MQL vs SQL Explained

MQL and SQL are staging labels in a B2B funnel. An MQL has shown interest that meets a marketing threshold, while an SQL meets a stricter, sales-ready criterion.

What Is an MQL?

Marketing-Qualified Leads (MQLs) have engaged with content—downloads, webinars, or repeated site visits—enough to meet a scoring threshold. They signal awareness and interest but may not be ready for a sales call.

What Is an SQL?

Sales-Qualified Leads (SQLs) have been vetted by sales or an automated rule for budget, authority, need, and timeline (BANT). They are actively evaluating solutions and warrant direct outreach from a sales rep.

How Does an MQL Become an SQL?

Transition occurs when additional signals—product-fit, firmographic match, and intent data—push the lead past a defined score. A human SDR or workflow flips the status from MQL to SQL in the CRM.

Why Does the MQL vs SQL Stage Matter?

Clear MQL and SQL stages prevent premature sales outreach, improve conversion metrics, and align marketing spend with revenue. Data engineers rely on these labels to model pipeline velocity accurately.

How to Define Scoring Thresholds?

Start by analyzing historical close-won deals. Identify common activities and attributes, assign points, and benchmark the score where win-rate sharply rises. Revise quarterly as campaigns and ICP evolve.

How to Track MQL & SQL in a Data Warehouse?

Ingest CRM and marketing-automation data into Snowflake, BigQuery, or Redshift. Use SQL to persist daily snapshots of lead_status, activity_counts, and score, enabling cohort and funnel analysis.

Why Use Galaxy for MQL & SQL Analysis?

Galaxy’s AI copilot creates, optimizes, and shares SQL that joins CRM, website, and product tables. Developers endorse canonical funnel queries in Galaxy Collections, eliminating Slack paste chaos.

Best Practices for Managing MQLs & SQLs

Align definitions in a revenue-ops charter, automate scoring logic, give bidirectional feedback between sales and marketing, and visualize funnel drop-offs weekly.

Common Pitfalls to Avoid

Static scoring models, ignoring negative signals, and missing hand-off SLAs cause leaks. Continuous data-driven refinement fixes them.

Why MQL vs SQL: A Data-Driven Guide to Lead Qualification is important

Accurate MQL and SQL definitions align marketing spend with revenue, prevent sales from engaging too early, and let data teams trust funnel metrics. Misalignment skews CAC, LTV, and pipeline forecasts.

MQL vs SQL: A Data-Driven Guide to Lead Qualification Example Usage


SELECT DATE(created_at) AS dt,
       SUM(CASE WHEN lead_stage = 'MQL' THEN 1 END) AS mql_cnt,
       SUM(CASE WHEN lead_stage = 'SQL' THEN 1 END) AS sql_cnt
FROM analytics.leads_daily_snapshot
WHERE created_at >= CURRENT_DATE - INTERVAL '30 day'
GROUP BY dt
ORDER BY dt;

Common Mistakes

Frequently Asked Questions (FAQs)

How many points should define an MQL?

Use historical analysis; many teams start near the 40–50 point range but tailor to your ICP.

Can a lead skip MQL and go straight to SQL?

Yes. High-intent actions like a pricing request can auto-label a lead as SQL.

How does Galaxy help with MQL/SQL dashboards?

Galaxy’s AI copilot writes join logic and version-controls the queries your RevOps team shares, speeding dashboard refreshes.

What data sources are required?

At minimum, CRM, marketing-automation, and website analytics tables feed the scoring model.
