Product Introduction: You can create a form on n8n through which you can collect leads from interested user's.

You can also verify each user's email address to validate whether it's a valid email to make sure it lands on their inbox(suitable for those who have newletter / want's to send bulk email)

The leads with valid email will then get saved as a leads with the relevant field data to gmail, google sheets and discord(through webhook). You can add/remove any integration you feel like.

Setup Guide:

  1. Create Your Form: Begin by logging into your n8n account and navigating to the workflow editor. You can then customize your form fields to gather relevant information from your prospects, such as name, email address, and any additional data you require.

  2. Email Verification: After collecting the lead data, add an Email Verification node to validate each user's email address. This crucial step ensures that only genuine and deliverable email addresses are included in your lead database, maximizing the effectiveness of your outreach efforts. We have used hunter.io service in this, you can change it to any other service you need.

  3. Save Leads: Next, incorporate nodes to save your verified leads to various platforms for streamlined management. Utilize the Gmail node to store lead information directly in your Gmail account, ensuring easy access and organization. Additionally, leverage the Google Sheets node to archive lead data in a spreadsheet for comprehensive tracking and analysis.

  4. Integrate with Discord: For real-time notifications and collaboration, integrate n8n with Discord using the Webhook node. Configure the webhook to send lead information to your designated Discord channel, enabling your team to stay informed and coordinate effectively.

  5. Customize Integrations: Tailor your workflow by adding or removing integrations based on your specific requirements. Whether you prefer to connect with additional platforms or streamline your workflow further, n8n offers unparalleled flexibility to adapt to your business needs.

Experience the simplicity and efficiency of n8n to revolutionize your lead generation strategy and propel your success to new heights.

n8n Form Lead Collection and Enrichment

This n8n workflow automates the process of collecting form submissions, enriching the lead data, and then distributing it to various platforms like Google Sheets, Gmail, and Discord. It also includes conditional logic to send enriched leads to Hunter.io based on specific criteria.

What it does

This workflow streamlines your lead management by:

  1. Capturing Form Submissions: Listens for new submissions from an n8n form.
  2. Storing Raw Data: Appends the raw form submission data to a Google Sheet for record-keeping.
  3. Conditional Enrichment: Checks if the submitted form data contains an email address.
    • If an email is present:
      • Sends the lead details via email using Gmail.
      • Posts the lead details to a Discord channel.
      • Further Conditional Enrichment: Checks if the lead's email domain is "n8n.io".
        • If the domain is "n8n.io": Sends the lead's email to Hunter.io for further enrichment (e.g., finding more information about the company).
        • If the domain is NOT "n8n.io": Proceeds without Hunter.io enrichment.
    • If no email is present: Proceeds without email, Discord, or Hunter.io actions.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running n8n instance.
  • Google Sheets Account: Configured with an n8n credential to append data.
  • Gmail Account: Configured with an n8n credential to send emails.
  • Discord Account/Webhook: Configured with an n8n credential to post messages to a channel.
  • Hunter.io Account (Optional): If you wish to use the email enrichment feature for specific domains, you'll need a Hunter.io API key and credential configured in n8n.

Setup/Usage

  1. Import the Workflow: Import the provided JSON into your n8n instance.
  2. Configure Credentials:
    • Set up your Google Sheets credential.
    • Set up your Gmail credential.
    • Set up your Discord credential (e.g., a webhook URL).
    • (Optional) Set up your Hunter.io credential if you intend to use the email enrichment feature.
  3. Configure the n8n Form Trigger:
    • Activate the "On form submission" trigger node.
    • Copy the webhook URL provided by the trigger. This is the endpoint where your form submissions should be sent.
  4. Configure Google Sheets:
    • Specify the Spreadsheet ID and Sheet Name where you want to append the form data.
  5. Configure Gmail:
    • Specify the recipient email address, subject, and body for the lead notification emails. You can use expressions to include data from the form submission.
  6. Configure Discord:
    • Specify the channel ID or ensure your webhook is correctly configured to post to the desired channel.
    • Customize the message content to include relevant lead details.
  7. Configure Hunter.io (Optional):
    • If using Hunter.io, ensure the "If" node checking for the "n8n.io" domain (or your desired domain) is correctly configured.
    • The Hunter.io node should be set up to use the email address from the incoming lead data.
  8. Activate the Workflow: Once all configurations are complete, activate the workflow.

