Buyers who don't get burned by their lead generation agency ask three types of questions. How the agency finds the right people. How they qualify what they find. How they hold themselves accountable to what was agreed.
Everything else is filler.
Here are the ten questions to work through before you sign, in the order a buyer's brain moves through them. Green-flag and red-flag answers on each.
Targeting and methodology
1. How do you develop and align with our Ideal Customer Profile (ICP)?
Not a firmographic checklist. A real ICP includes decision-maker titles, industries, company size, and buying signals that indicate when an account is in-market. The agency should walk you through their approach before the SoW is signed, not after.
Green flag: signal-based ICP layered on firmographic filters, co-authored with you. Red flag: they hand you a template.
2. What channels and tools do you use for outreach?
Tool choices reveal how the work actually runs. Ask what they use for prospect data (Apollo, ZoomInfo, Clay), for sequencing (Instantly, Smartlead, HubSpot), and for deliverability infrastructure. Ask which channels they'll run for you (email, LinkedIn, phone) and why.
Red flag: "we have a proprietary system." That means unaudited.
3. How is your outreach personalized?
Generic messaging trains your ICP to ignore your brand. Ask for sample sequences before you sign. Ask how they iterate messaging when reply rates dip. What they show you is what they'll ship.
Leadle's answer: per-persona messaging, rebuilt every 4 to 6 weeks based on reply data. Sample sequences shared before contract signing.
Lead qualification
4. How do you define an MQL vs an SQL?
Post-signing friction almost always traces to a qualification definition that was never agreed on. A good SLA defines both terms in writing: who counts as a lead, what an appointment means, what a "positive response" looks like. All co-authored, all documented before launch.
Red flag: qualification defined unilaterally by the agency.
5. What's your lead verification process?
Purchased or scraped data kills sender reputation and pollutes your CRM. Ask how they source data, how often it's verified, and what the bounce-rate threshold is before they pause sending.
Green flag: multi-provider enrichment, verification at send-time, bounce threshold under 2%. Red flag: any variant of "we have a huge database."
Results and accountability
6. Can you share case studies or references from clients like us?
Two or three references at your ACV, cycle length, and vertical. Talk to them. If the agency won't name three, that's the answer.
7. What KPIs do you track and report on?
Meetings booked is a starting point, not the whole picture. You want to see meeting-to-opportunity rate, cost per qualified meeting, reply rate per persona, and pipeline value trended over time. Weekly, monthly, and quarterly cuts.
Red flag: they report volume only.
8. How do we agree on success metrics together?
The single most under-asked question. Success metrics should be defined before launch, documented in the SLA, and reviewed at every business review. If the agency defines success alone, they'll always meet it.
9. What does communication and reporting look like week-to-week?
Ask what the cadence looks like. A workable rhythm is weekly syncs during the ramp period, moving to bi-weekly once the campaign is stable. Both calendarised, not ad-hoc. Ask about the escalation path: who handles what when something goes wrong. Ask about the reporting tool (Slack, email, dashboard) and who owns updates.
Leadle's answer: weekly syncs for the first 6 weeks, then bi-weekly. Slack Connect for day-to-day, formal reports at cadence, three-level escalation matrix documented on day one.
10. What are your terms if goals aren't met?
Ask about replacement policy on unqualified meetings, cancellation terms, and what happens after the initial 3-month period. A 3-month minimum with a clear exit clause is standard. Anything longer without a performance review gate favours the agency (B2Bmeetings, 2026).
The real cost of a bad B2B lead
Every unqualified meeting has a price tag most teams never total up.
Fully-loaded AE cost runs ₹1,730 to ₹2,600 per hour. A meeting that should have been screened out consumes an hour of AE time plus prep and notes. Roughly ₹4,000 per meeting.
Add the infrastructure cost. Over-sending or under-verifying degrades sender reputation, and recovery takes 4 to 6 weeks. Add the CRM cost. Unqualified contacts poison reporting for six months: inflated top-of-funnel, misleading conversion rates, unreliable forecasting.
Rough all-in per bad meeting: ₹16,000 to ₹24,000. Ten in a quarter is ₹1.6L to ₹2.4L gone.
