Gmail and Hunter integration

Setup Time 5-10 minutes Problem 🚨 LinkedIn search is BROKEN. Personalized cold-emailing takes hours! I waste hours on LinkedIn manually filtering profiles, reading summaries, hoping they’d reply—tedious, frustrating, inefficient. But even after finding the email IDs of the contacts, the job to be done is incomplete. 𝗜 𝘄𝗮𝗻𝘁 𝘁𝗼 𝘀𝘁𝗮𝗿𝘁 𝗮 𝗰𝗼𝗻𝘃𝗲𝗿𝘀𝗮𝘁𝗶𝗼𝗻 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲𝘀𝗲 𝗰𝗼𝗻𝘁𝗮𝗰𝘁𝘀. If only I could type "𝘗𝘳𝘰𝘥𝘶𝘤𝘵 𝘮𝘢𝘯𝘢𝘨𝘦𝘳𝘴 𝘸𝘰𝘳𝘬𝘪𝘯𝘨 𝘰𝘯 𝘨𝘦𝘯𝘦𝘳𝘢𝘵𝘪𝘷𝘦 𝘈𝘐 𝘪𝘯 𝘠𝘰𝘶𝘛𝘶𝘣𝘦 𝘪𝘯 𝘕𝘦𝘸 𝘠𝘰𝘳𝘬" and seconds later have 10 personalized outreach emails in my Gmail drafts folder, ready for my review. It would save me hours of research effort! Introducing LinkGPT, a LinkedIn Agent, an automated agentic workflow powered by n8n. Prerequisites: Required accounts/API keys for Hunter.io, Google, and OpenAI. This would be helpful for: 🎯 Job Seekers wanting direct outreach to hiring managers (everyone applies to multiple jobs, and crafting personal emails takes hours!) 🎯 Recruiters looking to personalize candidate outreach at scale 🎯 Sales & Founders aiming for targeted customer conversations Step-by-step workflow: Takes 5-10 minutes to setup. Generate a Boolean search string for LinkedIn profiles. Perform authenticated Google searches using your query. Extract LinkedIn URLs and workplace context from the search results. Use OpenAI to extract first name, last name, and domain name from the context. Use Hunter.io to find emails of the contacts. Append all results to your connected Google Sheet. Columns: first_name, last_name, domain_name, email, context Read everything publicly available about your target profiles Identify common ground (shared backgrounds, interests, experiences) Craft highly personalized, thoughtful email drafts Automatically save tailored drafts in your Gmail and Google Sheets I put together a clear, step-by-step guide on setting this up yourself. Sample Query Sample: Input: "I am headed to NYC later this month, whom should I meet with that works in product management for gen AI products?" Output: List of 10 contacts with first name, last name, workplace, email address and context about them, and 10 personalized emails waiting for you review in your Gmail drafts folder

How can you find your target market if you don't know what your product is. This simple philosophy changes the way we think about automated sales agents. Context changes everything. In this 4-part workflow, we start by creating a knowledge base that will act as context across the workflow. This context will guide and provide our AI Agents across the workflow to locate better leads and perform market research based on what the product actually offers. Use Case: Lead generation for Product-based Sales Tech Required Neon DB**: For storing Research and Lead Data. You can use Google sheets but it has a rate limiting problem. Google Serper**: As a web search tool for our AI. Google Drive**: For storing our knowledge base documents. Pinecone**: Vector DB for converting our knowledge base into context for AI. Hunter.io**: For finding emails for outreach. Email Client**: An email client, maybe gmail or anything that can send an email on your behalf. Gemini**: Our trusty AI LLM. Good to know All of the tools that I use in this workflow are either free or have an extremely generous free-tier. How it works We start by converting our knowledge base into context for AI. Take in the documents from Google drive and convert it into embeddings and store them in a vector store like Pinecone. This needs to be only run once, or whenever you have a new document in your knowledge base. Then we pass this context to an AI agent and tell it to generate search queries for locating companies that actually need my services. Then for each company that we've located, we determine the company staff that we need to reach out to for selling our product. This will be done by a combination of Google Serper and Hunter.io Once we have the list of employees and their emails, we start creating personalized emails based on the data we've collected for each of the employee and send them outreach emails.

