Email Notification Node

The Email Notification node sends HTML emails from your workflow, delivering alerts, trade confirmations, and reports straight to your inbox. It supports dynamic content interpolation so every email can include live data from upstream nodes.

Configuration

Template Interpolation

Use curly braces to inject data from upstream nodes into your subject and body. The edge label connecting the previous node to your Email Notification node determines the variable prefix.

Example: Trading Alert Email

Subject:

Trade Alert: {{llm.output}} signal for BTC/USD

Body:

<h1>Trading Signal Detected</h1>

<table style="border-collapse: collapse; width: 100%;">
  <tr>
    <td style="padding: 8px; border: 1px solid #ddd;"><strong>Symbol</strong></td>
    <td style="padding: 8px; border: 1px solid #ddd;">BTC/USD</td>
  </tr>
  <tr>
    <td style="padding: 8px; border: 1px solid #ddd;"><strong>Signal</strong></td>
    <td style="padding: 8px; border: 1px solid #ddd;">{{llm.output}}</td>
  </tr>
  <tr>
    <td style="padding: 8px; border: 1px solid #ddd;"><strong>Current Price</strong></td>
    <td style="padding: 8px; border: 1px solid #ddd;">${{price_data.data.prices[0].current}}</td>
  </tr>
  <tr>
    <td style="padding: 8px; border: 1px solid #ddd;"><strong>24h Change</strong></td>
    <td style="padding: 8px; border: 1px solid #ddd;">{{price_data.data.prices[0].changePercent24h}}%</td>
  </tr>
  <tr>
    <td style="padding: 8px; border: 1px solid #ddd;"><strong>RSI</strong></td>
    <td style="padding: 8px; border: 1px solid #ddd;">{{price_data.data.prices[0].indicators.rsi}}</td>
  </tr>
</table>

<p style="margin-top: 16px; color: #666;">
  This alert was generated by your NickAI workflow.

Example: Order Confirmation Email

Subject:

Order Executed: Bought {{exchange.quantity}} {{exchange.symbol}}

Body:

<h1>Order Confirmation</h1>
<p>Your trade was executed successfully.</p>

<ul>
  <li><strong>Symbol:</strong> {{exchange.symbol}}</li>
  <li><strong>Side:</strong> {{exchange.side}}</li>
  <li><strong>Quantity:</strong> {{exchange.quantity}}</li>
  <li><strong>Order ID:</strong> {{exchange.orderId}}</li>
</ul>

Example Workflow

A typical pattern: fetch market data, analyze it with an LLM, check for a buy signal, and send an email alert.

You can also use the Email Notification node on the false branch to alert yourself that no signal was found, or connect it after any node where you want a status update.

Credentials Setup

You have two options for sending emails:

NickAI Credits (default)

Select NickAI Credits in the credential dropdown. Emails are sent from [email protected] using the platform's Resend account. There is nothing to configure -- it works out of the box.

Your Own Resend API Key

If you want emails to come from your own domain:

1. Create a free account at resend.com ↗.
2. Verify your domain ↗ in the Resend dashboard.
3. Generate an API key at resend.com/api-keys ↗.
4. In NickAI, go to Credentials and add a new Resend credential with your API key.
5. Select your credential in the Email Notification node's dropdown.

When you use your own API key, NickAI automatically detects your first verified domain and sends from [email protected].

Output

After execution, the node produces a result object you can reference in downstream nodes.
