What is a marketing qualified lead?
A marketing qualified lead is a prospect who has demonstrated enough interest and fit to be worth passing to the sales team. Not every lead is worth a sales call -- an MQL is a lead that has crossed a threshold of engagement and profile match that suggests genuine purchase intent.
The concept exists to solve a common problem: marketing generates a flood of leads, but many are unqualified -- tire-kickers, students, competitors, or people who downloaded one piece of content and never returned. Without a qualification layer, sales wastes time on leads that will never convert, and the relationship between marketing and sales deteriorates.
Defining what makes a lead "qualified" varies by company. For some, it is a specific action like requesting a demo. For others, it is a combination of behavioral signals -- visiting certain pages, engaging with multiple emails, and matching a target company profile. The key is that marketing and sales agree on the criteria before leads start flowing.
