What This Workflow Does
This automation solves a critical challenge for sales teams: identifying and immediately acting on high-quality leads among hundreds of form submissions. Traditional form notifications flood inboxes with unqualified leads, wasting sales reps' time on low-probability prospects.
The workflow integrates MadKudu's predictive lead scoring with Hunter's email API to create a smart alert system. When a form is submitted, MadKudu analyzes the lead's attributes and assigns a quality score. Only submissions meeting your threshold trigger instant Gmail notifications to your sales team, ensuring they focus on the hottest opportunities.
How It Works
1. Form submission trigger
The workflow starts when a new submission comes through your web form (via n8n's webhook or form integration). The system captures all submitted data including contact information, company details, and any custom fields.
2. MadKudu lead scoring
The lead data is sent to MadKudu's API, which evaluates hundreds of signals including company attributes, job title relevance, and behavioral patterns. MadKudu returns a predictive score (0-100) indicating conversion likelihood.
3. Qualification check
The workflow compares the lead's score against your predefined threshold. If the score meets or exceeds your minimum quality standard, the process continues. Low-scoring leads are logged but don't trigger alerts.
4. Gmail notification via Hunter
For qualified leads, Hunter's API sends a formatted email alert to your designated Gmail address. The notification includes the lead's details, score, and key qualifying factors for immediate sales follow-up.
Pro tip: Set up a separate Gmail label/filter for these alerts to ensure they stand out from regular email traffic.
