Managing Template Variables

Template variables allow you to personalize your emails with dynamic content. This guide covers everything you need to know about using variables in your templates.

Variable Syntax

Basic Usage

Variables use the {variable_name} syntax:

<h1>Hello, {first_name}!</h1>
<p>Your order #{order_id} has shipped.</p>

Naming Conventions

  • Use lowercase letters
  • Separate words with underscores
  • Keep names descriptive and concise
  • Avoid special characters

Good examples:

  • {customer_name}
  • {order_total}
  • {shipping_address}

Variable Types

Subject Line

First of all, yes, you can use variables in the subject line of your email.

Hi, {first_name}!

Text Variables

Basic string replacement in text blocks:

Dear {customer_name},
Your order #{order_id} has shipped.

URL Variables

Links and images:

Image URL

{product_image_url}

Image Alt Text

{product_image_alt_text}

The Social Media block can also take dynamic variables.

Twitter/x

{twitter_url}

Instagram

{instagram_url}

Passing Variables to Templates

When you send an email using Notify, dynamic variables in your template (like {name} or {company}) need values. Notify makes this simple:

  1. Sending from the Notify Website Pick a saved template, and Notify automatically prompts you to fill in required variables before sending. No API calls, no extra setup — just fill in the values and hit send.

  2. Sending via the Notify NPM Package or API

Pass variable values in the request body when sending an email from your backend. Works with both the Notify SDK and direct API calls.

Example: Sending an Email with Variables

Using the Notify NPM Package

First, install the Notify NPM package:

npm install notifycx

Then, use the following code to send an email with variables:

import Notify from "notifycx";

const notify = new Notify("<your_api_key>");

async function sendTemplatedEmail() {
  try {
    const response = await notify.sendEmailFromTemplate({
      to: "recipient@example.com",
      from: "noreply@notify.cx",
      templateId: "<your_template_id>",
      variables: {
        name: "John Doe",
        company: "Example Inc.",
      },
    });

    if (response.error) {
      console.error("Error sending template email:", response.error);
      return;
    }

    console.log("Template email sent successfully:", response.data);
  } catch (error) {
    console.error("Failed to send template email:", error);
  }
}

sendTemplatedEmail();

Using the Notify API

If you’re not using the SDK, send emails via a simple HTTP request:

async function sendEmailFromTemplate(params: SendEmailFromTemplateParams): Promise<void> {
  const response = await fetch(`https://notify.cx/api/public/v1/send-email-from-template`, {
    method: "POST",
    headers: {
      "Content-Type": "application/json",
      "x-api-key": this.apiKey,
    },
    body: JSON.stringify(params),
  });

  if (!response.ok) {
    throw new Error(`Failed to send email from template: ${response.statusText}`);
  }
  console.log("Email from template sent successfully:", await response.json());
}

No need to overthink email handling — pick a template, pass some data, and Notify does the rest.
