   • Netn will provide a local URL, typically http://localhost:5678 (or http://localhost:25678 as mentioned in the webinar). Open this URL in your web browser to access the Netn interface.

Step 2: Initiating Your Workflow in Netn

Once you’re in the Netn interface:

1. Create a New Workflow: Click on “Workflow” in the left sidebar, then select “New Workflow.” This opens a blank canvas where you’ll build your automation.
2. Add a Manual Trigger: Click the large “+” icon (or the one in the top right). Search for “Trigger” and select “Manual Trigger.” This node will allow you to initiate your workflow with a click, perfect for testing.

3. Add a Google Sheets Node: Click the “+” icon again. Search for “Google Sheets” and select the “Google Sheets” node. Drag it onto your canvas. This node will be responsible for fetching data from your spreadsheet.

   • Configure Action: In the Google Sheets node settings, ensure the “Operation” is set to “Get Many” or “Get Rows” (depending on the Netn version). This tells Netn to pull multiple rows of data from your sheet.

Step 3: Navigating Google Cloud Console for API Access

This is the most critical and complex part of setting up your Automated personalized email Netn workflow. Patience and precision are key!

1. Access Google Cloud Console: Go to https://console.cloud.google.com/ (DoFollow) and log in with your Google account.

2. Create a Project:

   • In the top bar, click on the project dropdown (usually showing “My First Project” or your organization’s name).
   • Click “New Project.”
   • Give your project a descriptive name (e.g., “Netn Email Blaster,” “Testing Webinar Netn AI”). The name doesn’t affect functionality.
   • Click “Create.”
   • Once created, ensure your new project is selected in the project dropdown.

3. Enable Required APIs:

   • Use the search bar at the top of the Google Cloud Console.
   • Search for and enable the following APIs, one by one:
   • Gmail API: Select “Gmail API” and click “Enable.”
   • Google Sheets API: Select “Google Sheets API” and click “Enable.”
   • Google Drive API: Select “Google Drive API” and click “Enable.” (Google Sheets are stored in Google Drive, so access is necessary).

4. Create OAuth Client ID Credentials:

   • In the left sidebar, navigate to “APIs & Services” > “Credentials.”
   • Click “+ Create Credentials” at the top and select “OAuth client ID.”

   • Configure Consent Screen (if prompted): This is for user consent.

     • Choose “External” for User Type. Click “CREATE.”

     • App Information:

       • App Name: Enter a name (e.g., “Netn Email Workflow”).
       • User Support Email: Select your email address.
       • Developer Contact Information: Enter your email address again.
       • Click “SAVE AND CONTINUE.”
     • Scopes: For now, click “SAVE AND CONTINUE.” We’ll refine scopes later.

     • Test Users: Under “Test users,” click “+ ADD USERS” and add the Google account you’re using for this setup. This is crucial as your app is still in “Testing” status. Click “SAVE AND CONTINUE.”

     • Review and click “BACK TO DASHBOARD.”

   • Back to Create OAuth Client ID: Now that the consent screen is configured, go back to “Credentials” and click “+ Create Credentials” > “OAuth client ID” again.

   • Application Type: Select “Web application.”
   • Name: Give it a name (e.g., “Netn Testing Webinar”). This helps you identify it later.

   • Authorized Redirect URIs: This is vital. In your Netn Google Sheets node (back in your Netn tab), locate the “OAuth Redirect URL” field within the credentials setup. Click the “Click to copy” button next to it. Paste this URL into the “Authorized redirect URIs” field in Google Cloud.

   • Click “CREATE.”

   • Copy Client ID and Client Secret: Google will display your “Client ID” and “Client Secret.” Copy both of these immediately and keep them safe. You’ll need them in the next step.

5. Refine Data Access Scopes:

   • Still in the Google Cloud Console, navigate to “APIs & Services” > “OAuth consent screen” (in the left sidebar).
   • Go to the “Scopes” tab.
   • Click “ADD OR REMOVE SCOPES.”
   • Search for and select all available scopes related to:

   • Gmail API: Grant full access for now (for testing purposes). Caution: In a production environment, only grant the minimum necessary permissions.

