Marketing Qualified Lead vs. Sales Qualified Lead: A Field-Tested Breakdown

Let’s be clear—if your marketing team thinks they’re “crushing it” because downloads are up, but your sales team is ghosted on every call, you’ve got a lead quality problem.

And it usually starts with a fuzzy line between an MQL and an SQL.

Here’s how to get both teams speaking the same language—and how to build a system that turns curious prospects into closed deals.


What Is an MQL?

A Marketing Qualified Lead (MQL) is someone who has shown interest—but isn’t ready to buy yet.

They might:

  • Download a whitepaper
  • Subscribe to your newsletter
  • Attend a webinar
  • Visit your site five times in a week

They’re curious. They’re engaged. But they haven’t raised their hand to talk sales.

Your job at this stage: Nurture. Educate. Build trust.


What Is an SQL?

A Sales Qualified Lead (SQL) is someone who has shown clear buying intent.

They might:

  • Request a demo
  • Reply to an outbound message
  • Ask about pricing
  • Invite additional stakeholders into the conversation

They’re not just browsing. They’re evaluating—and your sales team should already be talking to them.

Your job at this stage: Connect. Qualify. Close.

If you’re treating every lead like an SQL—or worse, ignoring MQLs altogether—you’re leaking pipeline.


How to Move MQLs to SQLs (Without Forcing It)

  1. Lead Scoring
    Assign points for behaviors and firmographics. Don’t just score for clicks—score for meaningful action.
  2. Nurture Sequences That Educate, Not Annoy
    Send fewer, better emails. Make every follow-up feel like a value-add, not a nag.
  3. Sales Alerts Based on Behavior
    Set triggers for when an MQL becomes sales-ready: visiting your pricing page, watching a demo, booking a call.
  4. Tight Marketing-Sales Handoff
    Your sales team shouldn’t hear about a lead for the first time the day the meeting is booked. Sync weekly. Share context.

What to Do This Week

  • Review your lead definitions: Are your MQL and SQL criteria clear—and agreed upon by both teams?
  • Revisit your lead scoring model: Are you rewarding the right behaviors?
  • Audit your handoff process: Is sales getting full context, or just a name and email?
  • Create one piece of content designed to move MQLs to SQLs: Think demo request playbook, ROI calculator, or “what to expect” guide.
  • Track your MQL-to-SQL conversion rate—and start improving it.
