Ask a sales team what they need from marketing and the answer is usually some variation of: "better leads." Ask a marketing team why their leads aren't converting and the answer is usually: "sales doesn't work them properly."
Both observations are often simultaneously correct. The problem isn't that marketing is generating bad leads or that sales is being lazy. The problem is that the two teams have different definitions of "ready", and nobody has had the uncomfortable conversation required to align them.
The MQL-to-SQL handoff is where most B2B pipeline is lost. Not at the top of the funnel. Not in the close. At the moment where marketing says "this person is qualified" and sales says "I don't think so."
Why the definitions don't align
Marketing defines MQL based on what marketing can measure: engagement with content, lead score, form fills, website behaviour. These are genuine signals of interest. They are not signals of purchase intent, budget authority, or timeline alignment.
Sales defines SQL based on what closes deals: confirmed budget, decision-making authority, explicit problem statement, and a defined timeline. BANT, MEDDIC, whatever framework your sales organisation uses, the criteria are commercial, not behavioural.
The gap between the two definitions is not a technical problem. It's a data problem. Marketing doesn't have the information sales needs to do its job, because that information doesn't appear in email engagement data.
What the handoff email actually needs to contain
Every MQL passed to sales should come with a brief (four to six sentences) that answers the questions the sales rep will ask themselves before deciding whether to engage:
- What company, what industry, what approximate size?
- What role does this person hold, and is it a buying role?
- What have they engaged with? (Not "they scored 85 points." Which specific pages, which specific content?)
- What problem are they likely trying to solve, based on what they've consumed?
- Is there any indication of timeline or urgency?
If marketing can't answer questions one through four, the lead isn't ready to pass. The MQL threshold should require that information before the lead can be routed. This means progressive profiling, intelligent form design, and intent-data enrichment, not just lead scoring.
The 24-hour response SLA
Research across B2B sales cycles consistently shows that response time in the first 24 hours of a lead expressing high intent (demo request, pricing enquiry, free trial signup) is the single strongest predictor of whether that lead converts to an opportunity. Not nurture programme quality. Not email content. First-response time.
The marketing team's job is to identify high-intent signals as they happen and get that information to a sales rep within the response window. The sales team's job is to use that window. If either side fails, the lead cools.
Build the SLA into the CRM: when a lead crosses the decision-stage threshold, it triggers an alert to the assigned sales rep with a 24-hour response timer. If the lead isn't contacted within 24 hours, the alert escalates to the sales manager. This isn't punitive, it's a shared commitment to not wasting the leads that both teams worked to generate.
How to run the alignment conversation
The conversation that fixes the MQL-to-SQL problem is uncomfortable because it requires marketing to accept that their current MQL definition may not be useful to sales, and it requires sales to accept that their feedback needs to be specific enough for marketing to act on.
The structure that works: a monthly MQL review meeting, 45 minutes, with a shared spreadsheet of the last 30 MQLs passed. For each one: did sales engage? Did it become an opportunity? Why or why not? After three monthly reviews, patterns emerge. The patterns reveal either that the MQL definition is wrong, that specific channels are producing lower-quality leads than others, or that specific personas are underqualified in the nurture programme.
This conversation is the most valuable hour of alignment work a B2B marketing team can do. The teams that skip it spend the rest of the year debating whose fault the pipeline number is.
The feedback loop
The handoff only improves if sales feedback flows back into marketing's nurture programme. When a sales rep qualifies a lead and discovers it was misqualified, that data point should trigger a review: was the nurture content for this persona wrong? Was the scoring threshold too low? Was the lead-capture form collecting the wrong information?
Build a lightweight feedback mechanism in your CRM: when a sales rep marks an MQL as disqualified, prompt them for a one-word reason (wrong timing, wrong company size, wrong role, no budget, already solved). Aggregate those one-word reasons monthly. They'll tell you exactly where to fix the programme.
The B2B marketing-sales relationship is a feedback system. Marketing generates signals; sales converts them; the results flow back to improve the signal quality. When the feedback loop runs cleanly, both teams get what they want. When it breaks, everyone points at the pipeline number and argues about whose fault it is.
The email handoff is the most visible moment in the loop. Make it count.
