Marketing · Marketo data quality for AIMarketo scores leads. On data nobody checked.
Marketo sits at the top of the funnel, so any AI that scores leads, predicts pipeline or attributes revenue depends on its person and program data. Years of form fills, list uploads and a two-way CRM sync leave duplicates, dead addresses and conflicting program history. We compare Marketo exports with the CRM and finance to show what a model would learn.
Starts with a 30-minute call. Commits you to nothing. Then exports only: no login, no connected app, nothing installed.
Source of truth
What Marketo gets right.
Every system is built to be right about something. Knowing what Marketo owns, and what it doesn’t, is where a cross-system check starts, and where the Truth Score™ (a score out of 100 for how far your data can be trusted) begins to take shape.
- 01
Marketing engagement
Email, web and event activity by person.
- 02
Program membership
Which campaigns and programs each person touched, and their status.
- 03
Lead score
Behavioural and demographic scoring, as configured.
Pipeline or revenue. Opportunities and closed deals live in the CRM, and revenue in finance; attribution in Marketo only holds if all three agree.
Inside the system
Common Marketo data problems for AI.
What goes wrong inside Marketo itself, with the objects and fields where it shows. Each one is checkable from an export.
- 01
Duplicates email dedupe misses
Marketo dedupes on email, but blanks and variant addresses let the same person exist several times, inflating engagement.
Email AddressLead IDOriginal Source Type - 02
CRM sync that disagrees
Lead and contact fields diverge, sync errors stall records and the two systems quietly disagree about the same person.
SFDC TypeSFDC Idsync status - 03
Dead addresses left active
Hard-bounced and invalid addresses still count in engagement signals and scoring.

Program and channel drift
Naming, program types and channels differ by team, so the same touch is categorised three ways.

Between systems
Marketo looks clean on its own. The gaps are next door.
The problems that sink AI sit between Marketo and the systems beside it: the same customer, person or transaction recorded differently in each. These are the gaps to test for each pairing.

Marketo ↔ CRM
- The same person as a Lead and a Contact
- Scored leads never worked in the CRM
- Fields that differ after sync
What to export
What we need from you, in plain English.
Smart lists and program membership export to CSV from Marketo; larger databases can come in batches. We send the field list first. We need no Marketo user and install nothing.
- Exports only, no access to your systems
- NDA and data processing agreement first
- The full list of sub-processors comes with our data processing agreement, before any data moves
- Raw exports deleted after the engagement; we keep quality metrics, not your records
AI that depends on it
AI use cases that lean on Marketo.
If one of these is in a proposal or your plan, Marketo is one of the systems we compare. Each page sets out what the use case needs and where it breaks.
- Revenue Lead scoring Marketo’s own score, or any model replacing it, learns from engagement and outcomes that must match the CRM.
- Revenue Personalisation Personalised nurture relies on one person, one record, with consent recorded once.
- Revenue Revenue forecasting Pipeline sourced from marketing only forecasts well when program history ties to opportunities.
How a Truth Score Read tests Marketo
From your exports to a signed verdict.
Within 5 working days of complete exports. A fixed fee, agreed before we start, that never moves with the verdict.
- 01
Export Marketo, and one system beside it
The Marketo exports listed above, plus at least one neighbour, such as CRM. Under NDA, using the field list we send.
- 02
Match across systems
Our engine matches each person and its related records across the exports by ID, name, email and domain, including the ones spelt differently in each system.
- 03
Check by hand, then score
Every red flag is checked by hand against sample records before sign-off. Then the Truth Score: each pillar shows what was measured and what wasn’t, and pillars with too little signal are marked, never guessed.
- 04
Get the verdict in writing
A signed memo: the red flags between Marketo and the other systems, a Leverability read on the AI you’re considering (which AI ideas you can use now, after fixes, or not at all), a verdict (sign, fix first or walk away) and a short fix list your own team can work from.
What you get back
See what comes back: a real sample memo.
One fictional B2B software company, Example Co: 72,837 records in 7 exports from its CRM, finance and HR systems, run through the same engine and the same checks as a paid Truth Score Read. Each system passes its own checks. Matched across systems, only 13% of deals tie to an invoice.
Questions
Marketo and AI, answered plainly.
Anything else, ask on the 30-minute call. It commits you to nothing.
Book the callCan you assess Marketo from exports?
Yes. Smart list and program membership exports, run by your marketing operations team from our field list, under NDA. No user, nothing installed.
Our Marketo syncs with Salesforce. Isn’t that one database?
Two databases kept in step by a sync that can fail, lag or overwrite. We match both exports and show where they disagree about the same people.
We want AI to replace our scoring model. What do we check?
Whether the outcomes it would learn from, converted and won, are recorded consistently, and whether duplicates and dead addresses are inflating engagement.
Do you work on attribution?
We test whether the data behind attribution holds together across Marketo, the CRM and finance. We do not sell attribution tools.