AI-Powered Automated Proposal & Lead Management System This advanced n8n workflow automates the transition from "Raw Lead" to "Sent Proposal." By integrating Email Verification, Large Language Models (LLMs), and Document Automation, it eliminates manual data entry and ensures that every proposal sent is personalized, professional, and delivered to a verified address. 🛠️ How It Works Data Intake & Validation The workflow is triggered via a Webhook. Before any processing occurs, the data passes through the Hunter node, which performs a real-time email verification check. Smart Error Handling: An If Node evaluates the verification result. If the email is invalid or "risky," the workflow redirects to a Respond to Webhook node, providing immediate feedback to the source and preventing wasted API credits on downstream nodes. The AI Agent Layer Once validated, the data reaches the Set Fields node to be mapped for the AI. Custom Prompt Logic: The AI Agent node, powered by Google Gemini, contains a sophisticated custom prompt. This prompt acts as a "template engine," instructing the AI to take specific input variables (like client name, project scope, and budget) and output a clean, professional HTML structure. This allows for dynamic content generation that adapts to the unique context of every lead. Professional PDF Generation Instead of sending a plain text email, the workflow passes the AI-generated HTML to the PDF Generator API. This tool renders the code into a high-quality, brand-consistent PDF document ready for client viewing. Automated Delivery & CRM Logging Gmail Integration: The final PDF is automatically attached and sent to the verified email address with a personalized message. Google Sheets Logging: To ensure full visibility, the workflow appends a row to a Google Sheet, tracking the date, client details, and the status of the sent proposal. 📋 Requirements To run this workflow, you will need active accounts and API credentials for the following services: n8n Instance: (Self-hosted or Cloud). Hunter.io API: For the email verification node. Google Gemini API: To power the AI Agent and custom prompt. PDF Generator API: To convert the AI's HTML output into documents. Google Workspace Account: Required for the Gmail (Sending) and Google Sheets (Logging) nodes. ⚙️ How to Set Up Follow these steps to get the workflow operational: Import the Workflow: Download the JSON file and paste it into your n8n canvas. Configure Credentials: Connect your Hunter API key. Set up your Google Gemini credentials (via Google Cloud Console). Add your PDF Generator API key. Authenticate your Google Account (OAuth2) for Gmail and Google Sheets. Customize the AI Prompt: Open the AI Agent node. Under the "System Message" or "Prompt" section, adjust the HTML template to match your brand's style and the specific fields you want to include in your proposal. Map your Google Sheet: Open the Append row in sheet node and select the specific spreadsheet and worksheet where you want to log your leads. Test the Flow: Use the Webhook simulator (Example DATA) to send a test payload and verify that the PDF is generated and the email is sent correctly.

Who’s this for 💼 This template is designed for teams and developers who need to generate PDF documents automatically from HTML templates. It’s suitable for use cases such as invoices, confirmations, reports, certificates, or any custom document that needs to be created dynamically based on incoming data. What this workflow does ⚙️ This workflow automates the full lifecycle of document generation, from request validation to delivery and storage. It is triggered by a POST webhook that receives structured JSON data describing the requested document and client information. Before generating the document, the workflow validates the client’s email address using Hunter Email Verification to prevent invalid or mistyped emails. If the email is valid, the workflow loads the appropriate HTML template from a Postgres database, fills it with the incoming data, and converts it into a PDF using PDF Generator API. Once the PDF is generated, it is sent to the client via Gmail, uploaded to Supabase Storage, and the transaction is recorded in the database for tracking and auditing purposes. How it works 🛠️ Receives a document generation request via a POST webhook. Validates the client’s email address using Hunter. Generates a PDF document from an HTML template using PDF Generator API. Sends the PDF via Gmail and uploads it to Supabase Storage. Stores a document generation record in the database. How to set up 🖇️ Before activating the workflow, make sure all required services and connections are prepared and available in your n8n environment. Create a POST webhook endpoint that accepts structured JSON input. Add Hunter API credentials for email verification. Add PDF Generator API credentials for HTML to PDF conversion. Prepare a Postgres database with tables for HTML templates and document generation records. Set up Gmail or SMTP credentials for email delivery. Configure Supabase Storage for storing generated PDF files. Requirements ✅ PDF Generator API account Hunter account Postgres database Gmail or SMTP-compatible email provider Supabase project with Storage enabled How to customize the workflow 🤖 This workflow can be adapted to different document generation scenarios by extending or modifying its existing steps: Add extra validation steps before document generation if required. Extend delivery options by sending the generated PDF to additional services or webhooks. Enhance security by adding document encryption or access control. Add support for additional document types by storing more HTML templates in the database. Modify the database schema or queries to store additional metadata related to generated documents. Adjust the data mapping logic in the Code node to match your input structure.
