This article provides a complete, practical walkthrough of the Filter Form Send 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.

   ## Automate High-Quality Lead Filtering with n8n, Clearbit, and Gmail
   
   Managing incoming leads is a critical component of every business’s marketing and sales process. Yet, manually qualifying and responding to contacts can be both time-consuming and inconsistent. Enter n8n — the extensible, no-code workflow automation tool that lets you build powerful logic-based automations using intuitive drag-and-drop flow builders.
   
   In this article, we’ll walk through a real-world n8n workflow that automatically filters low-quality leads, enriches user data with Clearbit, evaluates the lead’s potential, and sends personalized emails via Gmail — all without lifting a finger.
   
   ---
   
   ## What This Workflow Does
   
   This specific n8n build automates a complete lead qualification pipeline based on business value. Here's a breakdown of the core logic:
   
   1. **Capture Lead Details** – a user fills out a "Contact Us" form using an n8n-native form trigger.
   2. **Clean Up Form Data** – the email field is mapped and cleaned to prepare for API enrichment.
   3. **Filter Out Personal Emails** – submissions using personal email domains like Gmail, Yahoo, or Hotmail are automatically disregarded.
   4. **Enrich User Data** – Clearbit is used to gather additional personal and business data based on the email address provided.
   5. **Enrich Company Data** – using the company domain received from Clearbit, more context is gathered about the user’s employer.
   6. **Qualify Leads** – if the company is tagged B2B and has more than 499 employees, it triggers further action.
   7. **Send Follow-Up Email** – a personalized thank-you email is sent using Gmail.
   8. **Discard Low-Quality Leads** – if the conditions are not met, the workflow ends without taking further action.
   
   This kind of automation ensures your team only focuses on meaningful leads, improving pipeline efficiency and customer experience.

   ## Step-by-Step Breakdown
   
   ### 1. Form Submission Trigger (n8n Form Trigger)
   The workflow begins with an embedded n8n form containing fields for the user’s role and business email. This form can be customized, branded, and hosted on your site.
   
   ### 2. Email Field Mapping
   To facilitate data handling later in the workflow, the submitted email is mapped to a variable. This step ensures consistent JSON structure for downstream nodes.
   
   ### 3. Filter Personal Emails
   To ensure that only business emails are considered, a filter node checks the submitted email against a list of common personal domains such as @gmail.com, @yahoo.com, etc. If the email is personal, the submission is quietly dropped.
   
   ### 4. Enrich Personal Data (Clearbit Person API)
   Clearbit is then used to look up the submitter’s professional information based on their email — including name, role, location, and current employer.
   
   ### 5. Enrich Company Data (Clearbit Company API)
   Using the domain of the submitter’s company, Clearbit retrieves detailed information about the business: industry tags (e.g., B2B, SaaS), technologies used, employee count, revenue, and more.
   
   ### 6. Lead Qualification Filter
   A conditional check is performed:
   - Is the company tagged as B2B?
   - Does the company have over 499 employees?
   
   If both criteria are met, the lead is considered high-quality.
   
   ### 7. Automated Gmail Response
   Qualified leads receive a personalized thank-you email via Gmail. The email dynamically includes the recipient's first name and assures them that the company will be in touch soon.
   
   ### 8. No-Op for Unqualified Leads
   If the criteria are not met, the workflow concludes immediately with no action taken. This prevents unnecessary spam or outreach for low-priority submissions.

   ## Why This Workflow Matters
   
   Qualifying leads manually can take countless hours. This smart workflow:
   
   - Reduces sales team overhead
   - Focuses attention on enterprise-level, high-conversion leads
   - Creates a frictionless user experience with auto-responses
   - Maintains a clean CRM by filtering out irrelevant contacts
   - Saves time and standardizes lead handling
   
   Best of all, all of this is achieved using no-code — no extra developers or integrations required beyond configuration.

   ## Tools & APIs Used
   
   This workflow uses the following third-party services:
   
   1. **Clearbit API (Person & Company Enrichment)**  
      Used to retrieve user and company metadata, such as role, company size, and industry tags.
   
   2. **Gmail API (via OAuth2)**  
      Used to send an automated and personalized email response upon successful lead qualification.
   
   3. **n8n Nodes**  
      - Form Trigger (native to n8n)
      - Filter & If Nodes (to control decision-making)
      - Set Node (for data mapping)

   ## Final Thoughts
   
   Whether you're running a startup or managing a large sales team, automating your lead capture and qualification flow is a game changer. n8n, paired with Clearbit and Gmail, offers a versatile and scalable way to turn raw form data into actionable business relationships.
   
   This workflow is a starter template — you can enhance it with Slack alerts, CRM integrations (like HubSpot or Salesforce), or automated scheduling links via Calendly. Thanks to n8n’s open and extensible nature, the possibilities are endless.
   
   If you haven’t started with n8n yet, now is the perfect time to incorporate intelligent automation into your workflow stack — no code required.

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.
