An ABM list is a named list of companies you have chosen to win. Each company is scored against your best clients, and under each one sit the people who can actually sign. You build it in seven steps:
- Pick accounts that look like your past and current clients.
- Score every account and cut the ones below the bar.
- Sort the accounts that pass into tiers, based on how much work each one gets.
- Add the real decision-makers at each account.
- Verify every address and give each account one owner.
- Decide whether intent data earns a place, and set a refresh rhythm.
- Turn each row into a first message.
Before anything goes out, check the list against UK and EU email rules (see the legal section below).
What separates an ABM list from a lead list?
An account list names companies. A contact list names people. An ABM list joins the two: every person sits under a company that passed a score, and every company has one owner on your team. Thousands of VPs with no account logic behind them is a lead list. Calling it ABM does not change that.

Which accounts belong on an ABM list?
I begin with your current and past customers. I always pull a client's past and current customers first, then search for companies that resemble them. If your five best clients are UK civil engineering contractors with 50 to 250 staff, that is your first filter, and a better one than any persona workshop.
Then filter by industry, company size, location and revenue band. For European targets, borrow the EU SME bands so "mid-size" means the same thing in every rep's filters: medium means under 250 staff, plus a turnover or balance sheet ceiling (European Commission).
Existing customers go on only for expansion, upsell or renewal, in their own segment, so a new-prospect message never reaches someone who already pays you.
Keep the pool to one audience. I would rather a team commit one offer to one audience for 12 months than scatter the list across five markets.
How do you score an ABM account?
Score every account on one sheet, then cut. Adjust the points below to your own deals. Without a cutoff, weak accounts drift in because someone liked the logo.
| Criterion | Points | What loses points |
|---|---|---|
| Resembles a past or current client (industry, size, model) | 0 to 3 | No client like it, ever |
| Size band you have delivered to | 0 to 2 | Far bigger or smaller than anyone you have served |
| Location you serve and can contact legally | 0 to 2 | A market where your channel needs consent you do not have |
| A real decision-maker title can be found | 0 to 2 | Nobody with buying power shows up |
| Verified contact data available | 0 to 1 | Only guessed or unverified addresses |
| Only generic titles findable (Manager, Assistant, Associate) | minus 2 | The contact data shows nobody with a specific buying role |
Apply the cutoff like this:
- 7 to 10 points: on the list.
- 5 or 6 points: reserve tab, recheck at the next re-score.
- Under 5 points: rejected.
- 0 on client resemblance: rejected, whatever the total.
A famous brand, a big headcount or a funding headline earns nothing here.
How many accounts should go on an ABM list?
As many as your team can work at the depth each tier promises. Tier 1 is close to what Madison Logic calls 1:1 ABM: the most personalized approach, for high-value accounts with complex buying processes and long deal cycles. Treat the account counts below as a rule of thumb, not an industry standard:
| Tier | Accounts | Research per account | First message |
|---|---|---|---|
| Tier 1 | 10 to 50 | Deep: recent projects, several named people | Written one by one |
| Tier 2 | 50 to 300 | Per segment: shared traits and triggers | Personalized by segment and role |
| Tier 3 | 300 and up | Firmographic fit only | Personalized by niche and role, sent at volume |
Adjust these sizes to your deal value. If you sell huge deals to few buyers, keep tier 1 tiny, because each account gets hours of research. With mid-size deals, most accounts belong in tier 3. A narrow list runs dry before the pipeline fills. To size the pool before you score it, see how to count your target market.
I lean toward the bigger list. Reach only 50 to 100 perfect-fit people a month and timing decides most of them: busy, not ready, not interested. That is a coin flip, not a strategy. You need enough rows for the odds to work: volume negates luck. Whether to work named accounts only or a broad list is a separate decision. The scoring and tiering here work for either.
Which contacts do you add to each account?
My first job here is looking back at a client's closed deals and asking who signed each one. Those names set the titles you search for. For a construction supplier, it could be the procurement and contracts leads at each contractor. For an IT services firm selling to mid-size companies, it could be CTO, Head of IT and Director of IT.
Generic labels come off. I strip Assistant, Manager and Associate from every target list. The only exception is a buying process that truly runs through one of those roles, such as a procurement manager at a contractor.
How many people to add per account:
- Tier 1: 3 to 5 people.
- Tier 2: 2 or 3 people.
- Tier 3: 1 or 2 people.
Pull contacts from a proper data tool rather than a scraper. One UK client, a social media agency, sold into 3 niches, so each niche got its own list from Sales Navigator, Apollo and UpLead, and over 12 months LinkedIn, warm email and cold email booked 714 sales calls. A cheap list from a freelancer costs you later, in weak opens and bounced sends.
How do you verify and own the list before sending?
Run every address through a verifier such as NeverBounce or DeBounce and hold bounces below 0.5%. Bounces get sending domains flagged, and one bad import hurts every account on the list.
Then remove duplicates: people listed under two accounts, existing customers sitting in a new-business segment, and anyone on your opt-out or exclusion list.
Ownership comes last. We give each account one rep and split territory, so two colleagues never write to the same buyer. Write the rules down:
- Each account has one named owner in the CRM.
- Every contact inherits the owner of their account.
- When two reps claim one company, the rep with the live relationship keeps it. Otherwise the account stays with the territory owner.
Before the import, do a full audit of the lead list before a single email is sent.
When should you use intent data, and when should you skip it?
Buying signals only help when enough of your market throws them off. Intent data works by comparison. 6sense's documentation says Bombora flags a surge when an account shows sustained interest in a topic over the past 3 weeks, compared with its usual level over the previous 12 weeks. An account with little activity gives that comparison little to work with.
If you are weighing a platform for this, intent data for a small team covers the options. Take a market of about 2,000 target companies, with intent signals on roughly 10. My team skips intent there and builds an offer the whole list would care about.
The rule: if signals flag enough accounts to fill a week of tier 2 sends, use them to decide what goes out first. If they flag only a handful, ignore them and work the full list.
Lists go stale quickly, because people change jobs and addresses die (how fast B2B data decays). Landbase, a data vendor, estimates that B2B email lists decay about 28% per year. Set a refresh rhythm and keep it:
- Weekly: remove bounces, opt-outs and anyone who replied.
- Monthly: add accounts that newly qualify, and recheck job changes at tier 1 accounts.
- Quarterly: re-score every account and move accounts between tiers based on who replied.
How do you move from ABM list to message?
Every row passed the score for a reason: client resemblance, a size band you serve, a named buyer. That reason becomes the first line.
Order matters. On tier 1 and tier 2 accounts, I want the first touch on LinkedIn. Then comes a warm email: a follow-up to someone who has already seen your name there. Budget 5 or 6 touches across the two channels for each contact. The first message sells the meeting. Talk about the service on the call.
Here is a made-up example of a tier 2 warm email sent after a LinkedIn connection:
Subject: Edge protection on your Leeds school jobs
Hi Sam, thanks for connecting last week. Your team has two school builds running in West Yorkshire. If barriers come up on your next package, would a 15-minute call on Thursday help?

