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.

Frequently Asked Questions

Common questions about lead scoring and alert automation

MadKudu analyzes form submissions using predictive scoring models that evaluate lead quality based on company data, job titles, and behavioral signals. It assigns scores indicating conversion likelihood, helping sales teams prioritize outreach. Businesses typically see 30-50% higher conversion rates when focusing on MadKudu-qualified leads versus unqualified ones.

The system examines hundreds of attributes including company size, funding status, technology stack, and the lead's role in purchase decisions. MadKudu continuously improves its models based on your actual conversion data, becoming more accurate over time.

  • Scores range from 0 (unlikely to convert) to 100 (hot lead)
  • Integrates with CRMs to track lead-to-customer journeys
  • Requires minimal setup beyond API connection

This workflow works best with B2B contact forms, demo request forms, and lead capture forms where you need to qualify inbound inquiries. Ideal forms collect company name, job title, and email address - the key data points MadKudu analyzes for scoring. High-intent forms like pricing requests or free trial signups see particularly strong results.

For maximum effectiveness, ensure your forms capture enough firmographic data for accurate scoring. Forms with just name and email will produce less reliable scores than those also collecting company size, industry, and role information.

  • Best for forms with 50+ monthly submissions
  • Works with any form platform that can trigger webhooks
  • Multi-step forms should pass all collected data

The entire process - from form submission to Gmail alert - typically completes in under 2 minutes. MadKudu's API responds within seconds for scoring, and Hunter's email API delivers notifications immediately. This real-time alert system ensures your sales team can follow up while the lead is still engaged with your brand.

In practical terms, this means sales reps can be calling a hot lead before they've even left your website. The speed advantage is particularly valuable for competitive markets where first response time dramatically impacts conversion rates.

  • Average latency: 90-120 seconds end-to-end
  • No scheduled batches - processes each lead individually
  • Email delivery time depends on Gmail's servers

Yes, the n8n workflow includes editable parameters to adjust what qualifies as a 'great lead'. You can set minimum score thresholds, require specific company attributes, or only trigger alerts for certain form types. Most businesses start with MadKudu's recommended thresholds then refine based on their actual conversion data over time.

Advanced customization options include creating tiered alert levels (e.g. different notifications for scores 70-85 vs 85+) or combining score with other factors like lead source or requested product. The workflow's modular design makes these adjustments straightforward.

  • Thresholds adjustable per form or campaign
  • Can require specific company attributes
  • Multiple alert tiers possible

The alert includes the lead's name, email, company, MadKudu score, and key qualifying factors (like job title match or company size). You can customize the template to show any form data fields plus MadKudu's insights. Many teams add direct links to the lead's LinkedIn profile and company website for quick research.

Sample alerts typically highlight why the lead scored well (e.g. "VP at Fortune 500 company" or "Perfect fit for Enterprise plan") to help sales reps personalize their outreach. The template can also include suggested talking points based on the lead's form responses.

  • Default includes score + key attributes
  • Fully customizable email template
  • Can include enrichment data

Unlike basic form notifications that treat all submissions equally, this system filters out low-quality leads and highlights high-potential opportunities. Sales teams report spending 60% less time chasing dead-end leads while increasing conversions by focusing only on properly scored prospects. The automation also enriches raw form data with valuable context.

Traditional notifications create alert fatigue where reps ignore emails because most aren't worth following up. This solution ensures every notification represents a genuine sales opportunity worth immediate attention, dramatically improving response rates and team morale.
