Required Integrations

Email Integration

Why it's needed: The email integration is the foundation of this workflow. It monitors your inbox for new messages and sends automated replies on your behalf, ensuring seamless two-way communication without manual steps.

Setup steps:

Navigate to Integrations in your TaskAGI dashboard
Search for "Email" and select your email provider (Gmail, Outlook, etc.)
Click "Connect" and authorize TaskAGI to access your email account
Grant permissions for reading emails and sending messages
Verify connection by checking the green status indicator
Select your inbox from the dropdown menu
Save configuration and return to workflow builder

How to obtain credentials:

Gmail users: Use your Google account credentials; TaskAGI uses OAuth 2.0 for secure authentication
Outlook users: Sign in with your Microsoft account
Other providers: Generate an app-specific password from your email provider's security settings

Configuration in TaskAGI: Once connected, your email account appears as an available data source. The workflow automatically accesses:

Incoming email sender address ([[nodes.4.from]])
Email subject line ([[nodes.4.subject]])
Email body content ([[nodes.4.body]])
Timestamp and other metadata

OpenAI Integration

Why it's needed: OpenAI powers the intelligent decision-making in this workflow. It determines whether emails need responses and generates contextually appropriate, professional replies that match your business tone.

Setup steps:

Visit OpenAI's platform at platform.openai.com
Create an account or log in to your existing account
Navigate to API keys in your account settings
Click "Create new secret key" and copy the generated key
Return to TaskAGI and go to Integrations
Search for "OpenAI" and click "Connect"
Paste your API key in the authentication field
Test the connection by clicking "Verify"
Save configuration and confirm the green status indicator

How to obtain API keys:

Visit your OpenAI account dashboard at https://platform.openai.com/account/api-keys
Click the "Create new secret key" button
Copy the key immediately (it won't be shown again)
Store it securely—never share it publicly
You can generate multiple keys for different purposes

Configuration in TaskAGI: The OpenAI integration enables two critical nodes:

Decision node (Node 6): Uses gpt-4o-mini for fast, cost-effective analysis
Response generation (Node 8): Uses gpt-4o for higher-quality, nuanced replies

Configuration Steps

Step 1: Define Your Agent Identity (Nodes 1-3)

These informational nodes establish your agent's purpose and context.

Node 1 - Agent Name Options:

Enter a descriptive name like "Intelligent Email Response Agent" or "Customer Support Auto-Responder"
This helps you identify the workflow in your dashboard

Node 2 - Category & Industry:

Select your industry (e.g., "Technology," "E-commerce," "Professional Services")
Specify your business category to help AI understand context
Example: "SaaS Customer Support" or "Real Estate Sales"

Node 3 - How This Agent Works:

Document your email response strategy
Example: "This agent reviews incoming emails, determines if a response is needed, and generates professional replies matching our brand voice. It prioritizes customer inquiries and filters out spam/newsletters."

Step 2: Set Up Email Monitoring (Node 4)

Node 4 - New Email Received:

This trigger node requires no configuration—it automatically activates when emails arrive
Verify the email integration is connected (see Required Integrations section)
The node captures: sender address, subject, body, and timestamp

Step 3: Configure Business Context (Node 5)

Node 5 - Your Business Information: This critical node provides context for AI decision-making and response generation.

Configure these fields:

Company Name: "Your Company Name"
Industry: "Your Industry"
Business Description: "Brief description of what you do" (2-3 sentences)
Response Guidelines: "Always be professional, friendly, and solution-focused. Avoid technical jargon."
Tone of Voice: "Professional yet approachable" or "Formal and corporate"

Example configuration:

Company: Acme Tech Solutions
Industry: Software Development
Description: We provide cloud-based project management tools for remote teams
Guidelines: Respond within 24 hours, offer solutions, escalate complex issues
Tone: Friendly, professional, solution-oriented

Step 4: Configure Decision Logic (Node 6)

Node 6 - Determine If Reply Needed: This node uses AI to analyze whether an email requires a response.

Key settings:

Model: gpt-4o-mini (fast, cost-effective)
Prompt: The system prompt is pre-configured but you can customize it
Input: Automatically receives email content from Node 4
Output: Returns a decision (yes/no) to Node 7

Customize the decision criteria by editing the prompt to specify:

Types of emails that need responses (customer inquiries, sales leads, etc.)
Types to skip (newsletters, automated notifications, spam)
Priority rules (urgent emails always get responses)

Step 5: Set Up Conditional Routing (Node 7)

Node 7 - Needs Reply?: This node routes emails based on the decision from Node 6.

Configuration:

True path → Routes to Node 8 (Draft Email Response)
False path → Routes to Node 11 (No Reply Needed)
No manual configuration needed; this is automatic

Step 6: Configure Response Generation (Node 8)

Node 8 - Draft Email Response: This node generates your actual email reply using advanced AI.

Key settings:

Model: gpt-4o (highest quality for customer-facing content)
Prompt: Pre-configured to reference business information from Node 5
Context variables: Automatically includes:
- Original email content
- Sender information
- Your business guidelines
- Tone preferences

The prompt structure includes:

You are responding to an email as [Company Name]. 
Business context: [Business Description]
Tone: [Tone of Voice]
Guidelines: [Response Guidelines]
Original email: [Email Content]
Generate a professional, helpful response.

Step 7: Clean HTML Response (Node 9)

Node 8 - Clean HTML Response: This function removes formatting artifacts and ensures email compatibility.

What it does:

Strips unnecessary HTML tags
Converts markdown to plain text or safe HTML
Ensures compatibility with all email clients
Removes any potentially problematic formatting

No configuration needed—this runs automatically on Node 8's output.

Step 8: Configure Email Sending (Node 10)

Node 10 - Send Reply: This node sends your generated response back to the original sender.

Automatic configuration:

To: [[nodes.4.from]] (original sender's address)
Subject: Re: [[nodes.4.subject]] (original subject with "Re:" prefix)
Body: [[nodes.9.cleaned]] (cleaned response from Node 9)

Verify settings:

Confirm the "from" address matches your email account
Check that subject line formatting looks correct
Ensure body content is properly formatted

Step 9: Configure No-Reply Path (Node 11)

Node 11 - No Reply Needed: This node handles emails that don't require responses.

Configuration:

Set to No Operation (default)
Optionally add logging to track skipped emails
Consider adding a note for your records

Testing Your Agent

Pre-Launch Testing

Step 1: Verify integrations

Go to Integrations dashboard
Confirm both Email and OpenAI show green status
Test email connection by sending a test message to your inbox
Test OpenAI by running a simple completion

Step 2: Run a test execution

Click "Test Workflow" in the workflow builder
Provide a sample email as input:
- From: test@example.com
- Subject: Question about your services
- Body: Hi, I'm interested in learning more about your product. Can you send me pricing information?
Monitor the execution in real-time

Step 3: Verify each node

Node 4: Confirm email data is captured correctly
Node 5: Verify business information is loaded
Node 6: Check decision logic (should return "needs reply")
Node 8: Review generated response quality
Node 9: Confirm HTML is cleaned properly
Node 10: Verify email would be sent to correct address

Step 4: Check expected results

✅ Decision node correctly identifies emails needing responses
✅ Generated responses are professional and relevant
✅ Responses reflect your business tone and guidelines
✅ Email formatting is clean and readable
✅ Sender and subject information is correct

Success Indicators

Your agent is working correctly when:

Response quality: Generated emails sound natural and professional
Decision accuracy: Emails that need responses are identified correctly
