AI Client Onboarding Agent: Auto Welcome Email Generator

This workflow automates welcoming new clients. When someone submits a form, their details are pulled from Google Sheets, a personalized onboarding checklist is generated using Google Gemini, and an email is sent directly to the client. It also includes error handling to ensure nothing is missed.


🟢 Section 1 – Trigger & Client Data Capture

Nodes:

  • ⏰ Trigger on New Client Form Submission → Fires when a new row is added in Google Sheets (from the client’s form).
  • đź§Ť Extract and Structure Client Data → Collects and formats client details: name, email, company, services, extra info.

âś… Beginner view: This is the doorway. When a client fills the form, their info is automatically pulled into the workflow.


📑 Section 2 – Checklist & Personalization

Nodes:

  • đź“‹ Client Checklist → Creates a default onboarding checklist (account setup, welcome call, docs, etc.).
  • đź§  Personalize Using Gemini → Sends client details + checklist to Google Gemini AI → generates a tailored onboarding email body.

âś… Beginner view: This is where the magic happens. Instead of a boring generic email, each client gets a customized message that feels personal.


📤 Section 3 – Delivery & Completion

Nodes:

  • đź“§ Send Email to Client → Sends the personalized onboarding email directly to the client’s inbox.
  • âś… Execution Completed → Marks the workflow as successfully finished.

✅ Beginner view: Think of this as the final handshake with the client — they get a warm, professional onboarding email without you lifting a finger.


🚨 Section 4 – Error Handling

Nodes:

  • ⚠️ Error Handler → Captures any failure in the workflow.
  • ❌ Execution Failure → Defines fallback/alert action if something breaks.

✅ Beginner view: This is your safety net. If an email fails or Gemini is unavailable, the workflow won’t just stop — you can set it up to alert you.
