The SocketLabs Email Delivery Node.js library allows you to easily send any type of email message supported by our Injection API, from a simple message to a single recipient, to a complex bulk message sent to multiple recipients.

Send Bulk Email Without Having to Build & Maintain Your Own SMTP Email Servers

Basic Message

A basic message is an email message like you’d send from a personal email client such as Outlook. A basic message can have many recipients, including multiple, To Addresses, CC Addresses, and even BCC Addresses. You can also send a file attachment in a basic message.

const {SocketLabsClient} = require('@socketlabs/email');

const client = new SocketLabsClient(parseInt(process.env.SOCKETLABS_SERVER_ID), process.env.SOCKETLABS_INJECTION_API_KEY);

const message = {
    to: "[email protected]",
    from: "[email protected]",
    subject: "Hello from Node.js",
    textBody: "This message was sent using the SocketLabs Node.js library!",
    htmlBody: "<html>This message was sent using the SocketLabs Node.js library!</html>",
    messageType: 'basic'



Bulk Message

A bulk message usually contains a single recipient per message and is generally used to send the same content to many recipients, optionally customizing the message via the use of MergeData.

const {SocketLabsClient, BulkMessage, BulkRecipient} = require('@socketlabs/email');

const client = new SocketLabsClient(parseInt(process.env.SOCKETLABS_SERVER_ID), process.env.SOCKETLABS_INJECTION_API_KEY);

let bulkMessage = new BulkMessage();

bulkMessage.textBody = "Is your favorite color still %%FavoriteColor%%?";
bulkMessage.htmlBody = "<html>Is your favorite color still %%FavoriteColor%%?";
bulkMessage.Subject = "Sending a Bulk Message With Merge Fields";
bulkMessage.From.Email = "[email protected]";

//Use built-in classes and helper methods
let recipient1 = new BulkRecipient("[email protected]");
recipient1.addMergeData("FavoriteColor", "Green");;

//Use object literals
const recipient2 = { 
    emailAddress: "[email protected]",  
    friendlyName: "Recipient #2",
    mergeData: [
        { key: "FavoriteColor", value: "Orange" }
