one-to-many. Start from sales capacity and deal value, then check the number against the platform minimums before you commit to channels.
Can a small company do account-based marketing?
Yes, and the one-to-one play is the one that scales down best, because it needs research time rather than software. Ten accounts, one well-made document each, sent by a person. What does not scale down is the one-to-many play, which needs enough accounts to clear the ad platforms’ audience floors.
What is the minimum list size for ABM advertising?
On LinkedIn, a company list needs to match 300 member accounts before it can run in an active ad set, and LinkedIn recommends 1,000 or more. A Google Ads Customer Match list needs at least 100 members added or updated within the last 540 days to stay eligible. Below those numbers, plan an email and sales motion instead.
How is ABM different from lead generation?
Lead generation counts people and ABM counts accounts, which changes what progress looks like. A second stakeholder from a target account reading something is real movement in ABM, and invisible in a lead count. The two also fit different deal sizes, which we work through in our comparison of ABM and demand generation.
Do you need ABM software to start?
Not for the one-to-one play, which runs on research time, a document and a salesperson. You need tooling once you are running one-to-many, because somebody has to keep the account list current, push it to the ad platforms and hold the exclusion rules. Buy the platform when the list has outgrown a spreadsheet, not before.
How do you measure an ABM campaign?
At the account level: how many target accounts show any engagement, how many show engagement from more than one person, and how many reach a meeting your sales team did not have to chase. Track those alongside pipeline created from the named list. Lead volume from an account list tells you almost nothing, because the list was small on purpose.