Now, any submission to the n8n form trigger's webhook URL will initiate this automated process.

Auto-reply & create Linear tickets from Gmail with GPT-5, gotoHuman & human review

This workflow automatically classifies every new email from your linked mailbox, drafts a personalized reply, and creates Linear tickets for bugs or feature requests. It uses a human-in-the-loop with gotoHuman and continuously improves itself by learning from approved examples. How it works The workflow triggers on every new email from your linked mailbox. Self-learning Email Classifier: an AI model categorizes the email into defined categories (e.g., Bug Report, Feature Request, Sales Opportunity, etc.). It fetches previously approved classification examples from gotoHuman to refine decisions. Self-learning Email Writer: the AI drafts a reply to the email. It learns over time by using previously approved replies from gotoHuman, with per-classification context to tailor tone and style (e.g., different style for sales vs. bug reports). Human Review in gotoHuman: review the classification and the drafted reply. Drafts can be edited or retried. Approved values are used to train the self-learning agents. Send approved Reply: the approved response is sent as a reply to the email thread. Create ticket: if the classification is Bug or Feature Request, a ticket is created by another AI agent in Linear. Human Review in gotoHuman: How to set up Most importantly, install the gotoHuman node before importing this template! (Just add the node to a blank canvas before importing) Set up credentials for gotoHuman, OpenAI, your email provider (e.g. Gmail), and Linear. In gotoHuman, select and create the pre-built review template "Support email agent" or import the ID: 6fzuCJlFYJtlu9mGYcVT. Select this template in the gotoHuman node. In the "gotoHuman: Fetch approved examples" http nodes you need to add your formId. It is the ID of the review template that you just created/imported in gotoHuman. Requirements gotoHuman (human supervision, memory for self-learning) OpenAI (classification, drafting) Gmail or your preferred email provider (for email trigger+replies) Linear (ticketing) How to customize Expand or refine the categories used by the classifier. Update the prompt to reflect your own taxonomy. Filter fetched training data from gotoHuman by reviewer so the writer adapts to their personalized tone and preferences. Add more context to the AI email writer (calendar events, FAQs, product docs) to improve reply quality.