   • Google Sheets API: Select both available scopes.
   • Google Drive API: Select all available scopes.
   • Click “UPDATE” at the bottom, then “SAVE.”

Step 4: Connecting Google Sheets to Netn

Now, return to your Netn workflow:

1. Enter Credentials: In the Google Sheets node’s “Credentials” section, paste the “Client ID” and “Client Secret” you copied from the Google Cloud Console.
2. Authorize Connection: Click “Sign in with Google.” A pop-up window will appear asking you to select your Google account and grant permissions. Continue through the prompts, acknowledging the “This app isn’t verified” warning (normal for testing apps). You should see “Connection successful” and the credential turn green in Netn.

3. Configure Sheet Details:

   • Spreadsheet ID: Select your specific Google Sheet from the dropdown list.
   • Sheet Name: Select the relevant sheet (e.g., “Sheet1”).
4. Test the Connection: Click “Execute Node” at the bottom of the Google Sheets node. You should see the data from your spreadsheet appear in the “Output” section, confirming Netn can now read your data.

Step 5: Leveraging AI with the Basic LLM Chain Node

This is where the magic of personalization happens!

1. Add a Basic LLM Chain Node: Click the “+” icon after your Google Sheets node. Search for “Basic LLM Chain” and add it to your workflow.
2. Configure Prompt Source: In the Basic LLM Chain node settings, change “Source of Prompt” to “Define Below.”

3. Add OpenAI Credentials:

   • Click “Create New Credential” under “OpenAI API Key.”

   • Generate API Key: Go to https://platform.openai.com/ (DoFollow). Log in or sign up. Navigate to “API keys” on the left sidebar, then click “+ Create new secret key.” Give it a name and copy the key.

   • Add Credit: Ensure you have added credit to your OpenAI account’s billing section. The API usage consumes credits.
   • Paste your OpenAI API key into Netn and save the credential. Netn will test the connection, and it should turn green.
   • Select Model: Choose your desired OpenAI model (e.g., gpt-4o-mini or gpt-4).

4. Set System Message (AI’s Role): Click “Add From Prompt” and select “System Message.” This defines the AI’s persona and task. Use a clear, direct prompt like:

   "You are a highly skilled copywriting expert specializing in crafting engaging and personalized email marketing messages. Your primary task is to generate compelling email content based on the provided company data. Maintain a professional, friendly, and persuasive tone, avoiding any generic phrasing. Ensure the email subject line is captivating and the body content directly addresses the recipient's company, industry, and expressed needs."
   

5. Set User Message (Dynamic Data Input): Click “Add From Prompt” and select “User Message.” Use Netn’s expression editor (click the “Expression” button) to dynamically pull data from your Google Sheets node. This is how you feed personalized information to the AI:

   "Below is the data for a potential client. Please use this information to create a highly personalized email.
   
   Client Name: {{ $json["Name"] }}
   Client Email: {{ $json["Email"] }}
   Company Name: {{ $json["Company"] }}
   Industry: {{ $json["Industry"] }}
   Company Info: {{ $json["Information"] }}
   Current Status: {{ $json["Status"] }}
   
   Remember to be professional, friendly, and persuasive. The goal is to initiate a positive conversation about how our services can specifically benefit their company based on the provided details."
   

6. Require Specific Output Format: To ensure the AI’s response is structured and easy to use in subsequent nodes, enable “Require specific output format.”

