Email Logging and Tracking

If you need to track email opens or clicks, integrate with an email tracking service or use webhooks. Services like Mailgun or SendGrid provide these features.

Example with Mailgun:

const mailgun = require('mailgun-js');
const mg = mailgun({ apiKey: process.env.MAILGUN_API_KEY, domain: process.env.MAILGUN_DOMAIN });

const data = {
    from: 'Your Name <[email protected]>',
    to: '[email protected]',
    subject: 'Hello',
    text: 'Hello world!'
};

mg.messages().send(data, (error, body) => {
    if (error) {
        console.error('Error sending email:', error);
    } else {
        console.log('Email sent successfully:', body);
    }
});
