📄 What this workflow does

This workflow automates the process of finding LinkedIn leads and writing personalized outreach messages. It takes user input (keywords + purpose), generates a Boolean LinkedIn search query with Gemini, fetches up to 20 results via Google Custom Search API, logs them into Google Sheets, and then drafts custom outreach messages for each lead. Finally, the workflow updates the sheet and optionally sends you an email notification with the results.

👤 Who is this for

  • Sales and business development teams who want to automate LinkedIn prospecting.
  • Recruiters searching for candidates and generating outreach at scale.
  • Marketers or founders looking for potential partners, clients, or collaborators.
  • Anyone tired of manual LinkedIn searches and copy-pasting outreach messages.

✅ Requirements

  • Google Sheets account (with a sheet for storing LinkedIn leads + messages).
  • Google Custom Search Engine (CSE) enabled with "Search the entire web" and valid cx.
  • Gemini API access (for Boolean query generation + outreach message drafting).
  • SMTP credentials for optional email notifications.

⚙️ How to set up

  • Connect your Google Sheets account and select the sheet to store results.
  • Configure Gemini API credentials in n8n for both search query + outreach message generation.
  • Create a Google Custom Search Engine and note down the key and cx.
  • Update the HTTP Request node with your credentials (key, cx, hl, gl).
  • Set up SMTP credentials if you want email notifications.
  • Publish the Form trigger and test with sample keywords + purposes.

🔁 How it works

  1. Form Submit → Collects user input: keywords + purpose of contact.
  2. Gemini (Boolean Generator) → Creates a LinkedIn-specific search query (site:linkedin.com).
  3. Google Custom Search API → Fetches up to 20 matching profiles or company pages.
  4. Append to Google Sheets → Saves name, LinkedIn URL, description.
  5. Split & Loop → Processes each LinkedIn entry one by one.
  6. Gemini (Message Writer) → Generates personalized outreach messages using Purpose + company info.
  7. Update Google Sheets → Adds outreach message to the matching LinkedIn row.
  8. Optional Email Notification → Sends you a link to the updated sheet.

n8n Form Triggered Email Sender with Google Gemini

This n8n workflow provides a simple yet powerful automation for sending personalized emails based on form submissions, leveraging the intelligence of Google Gemini. It's ideal for scenarios where you need to collect information and then generate tailored responses or follow-ups.

What it does

This workflow automates the following steps:

  1. Triggers on Form Submission: The workflow starts when an n8n form is submitted.
  2. Generates Content with Google Gemini: It uses the data from the form submission to generate dynamic content (e.g., personalized email body, subject lines, or summaries) using Google Gemini.
  3. Sends Email: The generated content is then used to send an email to a specified recipient (or a recipient derived from the form data).
  4. Logs to Google Sheets: The form submission data and potentially the generated content are recorded in a Google Sheet for tracking and record-keeping.
  5. Loops for Multiple Items (Implicit): Although no explicit Split in Batches node is connected in the provided JSON, the presence of the "Loop Over Items" node suggests an intention to process multiple items if the input data structure allows for it, or to handle multiple fields from a single form submission.
  6. Makes HTTP Requests (Implicit): The "HTTP Request" node, while not connected, indicates a potential for integrating with external APIs or web services if needed, for example, to enrich data or trigger other systems.

Prerequisites/Requirements

To use this workflow, you will need:

  • n8n Instance: A running instance of n8n.
  • Google Gemini API Key: For the "Google Gemini" node to generate AI-powered content.
  • SMTP Credentials: For the "Send Email" node to send emails.
  • Google Sheets Account: With appropriate permissions for the "Google Sheets" node to write data.
  • An n8n Form: To trigger the workflow.

Setup/Usage

  1. Import the Workflow: Download the provided JSON and import it into your n8n instance.
  2. Configure Credentials:
    • Google Gemini: Add your Google Gemini API key as a credential.
    • Send Email: Configure your SMTP credentials for sending emails.
    • Google Sheets: Authenticate your Google Sheets account.
  3. Create an n8n Form Trigger: Set up the "On form submission" node with the desired form fields.
  4. Customize Google Gemini: Adjust the prompt in the "Google Gemini" node to generate the specific content you need based on your form fields.
  5. Configure Send Email: Map the output from the "Google Gemini" node (and potentially the form data) to the subject, body, and recipient fields of the "Send Email" node.
  6. Configure Google Sheets: Specify the Google Sheet and worksheet where you want to log the data, mapping the relevant fields from the form submission and Gemini output.
  7. Activate the Workflow: Once configured, activate the workflow to start processing form submissions.

If AI returns non-JSON, keep “Return only a JSON array” as the last line of the prompt and keep jsonOutput enabled. Consider adding validation on parsing.warnings to gate Salesforce writes. For discounts/taxes in OLI: Standard OLI fields don’t support per-line discount amounts directly; model them in UnitPrice or custom fields. Replace the Composite API URL with your org’s domain or use the Salesforce node’s Bulk Upsert for simplicity.