7. Set Output Parser: After enabling specific output format, a new field “Output Parser” appears. Click “Add From Prompt” and select “Structured Output Parser.” Define the JSON structure for the AI’s output. This tells the AI exactly how you want its response organized:

   {
   "subject": "A compelling and personalized email subject line.",
   "destination_email": "The email address of the recipient, extracted from the input data.",
   "email_content": "The full body of the personalized email, including a clear call to action and a professional closing from 'Sofia, Head of Marketing at PT Kerbau Kecap'.",
   "delivery_status": "Set this to 'terkirim' (sent) once the email content is generated and ready for sending."
   }
   

   • Self-correction from transcript: Ensure you maintain proper JSON format. Commas separate key-value pairs, but the last pair in an object should not have a trailing comma.
   • Prompting for a specific sender identity (“Sofia, Head of Marketing at PT Kerbau Kecap”) directly in the JSON instruction ensures consistency, as discussed in the Q&A section of the webinar.
8. Test the LLM Chain: Click “Execute Node” on the Basic LLM Chain. Observe the output. It should now be structured JSON with a personalized subject, content, and the delivery_status set to “terkirim.”

Step 6: Crafting and Sending Personalized Emails via Gmail

Now, let’s connect the AI’s personalized output to your Gmail account for sending.

1. Add a Gmail Node: Click the “+” icon after the Basic LLM Chain node. Search for “Gmail” and add the node.

   • Configure Action: Set the “Operation” to “Send Message.”
2. Use Existing Credentials: Under “Credentials,” select the Google OAuth credential you created earlier (the one used for Google Sheets). This allows Gmail access through the same authorized connection.

3. Map Email Fields: Use Netn’s expression editor to dynamically populate the email fields:

   • To: {{ $json["destination_email"] }} (pulls the recipient email from the AI’s output)
   • Subject: {{ $json["subject"] }} (pulls the personalized subject from the AI’s output)
   • Email Type: Select “Text” (or “HTML” if your AI generates HTML content).
   • Message: {{ $json["email_content"] }} (pulls the personalized email body from the AI’s output)
4. Disable Netn Attribution: To remove the “This email was automatically sent by Netn” footer, go to “Add Option” in the Gmail node settings, find “Append Attribution,” and toggle it off.

5. Adding Attachments (Optional, Advanced): If you need to send attachments (like a company profile), you’ll need an additional node, typically a “Google Drive” node set to “Download a File.”

   • Add a Google Drive node before the Gmail node.
   • Configure it to download the specific file you want to attach.
   • In the Gmail node, click “Add Option,” then select “Attachments.” Use an expression to reference the output of the Google Drive node, ensuring the output name (e.g., “attachment”) matches the input expectation. This often involves binary data handling and might require a deeper dive into Netn’s data manipulation capabilities.
6. Test the Email Send: Click “Execute Workflow” (from the manual trigger) to run the entire flow. Check your recipient’s inbox (and spam folder) to verify the personalized email was sent correctly.

Step 7: Automating Status Updates in Google Sheets

To prevent sending duplicate emails to the same recipient, it’s crucial to update your Google Sheet with the new “Sent” status.

1. Add Another Google Sheets Node: Click the “+” icon after your Gmail node. Add another “Google Sheets” node.

   • Configure Action: Set the “Operation” to “Update Many” or “Update Rows.”
2. Use Existing Credentials: Select the same Google OAuth credential.

3. Configure Sheet Details:

   • Spreadsheet ID: Select your Google Sheet.
   • Sheet Name: Select the relevant sheet.

4. Define Match Criteria:

   • Column to Match: Select “Email.” This tells Netn to find the row where the email address matches.
   • Column Value to Match: Use an expression to pull the recipient’s email from the AI’s output: {{ $json["destination_email"] }}

5. Define Columns to Update:

   • Column Name: Select “Status.”
   • Column Value: Use an expression to set the new status: {{ $json["delivery_status"] }} (which the AI was prompted to set as “terkirim”).
6. Test the Update: Execute the workflow. Check your Google Sheet to confirm that the “Status” column for the sent emails has been updated to “terkirim.”

Step 8: Implementing Smart Logic with the If Node

To ensure your workflow only processes emails that haven’t been sent yet, we’ll add an “If” node at the beginning.

