✉️ easy-mailer

A lightweight and developer-friendly email SDK for Node.js that simplifies sending emails with zero-config setup, bulk sending, and prebuilt templates like OTP and welcome emails.

🚀 Features

• ⚡ Simple & clean API
• 📤 Bulk email sending with concurrency control
• 🎨 Prebuilt templates (OTP, Welcome)
• 🔁 Retry mechanism with backoff
• ⏱️ Rate limiting to prevent spam blocking
• 🌐 Multi-provider support (Gmail, SMTP)
• 🔐 Secure usage with environment variables

📦 Installation

npm install @graminpoly123/easy-mailer

⚙️ Setup

import mailer from "@graminpoly123/easy-mailer";

mailer.init({
  provider: "gmail",
  user: process.env.EMAIL_USER,
  pass: process.env.EMAIL_PASS,
});

✉️ Send a Simple Email

await mailer.send({
  to: "[email protected]",
  subject: "Hello 🚀",
  text: "This is a test email",
});

🔢 Send OTP Email

await mailer.sendOTP({
  to: "[email protected]",
  code: 123456,
});

📤 Bulk Email Sending

await mailer.bulkSend({
  to: ["[email protected]", "[email protected]"],
  subject: "Bulk Email 🚀",
  template: "welcome",
  data: { name: "User" },
  concurrency: 2,
});

🎨 Using Templates

await mailer.send({
  to: "[email protected]",
  subject: "Welcome",
  template: "welcome",
  data: { name: "Nikhil" },
});

🌐 SMTP Provider Example

mailer.init({
  provider: "smtp",
  host: "smtp.yourserver.com",
  port: 587,
  user: "your-email",
  pass: "your-password",
});

🔐 Environment Variables (Recommended)

Create .env.local:

[email protected]
EMAIL_PASS=your_app_password

⚠️ Important Notes

• Use Gmail App Password, not your normal password
• This package works only on backend (Node.js)
• Do not expose credentials on frontend

🧠 How It Works

• Uses a provider system (Gmail / SMTP)
• Handles bulk emails with concurrency + rate limiting
• Retries failed emails automatically
• Supports dynamic templates

⚡ Quick Demo

import mailer from "@graminpoly123/easy-mailer";

mailer.init({
  user: process.env.EMAIL,
  pass: process.env.PASS,
});

await mailer.sendOTP({
  to: "[email protected]",
  code: 123456,
});
