1.1 Workflow description

Title: Qualify inbound leads from forms with Claude, Google Sheets, Slack and Gmail
Workflow name: Qualify inbound leads from forms with Claude, Google Sheets, Slack and Gmail

Quick Overview

This workflow captures inbound leads via an n8n Form, scores each submission against a plain-English ICP using Anthropic Claude, logs results to Google Sheets, and alerts hot leads via Slack and Gmail based on a configurable score threshold.

How it works

Receives a new submission from an n8n Form with lead details like name, email, website, budget, and needs.
Applies your configured ICP definition, hot-lead score threshold, Slack channel, and notification email to the incoming submission.
Sends the lead details and ICP to Anthropic Claude to return a structured fit score, tier, reasoning, and recommended next action.
Appends every scored lead to a Google Sheets “Leads” worksheet with the original form data and Claude’s outputs.
Checks whether the lead’s fit score meets or exceeds the configured threshold.
Posts a hot-lead alert to the specified Slack channel and sends a hot-lead email via Gmail when the threshold is met.

Setup

Add credentials for Anthropic, Google Sheets OAuth2, Slack, and Gmail OAuth2.
Update the Google Sheets document ID and ensure the workbook has a “Leads” sheet with columns that match the fields being appended.
Edit the ICP definition and hot-lead threshold, then set your target Slack channel and notification email in the configuration values.
Publish the n8n Form and share the form link wherever you collect inbound leads.

Find LinkedIn engagement opportunities with Apify, Gemini, Google Sheets and Slack

## Quick overview Youtube Video: https://youtu.be/ehsagyRmri4 This workflow runs on a schedule to scrape recent LinkedIn posts with Apify, stores and evaluates them in Google Sheets using Google Gemini, then enriches shortlisted authors with Apify profile data, saves profile results to a second Sheet, and sends Slack alerts for comment and connection opportunities. ## How it works 1. Runs on a schedule and sets the Ideal Customer Profile (ICP) text used for evaluation. 2. Scrapes LinkedIn posts from Apify using the configured search query and merges the results with existing rows from a Google Sheets “Linkedin_Outreach_oppurtunities” sheet. 3. Limits processing to two posts, upserts the post details into Google Sheets, and sends each post’s content to Google Gemini to score whether it is a comment opportunity. 4. If the post is marked as an opportunity with a confidence score above 80, the workflow updates the corresponding Google Sheets row with the AI reasoning and suggested comment angle. 5. Aggregates the qualified opportunities, compares their author profile URLs against an existing “Profile_scraper” Google Sheet, and keeps only authors that are not already present. 6. Scrapes each new author profile with an Apify profile scraper, uses Google Gemini to score ICP match, saves the profile details and qualification summary to the “Profile_scraper” Google Sheet, and posts a Slack message with the shortlisted profile link. 7. Separately, a Google Sheets trigger watches the opportunities sheet for row updates and sends a Slack alert containing the post link, reasoning, and comment angle. ## Setup 1. Add Apify credentials and verify the actor IDs and input parameters for the LinkedIn post scraper and the profile scraper. 2. Configure Google Sheets access (service account for read/write nodes and a Google Sheets Trigger OAuth connection) and update the document IDs/sheet tabs for both the opportunities sheet and the profile sheet. 3. Add Google Gemini (Google PaLM) credentials and confirm the selected Gemini model names in both AI evaluation steps. 4. Add Slack credentials, choose the target channel, and adjust the Slack message text if needed. 5. Customize the ICP text and the LinkedIn search query/posted time window to match the audience and volume you want to monitor.

Enrich existing HubSpot company records with Veridion

## Quick Overview This workflow manually enriches existing HubSpot companies using Veridion, skipping records already marked as enriched and updating HubSpot with matched company details like industry, location, and key firmographics. ## How it works 1. Runs when you manually execute the workflow. 2. Fetches up to 100 companies from HubSpot and includes key properties such as name, domain, phone, and the custom veridion_enriched flag. 3. Stops with a clear error if the veridion_enriched property is missing, otherwise filters to only companies not yet marked as enriched. 4. Retrieves full details for each selected HubSpot company and sends its name, domain/website, and phone to Veridion for enrichment. 5. Checks whether Veridion returns a match and skips companies without a match. 6. Maps key Veridion fields and updates the HubSpot company record with enriched details and sets veridion_enriched to true. ## Setup 1. Create the HubSpot company custom properties veridion_enriched (boolean/checkbox) and veridion_industry (single-line text). 2. Add HubSpot App Token credentials and ensure the HubSpot company list request includes veridion_enriched, veridion_industry, name, domain/website, phone, and hs_object_id. 3. Add Veridion API credentials and confirm your HubSpot companies have at least a name plus a domain/website or phone for best matching.

Identify company decision makers with Coresignal and Google Sheets

## Quick Overview This workflow manually pulls company website data from Google Sheets, finds matching companies in Coresignal, and searches for decision-maker employees. It then writes the resulting contact and company details back to a dedicated “Decision makers” sheet in Google Sheets. ## How it works 1. Manually starts the workflow and reads company rows from a Google Sheets spreadsheet. 2. Normalizes each company website URL into a clean domain and searches Coresignal for the matching company by website domain. 3. Processes companies in batches and writes placeholder “no employee found” company details to the “Decision makers” sheet in Google Sheets. 4. For each matched company, searches Coresignal for current employees whose titles match common executive and leadership roles. 5. If the title-based search does not return a single employee ID, runs a broader Coresignal decision-maker search that excludes HR-related roles and departments. 6. Retrieves detailed employee (and, when needed, company) fields from Coresignal and appends or updates the “Decision makers” sheet with names, titles, emails, LinkedIn URLs, and company information. ## Setup 1. Create a Google Sheets OAuth2 connection and set the source sheet (companies with a Website field) and the target “Decision makers” sheet in the Google Sheets nodes. 2. Create a Coresignal API credential in n8n and ensure your plan supports company and employee Elasticsearch DSL search and profile retrieval. 3. Confirm your input sheet includes a website column named either Website or website, and adjust the Coresignal title/department filters to match the decision-maker roles you want to capture.
