What makes a lead an MQL?

Whatever the two functions have agreed and written down. There is no external standard — which is why the definition, and the fact that both sides accept it, matters far more than where the threshold sits.

What is the difference between an MQL and an SQL?

An MQL is marketing's judgement that a lead is worth sales attention. An SQL is sales confirming it after contact. The gap between the two counts is the most informative number the pair produces.

Why do sales teams ignore MQLs?

Usually because acceptance is ceremonial — there is no real path to reject a lead and no feedback returned upstream, so the definition never corrects and the label stops carrying information.

Should MQL be a volume target?

Only paired with a downstream quality measure from a later period. An MQL volume target on its own is trivially met by lowering the threshold, which is the textbook case of a measure that improves as the outcome worsens.

Marketing Qualified Lead (MQL)

A lead that marketing considers ready for sales attention, according to a definition both teams have agreed. Without that agreement it is a marketing activity metric wearing a pipeline costume.

What it is

A lead that marketing judges ready for sales contact — a handoff point, not a property of the person. The label carries information only to the extent that the receiving function agrees with the judgement.

The definition matters more than the threshold

Debate usually settles on where to set a score threshold. The more consequential question is what the label is asserting: that the person has a problem the product solves, that they have some authority or access to it, and that the timing is plausible. A threshold without that agreement is a number both sides interpret differently.

The test of a working definition

Show ten records to a marketer and a seller separately and ask each whether it qualifies. Agreement above roughly eight suggests a shared definition. Below that, the disagreement is definitional and no scoring change will resolve it.

The two measures that matter

Acceptance rate — of leads passed as MQL, the share sales accepts. Low means the definition is not shared. Near 100% with poor downstream conversion means acceptance is ceremonial and the step is doing no work.
Conversion to opportunity, measured on the cohort rather than the period. Track each month's MQLs forward, because a rate computed from this month's MQLs and this month's opportunities compares two different populations.

Making the handoff work

Give rejection a real path with a reason code, and return it upstream. A qualification step with no possible rejection generates no information and cannot improve.
Pair any MQL volume target with a downstream measure from a later period. Volume alone is met by lowering the bar.
Measure time to first touch as a distribution, not a mean. The tail is where the loss is, and the mean conceals it.
Revisit the definition on a schedule. Product changes and new segments make an accurate definition wrong without anyone deciding to change it.

Where the concept breaks down

In account-based motions the unit of interest is the account, not the individual, and a single-person MQL can misrepresent buying-group activity. In product-led motions the meaningful signal is usage, which the product-qualified lead exists to capture. Retaining an MQL stage in either case tends to preserve a reporting artefact rather than a real decision point.

RELATED TERMS

Lead Scoring

A model assigning a numeric value to leads based on fit and behaviour, so attention goes to the ones most likely to convert.

Lifecycle Stages

The shared sequence describing a contact's relationship with the company over time — subscriber through customer — used to align marketing, sales and customer success on where someone is.

Sales Qualified Lead (SQL)

A lead that sales has examined and accepted as a genuine opportunity worth working. The point at which pipeline responsibility formally transfers.

Service Level Agreement (SLA)

An internal commitment between teams — typically how quickly sales will work a lead marketing delivers, and what quality standard marketing will deliver.
