    console.error('Error:', err);
  } else {
    console.log('Email message:', message.toString());
  }
});

HTML Email Composition

This feature allows you to compose an email with HTML content, which can include rich text formatting and images.

const MailComposer = require('mailcomposer');
const mail = new MailComposer({
  from: '[e-mail]',
  to: '[e-mail]',
  subject: 'Hello',
  html: '<h1>Hello world!</h1>'
});
mail.build((err, message) => {

    console.error('Error:', err);
  } else {
    console.log('Email message:', message.toString());
  }