1. Add an If Node: Click the “+” icon after your initial Google Sheets (Get Rows) node but before the Basic LLM Chain node. Add an “If” node.

2. Configure the Condition:

   • Value 1: Use an expression to get the “Status” from the Google Sheets node: {{ $json["Status"] }}
   • Condition: Select “is equal to.”
   • Value 2: Type "belum terkirim" (meaning “not sent” in Indonesian, as per the webinar context).
   • Output: The “If” node will have two branches: “True” and “False.”

3. Connect Branches:

   • Connect the “True” branch of the “If” node to the Basic LLM Chain node. This means if the status is “belum terkirim,” the workflow continues to AI processing.
   • The “False” branch can simply terminate, or you could add a “NoOp” node to explicitly end that path. This ensures that already “terkirim” (sent) emails are skipped.

Step 9: Activating and Refining Your Workflow

1. Thorough Testing: Execute your workflow multiple times with different data scenarios (some “belum terkirim,” some “terkirim”) to ensure every step functions as expected.
2. Activate the Workflow: Once confident, toggle the “Active” switch (usually in the top right of the Netn interface) to enable your Automated personalized email Netn workflow to run automatically based on its trigger (though for the manual trigger, you’ll still click “Execute Workflow”). If you were using a time-based or Google Sheets “On Row Updated” trigger, activating it would make it truly automatic.

3. Continuous Improvement:

   • Prompt Engineering: Continuously refine your AI prompts to improve email quality, tone, and specific calls to action. Experiment with different instructions for the system message.
   • Error Handling: For robust workflows, consider adding error handling nodes (e.g., “Error Workflow” or “Send Email” on error) to notify you if something goes wrong.

Advanced Considerations & Q&A Insights

The webinar covered several insightful questions that highlight the power and flexibility of Netn:

• Trusting AI Responses: The quality of AI-generated content is directly tied to “prompt engineering.” Your prompts define the AI’s persona, tone, and specific instructions. Thorough testing with various data inputs is essential before deploying to real clients. Consistent prompting ensures consistent output.
• Integrating Unsupported Services (HTTP Request Node): For services not natively supported by Netn (like Google Maps or custom email servers accessed via cPanel), the “HTTP Request” node is your go-to. This allows you to interact with any API by sending custom HTTP requests (GET, POST, etc.). This is an advanced topic that often requires understanding API documentation, authentication (e.g., API keys, OAuth), and JSON body construction.
• Workflow Migration: You can easily download your Netn workflow as a .json file and import it into another Netn instance (e.g., from local to cloud, or sharing with colleagues). This ensures portability and backup.

• Automated Triggers (Google Form/Sheets): Instead of a manual trigger, you can set a “Google Sheets Trigger” (e.g., “On Row Added or Updated”). If you connect a Google Form to a Google Sheet, every new submission will automatically add a row to the sheet, which can then trigger your Automated personalized email Netn workflow to send personalized emails without any manual intervention. You can configure this trigger to run every minute, hour, or day.

• Timer/Wait Node: Netn includes a “Wait” node that allows you to pause a workflow for a specified duration (seconds, minutes, hours, days) before proceeding. This is useful for drip campaigns or spacing out email sends.

• If vs. Switch Nodes:

  • If Node: Used for binary conditional logic (True/False). It takes one or more conditions and outputs to one of two branches. You can combine conditions using AND/OR logic.
  • Switch Node: Used for multi-path conditional logic. It evaluates a single parameter and directs the workflow to different branches based on discrete values (e.g., if value is “1” go here, if “2” go there, if “3” go somewhere else). It’s more about “choosing a path” rather than a simple true/false decision.
• Data Security with AI: When connecting to external AI services like OpenAI, you are entrusting your data to their infrastructure. While these companies have robust security measures, it’s a trade-off. For highly sensitive data, self-hosting large language models locally is an option, but it requires significant computing resources (powerful GPUs, ample RAM) far beyond typical consumer hardware.