Ai website scraper & company intelligence

AI Website Scraper & Company Intelligence Description This workflow automates the process of transforming any website URL into a structured, intelligent company profile. It's triggered by a form, allowing a user to submit a website and choose between a "basic" or "deep" scrape. The workflow extracts key information (mission, services, contacts, SEO keywords), stores it in a structured Supabase database, and archives a full JSON backup to Google Drive. It also features a secondary AI agent that automatically finds and saves competitors for each company, building a rich, interconnected database of company intelligence. --- Quick Implementation Steps Import the Workflow: Import the provided JSON file into your n8n instance. Install Custom Community Node: You must install the community node from: https://www.npmjs.com/package/n8n-nodes-crawl-and-scrape FIRECRAWL N8N Documentation https://docs.firecrawl.dev/developer-guides/workflow-automation/n8n Install Additional Nodes: n8n-nodes-crawl-and-scrape and n8n-nodes-mcp fire crawl mcp . Set up Credentials: Create credentials in n8n for FIRE CRAWL API,Supabase, Mistral AI, and Google Drive. Configure API Key (CRITICAL): Open the Web Search tool node. Go to Parameters → Headers and replace the hardcoded Tavily AI API key with your own. Configure Supabase Nodes: Assign your Supabase credential to all Supabase nodes. Ensure table names (e.g., companies, competitors) match your schema. Configure Google Drive Nodes: Assign your Google Drive credential to the Google Drive2 and save to Google Drive1 nodes. Select the correct Folder ID. Activate Workflow: Turn on the workflow and open the Webhook URL in the “On form submission” node to access the form. --- What It Does Form Trigger Captures user input: “Website URL” and “Scraping Type” (basic or deep). Scraping Router A Switch node routes the flow: Deep Scraping → AI-based MCP Firecrawler agent. Basic Scraping → Crawlee node. Deep Scraping (Firecrawl AI Agent) Uses Firecrawl and Tavily Web Search. Extracts a detailed JSON profile: mission, services, contacts, SEO keywords, etc. Basic Scraping (Crawlee) Uses Crawl and Scrape node to collect raw text. A Mistral-based AI extractor structures the data into JSON. Data Storage Stores structured data in Supabase tables (companies, company_basicprofiles). Archives a full JSON backup to Google Drive. Automated Competitor Analysis Runs after a deep scrape. Uses Tavily web search to find competitors (e.g., from Crunchbase). Saves competitor data to Supabase, linked by company_id. --- Who's It For Sales & Marketing Teams: Enrich leads with deep company info. Market Researchers: Build structured, searchable company databases. B2B Data Providers: Automate company intelligence collection. Developers: Use as a base for RAG or enrichment pipelines. --- Requirements n8n instance (self-hosted or cloud) Supabase Account: With tables like companies, competitors, social_links, etc. Mistral AI API Key Google Drive Credentials Tavily AI API Key (Optional) Custom Nodes: n8n-nodes-crawl-and-scrape --- How It Works Flow Summary Form Trigger: Captures “Website URL” and “Scraping Type”. Switch Node: deep → MCP Firecrawler (AI Agent). basic → Crawl and Scrape node. Scraping & Extraction: Deep path: Firecrawler → JSON structure. Basic path: Crawlee → Mistral extractor → JSON. Storage: Save JSON to Supabase. Archive in Google Drive. Competitor Analysis (Deep Only): Finds competitors via Tavily. Saves to Supabase competitors table. End: Finishes with a No Operation node. --- How To Set Up Import workflow JSON. Install community nodes (especially n8n-nodes-crawl-and-scrape from npm). Configure credentials (Supabase, Mistral AI, Google Drive). Add your Tavily API key. Connect Supabase and Drive nodes properly. Fix disconnected “basic” path if needed. Activate workflow. Test via the webhook form URL. --- How To Customize Change LLMs: Swap Mistral for OpenAI or Claude. Edit Scraper Prompts: Modify system prompts in AI agent nodes. Change Extraction Schema: Update JSON Schema in extractor nodes. Fix Relational Tables: Add Items node before Supabase inserts for arrays (social links, keywords). Enhance Automation: Add email/slack notifications, or replace form trigger with a Google Sheets trigger. --- Add-ons Automated Trigger: Run on new sheet rows. Notifications: Email or Slack alerts after completion. RAG Integration: Use the Supabase database as a chatbot knowledge source. --- Use Case Examples Sales Lead Enrichment: Instantly get company + competitor data from a URL. Market Research: Collect and compare companies in a niche. B2B Database Creation: Build a proprietary company dataset. --- WORKFLOW IMAGE --- Troubleshooting Guide | Issue | Possible Cause | Solution | |-------|----------------|-----------| | Form Trigger 404 | Workflow not active | Activate the workflow | | Web Search Tool fails | Missing Tavily API key | Replace the placeholder key | | FIRECRAWLER / find competitor fails | Missing MCP node | Install n8n-nodes-mcp | | Basic scrape does nothing | Switch node path disconnected | Reconnect “basic” output | | Supabase node error | Wrong table/column names | Match schema exactly | --- Need Help or More Workflows?
