Required Access Level: SendHttp

What's a bulk email?

When using Elastic Email you send emails to your contacts. One of options is to send bulk emails. Bulk email can be described as a single email message send to a large group at once.

Preparation

It's NodeJS code, so make sure you have it installed or download it here: https://nodejs.org/en/download/

Create a new JavaScript file snippet.js and open it in editor of your preference eg. Visual Studio Code (https://code.visualstudio.com/)

Let's dig into the code

Put the below code to your file.

Load library using below line:

const ElasticEmail = require('@elasticemail/elasticemail-client');

Get client instance:

const client = ElasticEmail.ApiClient.instance;

Generate and use your API key (remember to check a required access level):

const apikey = client.authentications['apikey'];
apikey.apiKey = "YOUR_API_KEY";

Create an instance of EmailsApi that will be used to send a bulk email.

const emailsApi = new ElasticEmail.EmailsApi();

First you need to specify email details:

• email recipients:
  • this example demostrates merge fields usage, for each recipient {name} will be changed to recipient's name
• email content:
  • body parts – in HTML, PlainText or in both
  • from email – it needs to be your validated email address
  • email subject

Find out more by checking our API's documentation: https://elasticemail.com/developers/api-documentation/rest-api#operation/emailsPost

const emailData = {
    Recipients: [
        {
            Email: "johnsmith@domain.com",
            Fields: {
                name: "John"
            }
        }
    ],
    Content: {
        Body: [
            {
                ContentType: "HTML",
                Charset: "utf-8",
                Content: "<strong>Hi {name}!<strong>"
            },
            {
                ContentType: "PlainText",
                Charset: "utf-8",
                Content: "Hi {name}!"
            }
        ],
        From: "myemail@domain.com",
        Subject: "Example email"
    }
};

Create a callback function that will be called when response comes back.

In case of error it will display error details, otherwise it will display a success messages.

const callback = (error, data, response) => {
    if (error) {
        console.error(error);
    } else {
        console.log('API called successfully.');
        console.log('Email sent.');
    }
};

And finally, call emailsPost method from the API to send an email:

emailsApi.emailsPost(emailData, callback);

The whole code to copy and paste:

const ElasticEmail = require('@elasticemail/elasticemail-client');

const client = ElasticEmail.ApiClient.instance;

const apikey = client.authentications['apikey'];
apikey.apiKey = "YOUR_API_KEY";

const emailsApi = new ElasticEmail.EmailsApi();
const emailData = {
    Recipients: [
        {
            Email: "johnsmith@domain.com",
            Fields: {
                name: "John"
            }
        }
    ],
    Content: {
        Body: [
            {
                ContentType: "HTML",
                Charset: "utf-8",
                Content: "<strong>Hi {name}!<strong>"
            },
            {
                ContentType: "PlainText",
                Charset: "utf-8",
                Content: "Hi {name}!"
            }
        ],
        From: "myemail@domain.com",
        Subject: "Example email"
    }
};

const callback = (error, data, response) => {
    if (error) {
        console.error(error);
    } else {
        console.log('API called successfully.');
        console.log('Email sent.');
    }
};
emailsApi.emailsPost(emailData, callback);
