Definition
A Marketing Qualified Lead (MQL) is a prospect who has engaged with your marketing efforts and meets predefined criteria indicating readiness for sales outreach. MQLs typically show high engagement (webinar attendance, whitepaper downloads, email opens) and fit your target profile (company size, industry, title), signaling they are ready to move from marketing nurturing to sales conversations.
Key Characteristics
- Engagement-based: Has completed a meaningful marketing action (downloaded content, registered for a webinar, opened multiple emails, spent time on pricing page).
- Profile fit: Meets firmographic and demographic criteria (industry, company size, title, geography, budget range) indicating they are within your ICP.
- Recency: Shows recent engagement (within last 30-90 days) rather than historical interest, indicating active buying phase.
- Explicitly scored: Marketing team has applied lead scoring rules to consistently identify MQLs, removing subjectivity from the qualification decision.
Why It Matters for B2B/ABM
MQLs are the handoff point between marketing and sales. Without clear MQL definitions, marketing sends unqualified prospects to sales, wasting sales time. With clear definitions, sales focuses on prospects actually ready to engage.
MQL criteria vary by business model. For enterprise deals, MQL might require C-level engagement plus specific department visits (finance, ops). For SMB, MQL might be any prospect from an appropriate company size who downloads content. ABM teams customize MQL definitions by account segment and buying stage.
The MQL metric also measures marketing productivity. If marketing generates 100 MQLs monthly and only 10 convert to SAL (Sales Accepted Lead), either lead scoring is too loose or messaging doesn't resonate. Tight MQL standards improve sales efficiency and reveal marketing execution gaps.
Related Concept
Sales Accepted Leads (SAL) are MQLs that a sales rep has accepted as qualified; MQL is marketing's qualification, SAL is sales' acceptance of that qualification.
