Email Analysis Agent

Email Analysis Workflow with DeepSeek V3

This project allows you to automatically analyze email threads and their attachments using AI. When you forward an email to specific email address, Zapier will trigger a webhook that processes the content and sends back an AI generated response suggestion.

Setup Instructions

For more detailed setup guide, see the [related blog post](https://upstash.com/blog/email-analysis-agent).

1. Set Environment Variables

This application uses **Resend** to send emails and **DeepSeek** for LLMs. To run the application, you need the following environment variables in the `.env` file.

DEEPSEEK_API_KEY=
QSTASH_TOKEN=
RESEND_API_KEY=

2. Deploy Your API Endpoint

First, deploy your API endpoint that will receive the webhook from Zapier. The endpoint should be accessible at

https:///analyze

You can also use `ngrok` to setup a publicly accessible endpoint on your local. See [local development guide](https://upstash.com/docs/workflow/howto/local-development)

3. Configure Zapier Integration

Step 1: Create a New Zap

1. Go to Zapier and click "Create Zap"

Step 2: Configure Gmail Trigger

1. Choose "Gmail" as your trigger app
2. Select "New Email" as the trigger event
3. Connect your Gmail account if not already done. This email address will be the account you'll forward the emails to get the response suggestions.
4. Optional: Add filters to only trigger on specific emails


Step 4: Configure Webhook Action

1. Add a new action step
2. Choose "Webhooks by Zapier"
3. Select "POST" as the action event
4. Configure the webhook with these settings:
