How to Automate Lead Routing With Clearbit Data
Enrichment is only useful if it changes what happens next. The highest-leverage use of Clearbit is not display — it is routing. Enrich the lead, score it, and send it to the right rep or into nurture, without a human touching it.
This guide builds that pipeline: enrichment on form submit, a scoring rule, and routing logic. It builds on a working Clearbit API key.
Why enrich before routing?
Because a raw signup gives you almost nothing to route on — just an email and maybe a company name. Enrichment adds employee count, industry and location, which are exactly the fields routing rules depend on. Without it, every lead looks the same and you route by round-robin. The Clearbit company object gives you those fields in one call keyed off the email domain.
How do I add enrichment to a form submit?
- Capture the work email on submit.
- Extract the domain and call Clearbit Company lookup server-side.
- Attach the returned fields to the lead record.
- Handle the no-match case explicitly — route unknown domains to a default queue.
Step 4 matters more than it looks. If you do not plan for empty results, small-company signups fall through the cracks silently.
How do I build the scoring rule?
Keep it simple and legible. A workable starting score:
| Signal | Points |
|---|---|
| Employees 50-1000 | +30 |
| Target industry match | +25 |
| Target geography | +20 |
| Known tech-stack match | +15 |
| Free email domain | -20 |
Above a threshold, route to an AE. Below, put them in a nurture sequence. Write the rule down and review it quarterly — scoring rules rot as your ICP shifts.
How do I implement routing logic?
After scoring, branch on territory and size. Enterprise-size leads go to a named AE by region; mid-market goes into a pooled queue; small or unknown goes to self-serve. If your stack is a CRM plus a workflow tool, this is an if-then chain on the enriched fields. Keep the decision in one place so it is debuggable — scattered routing rules across three tools are impossible to reason about.
Clearbit enrichment vs building routing on form answers only
Self-reported form data is often wrong or blank; people skip the company-size field. Enrichment fills it reliably for established companies and costs a lookup each. The trade is accuracy and coverage versus cost and the black hole of small companies. A hybrid works best: enrich, then let self-reported data override when it conflicts and the lead is high value.
What breaks in practice?
Latency. If you call enrichment synchronously on the page, slow lookups stall the form. Call it server-side after the submit is acknowledged, then update routing a moment later. Also watch personal-email signups — Gmail addresses will not enrich, so treat them as a distinct segment rather than errors. And cache by domain; a popular company signing up ten times should cost one lookup, not ten.
Quick Summary
- Enrich leads on submit to get the fields routing rules need, then score and route.
- Handle no-match domains explicitly instead of letting them fall through.
- Keep a written scoring table and review it quarterly.
- Enrich server-side after acknowledging the form, and cache by domain to control cost.
