MQL, SAL, SQL: A Complete Guide to Lead Qualification Stages

Some companies add a manual step where sales reviews the MQL and confirms fit before accepting it as an SQL. A marketing qualified lead is a contact who has engaged enough with your marketing to indicate interest, but hasn't yet taken an action that signals they're ready to buy. A marketing qualified lead (MQL) is a prospect who has shown enough engagement and fit to warrant sales outreach. The key is maintaining consistent nurturing throughout the journey.
