Lead Quality Intent Evaluator
Score lead quality from corporate vs. personal email mix and close rates.
Only 55% use a work email, so a lot of sales effort goes to low-intent personal signups. Real-time enrichment or a business-email requirement would sharpen routing and protect rep time.
Email domain is a fast proxy for intent, not a verdict, some real buyers use personal addresses. Pair it with enrichment before hard-blocking anyone.
About this calculator
Not every signup is worth the same amount of sales attention, and email domain is a fast, if imperfect, proxy for which ones are. This evaluator splits your signups into corporate and personal email segments, applies each segment's own close rate, and shows the blended close rate and lead-quality score that mix actually produces.
How to use it
- Enter monthly signups and the share using corporate (work) email versus personal domains like Gmail or Outlook.
- Enter the close rate for corporate-email leads and separately for personal-email leads.
- Read expected customers split by segment, the blended close rate across all signups, the lead-quality score, and the low-intent share of your funnel.
Methodology
Corporate leads is signups × (corporate share ÷ 100); personal leads is the remainder. Corporate customers and personal customers are each segment's lead count × its own close rate, and total customers is the sum. Blended close rate is total customers ÷ signups.
The lead-quality score blends corporate share (weighted 0.7×) with a bonus for how much better corporate leads close relative to personal ones, capped at 100, so it rewards both a favorable mix and a meaningfully wider gap between segment close rates, not corporate share alone.
Corporate share of 60%+ is graded "good," 40-59% "warn," below 40% "bad," reflecting how much of your sales effort is likely going toward signups unlikely to close, based on the historical gap between segments.
FAQ
It's a fast proxy, not a verdict, some legitimate buyers, especially freelancers, founders, and smaller-company employees, use personal email addresses. Treat a personal-domain flag as a reason to enrich or verify rather than to automatically deprioritize or block a lead.
Then the quality signal here is weaker for your specific business, and the calculator will reflect that: a smaller close-rate gap between segments lowers the lead-quality score's bonus component, telling you domain-based routing matters less for your funnel than it might for a typical B2B SaaS company.
Common responses are adding real-time email or company enrichment at signup, requiring a business email for certain gated content, or routing personal-domain signups to a lower-touch nurture track instead of immediate sales outreach, protecting rep time for the higher-intent segment.
