Mailer

Mailer is a Node.js application for sending bulk emails using Nodemailer, CSV parsing, and HTML templates. This script reads recipient data from a CSV file, manages email attachments, and tracks sent emails to avoid duplication. Here's an overview of its functionality and setup:

Features

• Bulk Email Sending: Send emails in bulk to recipients listed in a CSV file.
• Attachment Support: Include attachments dynamically from a specified directory.
• Template-based Emails: Use HTML templates for composing emails with dynamic content.
• Email Tracking: Keeps track of sent emails to prevent sending duplicates.
• Delay Between Emails: Configurable delay between each email to comply with email service provider limits.

Installation

To use the Mailer script, follow these steps:

1. Clone the Repository:

   git clone https://github.com/Fedot-Compot/mailer.git
   cd mailer

2. Install Dependencies:

   npm install

3. Set Up Environment Variables:

   Create a .env file in the root directory of the project and add the following environment variables:

   [email protected]
   PASSWORD=your_email_password
   SENDER_NAME=Your Name
   MAX_EMAILS=100  # Number of maximum emails to send
   WAIT_BETWEEN_MAILS=5  # Wait time in seconds between each email
   

   Ensure subject.txt and template.html files are placed in the data/ directory. Attachments should also be placed in data/attachments/ directory.

4. Run the Script:

   node index.js

   This will start sending emails to recipients listed in data/recipients.csv.

Configuration

• SMTP Configuration: Modify the transporter object in index.js to match your SMTP server settings (e.g., host, port, secure mode).
• Email Content: Customize subject.txt and template.html (for base64 you can use this website) to tailor the subject and body of your emails.

Notes

• Ensure Node.js and npm are installed on your system before running the script.
• Handle sensitive information like email credentials securely using environment variables.
• Adjust MAX_EMAILS and WAIT_BETWEEN_MAILS according to your email service provider's sending limits and policies.
