What is Marketing Qualified Lead (MQL)?
A Marketing Qualified Lead (MQL) is a prospective contact that has engaged with top- or middle-of-funnel marketing collateral, such as downloading a whitepaper or attending a webinar. While MQLs demonstrate curiosity, they have not yet passed sales-readiness validation, requiring automated scoring and enrichment before sales engagement.
Why it matters for B2B
MQLs represent early buying intent, but treating all MQLs as ready for immediate sales outreach leads to rep frustration and wasted capacity. Without firmographic enrichment and intent gates, sales teams spend time following up on unqualified leads.
A structured GTM system enriches MQLs instantly with company headcount, tech stack, and role authority data. Only MQLs that pass exact ICP fit thresholds transition to Sales Accepted Leads (SAL) or Sales Qualified Leads (SQL).
