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 β†’ Fires when a new row is added in Google Sheets (from the client’s form).
🧍 Extract and Structure Client Data β†’ Collects and formats client details: name, email, company, services, extra info.

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

πŸ“‘ Section 2 – Checklist & Personalization

Nodes:

πŸ“‹ Client Checklist β†’ Creates a default onboarding checklist (account setup, welcome call, docs, etc.).
🧠 Personalize Using Gemini β†’ Sends client details + checklist to Google Gemini AI β†’ generates a tailored onboarding email body.

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

πŸ“€ Section 3 – Delivery & Completion

Nodes:

πŸ“§ Send Email to Client β†’ Sends the personalized onboarding email directly to the client’s inbox.
βœ… Execution Completed β†’ Marks the workflow as successfully finished.

βœ… Beginner view: Think of this as the final handshake with the client β€” they get a warm, professional onboarding email without you lifting a finger.

🚨 Section 4 – Error Handling

Nodes:

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

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