Auto Email Sender

This package is ideal for bulk email sending where email content is dynamic and personalized for each recipient.

Easy-to-use API with minimal configuration required.

Installation

Install the package via npm:

npm install auto-email-sender

Usage

Here’s how you can use the auto-email-sender package in your Node.js project:

Step 1: Prepare Your Excel File

Ensure your Excel file contains the following columns:

Email (the recipient's email address)
Name (the recipient's name)
Other columns (optional data to be included in the email)

Example Excel structure:

| Email | Name | Data1 | Data2 | |---------------------|-----------|-------|-------| | [email protected] | Aniket Subudhi | Info1 | Info2 | | [email protected] | Swagat | Info3 | Info4 |

Step 2: Create an HTML Template

Create an HTML file for the email content. Use placeholders in the form of {{placeholder_name}} for dynamic content.

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Email Template</title>
    <style>
        body {
            font-family: Arial, sans-serif;
            background-color: #f4f4f4;
            color: #333;
            margin: 0;
            padding: 20px;
        }
        .container {
            background-color: #fff;
            padding: 20px;
            border-radius: 5px;
            box-shadow: 0 0 10px rgba(0,0,0,0.1);
        }
        .header {
            font-size: 24px;
            font-weight: bold;
        }
        .content {
            margin-top: 10px;
        }
    </style>
</head>
<body>
    <div class="container">
        <div class="header">Hello {{name}},</div>
        <div class="content">
            This is a dynamic email message.<br>
            Here is some additional data: {{other1}}, {{other2}}.
        </div>
    </div>
</body>
</html>

Step 3: Use the Package in Your Project

Here’s an example of how to use the package:

const AutoEmailSender = require('auto-email-sender');

// SMTP configuration
const smtpConfig = {
    host: 'smtp.example.com',
    port: 587,
    secure: false, // true for 465, false for other ports
    auth: {
        user: '[email protected]',
        pass: 'your-email-password',
    },
};

// Initialize the AutoEmailSender with the Excel file, SMTP config, and column names
const emailSender = new AutoEmailSender('path/to/your/excel/file.xlsx', smtpConfig, 'Email', 'Name');

// Set the subject and path to the HTML template
const subject = 'Your Email Subject';
const templatePath = 'path/to/email_template.html';

// Send emails for all rows in the specified columns
emailSender.sendEmailsForColumn(subject, templatePath);

Step 4: Run Your Script

To send the emails, simply run your Node.js script:

node your_script.js