Under 40 words, built on one fact about that account, with one small ask. For the handover between channels, see how to run LinkedIn and email as one outreach sequence.
What makes an ABM list legal in the UK and EU?
In the UK, you do not need consent under the Privacy and Electronic Communications Regulations (PECR) to send B2B email to corporate subscribers. Corporate subscribers are bodies with their own legal status, such as companies and limited liability partnerships. You must not hide who you are, and every email needs a valid address where the business can opt out or unsubscribe (ICO).
The ICO treats sole traders and some partnerships like private individuals, so emailing them needs specific consent or the soft opt-in (an existing customer relationship with a chance to opt out). Flag those rows in the sheet.
UK GDPR still applies, because named contacts are personal data, and the ICO says a contact's objection to direct marketing cannot be refused. That makes the exclusion list from step 5 a legal tool as well as a cleaning step.
My team's campaigns mostly target the USA, the UK and Europe, in English. Accounts in Germany, Austria or the Czech Republic get no cold email from us unless there is a compliant basis; LinkedIn does that work instead, through our LinkedIn outreach service. This is not legal advice.

Questions about ABM lists
What does ABX mean, and does it change the list?
ABX usually means account-based experience: it extends the account focus past the first meeting into sales, onboarding and service. The list stays the same, with the same scored accounts and owners, plus post-sale contacts so renewal and upsell messages reach the right desk.
Is a spreadsheet enough, or do you need an ABM platform?
For most teams starting out, a spreadsheet for scoring plus a CRM for ownership is enough. The brand of CRM matters far less than having one, so no lead dies in somebody's inbox. A dedicated platform can start to pay back once you track intent signals across a large market.
Who should own the ABM list: sales, marketing or operations?
One person should keep the master copy, usually in sales or revenue operations, and run both the first scoring and every quarterly re-score. Reps own their accounts inside it. Marketing feeds in new lookalike accounts and segment data. When two teams each keep their own master, duplicates and double-contacted buyers follow.
What do ABM lists look like in practice?
A safety-equipment maker might list the main contractors on large infrastructure jobs, with site safety and procurement leads under each. A civil engineering consultancy might list the councils and utilities it can serve. Each list covers one audience, with titles matched to it. No amount of clever copy rescues a weak list, so score it before anyone writes a word.
