This article provides a complete, practical walkthrough of the Hunter Form Create Triggered n8n agent. It connects HTTP Request, Webhook across approximately 1 node(s). Expect a Intermediate setup in 15-45 minutes. One‑time purchase: €29.

What This Agent Does

This agent orchestrates a reliable automation between HTTP Request, Webhook, handling triggers, data enrichment, and delivery with guardrails for errors and rate limits.

It streamlines multi‑step processes that would otherwise require manual exports, spreadsheet cleanup, and repeated API requests. By centralizing logic in n8n, it reduces context switching, lowers error rates, and ensures consistent results across teams.

Typical outcomes include faster lead handoffs, automated notifications, accurate data synchronization, and better visibility via execution logs and optional Slack/Email alerts.

How It Works

The workflow uses standard n8n building blocks like Webhook or Schedule triggers, HTTP Request for API calls, and control nodes (IF, Merge, Set) to validate inputs, branch on conditions, and format outputs. Retries and timeouts improve resilience, while credentials keep secrets safe.

   Streamlining Lead Qualification: A Smart Workflow Using n8n, Hunter, Clearbit, and HubSpot
   
   In the world of B2B sales, speed and accuracy are paramount when it comes to qualifying and enriching leads. Gathering contact information, verifying email addresses, researching companies, and updating your CRM can be time-consuming and error-prone if done manually. Fortunately, with workflow automation platforms like n8n, you can automate the majority of this process—saving time, reducing errors, and enabling your sales team to focus on closing deals.
   
   One powerful example is an n8n workflow that combines email capture with real-time verification and enrichment using Hunter and Clearbit, followed by automatic contact creation in HubSpot. Here’s an in-depth look at this workflow that delivers a seamless lead capture and qualification pipeline.
   
   📩 Step 1: Capture Leads via n8n Form
   
   The workflow kicks off with the “n8n Form Trigger,” which serves as a simple yet customizable lead capture form. In this case, the form asks one crucial question: “What's your business email?” Once a user enters their address, the workflow is triggered and the data begins to flow.
   
   💡 This form can be substituted with any other platform-supported form, including Typeform, Google Forms, or SurveyMonkey by adjusting the trigger accordingly.
   
   ✅ Step 2: Verify Email Validity with Hunter
   
   Next, the email address submitted is routed to the Hunter API, a powerful tool for email verification. This step determines whether the email is deliverable and valid (e.g., not disposable or malformed) using multiple reliability indicators like MX record verification and SMTP checks.
   
   The workflow evaluates the Hunter response: if the status is “valid,” it proceeds to the next steps. If the email is invalid, the workflow terminates with a no-operation node labeled “Email is not valid, do nothing.” This ensures only high-quality leads proceed through the system.
   
   🧠 Step 3: Enrich the Lead with Clearbit
   
   When a valid email is identified, the data is enriched in two phases via the Clearbit API:
   
   1. Enrich Person: Using the Clearbit People API, the workflow fetches personal details about the user—like their full name, job title, company, and LinkedIn profile—based on their email address.
   2. Enrich Company: The workflow then uses the company domain (derived from the person’s employment data) to gather deeper insights like company size, industry, technologies used, and location via the Clearbit Company API.
   
   This dual-enrichment process equips your CRM with comprehensive lead intelligence, arming your sales team with everything they need for personalized and effective outreach.
   
   📤 Step 4: Automatically Add Lead to HubSpot
   
   With all the rich data assembled, the workflow’s final step is to sync this information to HubSpot using its API. The contact is created with fields including:
   
   - Email
   - First Name and Last Name
   - Job Title
   - Company Name
   - Company Size
   
   Additional fields can be customized or expanded based on your organization's sales strategy, making this workflow highly adaptable.
   
   🎯 Bonus Tips & Ideas
   
   - Criteria-Based Lead Filtering: Use conditional logic between the enrichment and HubSpot steps to filter out unqualified leads (e.g., by company size, revenue, location, etc.).
   - Automate Further Actions: Trigger personalized email sequences or calendar invites for qualified leads using connected apps like Gmail, Outlook, or Calendly.
   - Real-Time Notifications: Send Slack alerts or internal emails to your team when high-value leads enter the system.
   
   🌐 Why This Workflow Matters
   
   This n8n-powered lead qualification pipeline eliminates manual data entry, validation, and enrichment tasks. It ensures your CRM only contains verified, high-quality leads enriched with valuable context—and all of that happens within seconds of form submission.
   
   It’s a reflective example of what makes n8n such a powerful workflow automation platform: low-code orchestration across APIs, real-time decision-making, and unparalleled customization. Whether you're a startup looking to scale or an enterprise trying to optimize operations, this workflow delivers immediate value.
   
   🚀 Final Setup Instructions
   
   To get this workflow up and running smoothly:
   
   1. Ensure your Hunter, Clearbit, and HubSpot credentials are correctly set in n8n.
   2. Test the form manually during development before activating the workflow.
   3. Customize form fields and HubSpot property mappings to match your use case.
   4. Use the production URL of the form trigger to deploy publicly on your site.
   
   With just a few API keys and clicks, your organization could move from lead chaos to lead clarity.

   By automating your lead capture, qualification, and enrichment journey, you empower your sales team with better insights and free them up from repetitive, manual tasks. Give your pipeline a productivity upgrade with this plug-and-play n8n workflow today.

5. Set credentials for each API node (keys, OAuth) in Credentials.
6. Run a test via Execute Workflow. Inspect Run Data, then adjust parameters.
7. Enable the workflow to run on schedule, webhook, or triggers as configured.

Tips: keep secrets in credentials, add retries and timeouts on HTTP nodes, implement error notifications, and paginate large API fetches.

Validation: use IF/Code nodes to sanitize inputs and guard against empty payloads.

Why Automate This with AI Agents

AI‑assisted automations offload repetitive, error‑prone tasks to a predictable workflow. Instead of manual copy‑paste and ad‑hoc scripts, your team gets a governed pipeline with versioned state, auditability, and observable runs.

n8n’s node graph makes data flow transparent while AI‑powered enrichment (classification, extraction, summarization) boosts throughput and consistency. Teams reclaim time, reduce operational costs, and standardize best practices without sacrificing flexibility.

Compared to one‑off integrations, an AI agent is easier to extend: swap APIs, add filters, or bolt on notifications without rewriting everything. You get reliability, control, and a faster path from idea to production.

Best Practices

• Credentials: restrict scopes and rotate tokens regularly.
• Resilience: configure retries, timeouts, and backoff for API nodes.
• Data Quality: validate inputs; normalize fields early to reduce downstream branching.
• Performance: batch records and paginate for large datasets.
• Observability: add failure alerts (Email/Slack) and persistent logs for auditing.
• Security: avoid sensitive data in logs; use environment variables and n8n credentials.

FAQs

Can I swap integrations later? Yes. Replace or add nodes and re‑map fields without rebuilding the whole flow.

How do I monitor failures? Use Execution logs and add notifications on the Error Trigger path.

Does it scale? Use queues, batching, and sub‑workflows to split responsibilities and control load.

Is my data safe? Keep secrets in Credentials, restrict token scopes, and review access logs.
