What is MQL (Marketing Qualified Lead)?

A Marketing Qualified Lead (MQL) is a prospect that has met a defined threshold of engagement and fit criteria set by the marketing team, indicating sufficient interest to warrant sales attention. MQL definitions vary widely but typically include a combination of lead score thresholds, specific actions (content download, webinar attendance, pricing page visit), and firmographic fit. The MQL is the handoff point from marketing to sales, and poorly defined MQL criteria is one of the most common sources of sales-marketing misalignment — sales receives too many low-quality MQLs, or marketing sends too few.

MQL (Marketing Qualified Lead) is a critical concept for any B2B revenue team because it directly impacts pipeline predictability and revenue growth. Without a clear understanding of MQL (Marketing Qualified Lead), teams often make decisions based on incomplete information or misaligned frameworks — leading to poor forecasting, wasted outreach effort, and missed quota.

MQL (Marketing Qualified Lead) is closely connected to SQL (Sales Qualified Lead) and Lead Scoring, and several other core GTM concepts. In the context of GTM Engineering, MQL (Marketing Qualified Lead) typically informs how revenue systems are designed, what data is tracked, and how performance is measured.
