Node.js Send an email with Zoho SMTP

In this post, you will learn how to send emails using the Zoho SMTP server using node.js.

We gonna use zeptomail npm module to send emails using Zoho STMP servers. So let’s install it first. Using the npm install command.

$ npm install zeptomail

Here is the pakcage.json

{
  "type": "module",
  "dependencies": {
    "zeptomail": "^3.0.3"
  }
}

Now create a file called sendEmailWithzoho.js with the below code and don’t forget to update the token (see the steps below to generate), to address from address and bounce_address.

        // https://www.npmjs.com/package/zeptomail

        // For ES6
        import { SendMailClient } from "zeptomail";

        // For CommonJS
        // var { SendMailClient } = require("zeptomail");

        const url = "api.zeptomail.com/";
        const token = "Zoho-enczapikey xxxxxxxxxxxxxx";
        
        let client = new SendMailClient({url, token});
        
        client.sendMail({
            "bounce_address": "[email protected]",
            "from": 
            {
                "address": "[email protected]",
                "name": "noreply"
            },
            "to": 
            [
                {
                "email_address": 
                    {
                        "address": "[email protected]",
                        "name": "Arjun"
                    }
                }
            ],
            "subject": "Test Email",
            "htmlbody": "<div><b> Test email sent successfully.</b></div>",
        }).then((resp) => console.log("success")).catch((error) => console.log("error"));
        
            

Now run your script and If everything goes well you should get an email similar to below in your inbox.

$ node sendEmailWithzoho.js
