🛠 When to Use Nodemailer

Nodemailer is great when:

• You need a simple and lightweight solution
• You already have a working SMTP server
• You don’t need tracking, templates, or contact management
• You prefer full control and want to build everything yourself

Example: Send Email with Nodemailer

import nodemailer from 'nodemailer';

const transporter = nodemailer.createTransport({
  host: 'smtp.your-email.com',
  port: 587,
  auth: {
    user: 'username',
    pass: 'password',
  },
});

await transporter.sendMail({
  from: '[e-mail]',
  to: '[e-mail]',
  subject: '🚀 Welcome!',
  html: '<h1>Hello!</h1><p>Thanks for signing up.</p>',
});
