What methods can be used to track which emails were successfully sent to valid addresses from a MySQL database using PHP?

To track which emails were successfully sent to valid addresses from a MySQL database using PHP, you can create a column in your database table to store the status of each email (e.g., 'sent' or 'failed'). After sending each email, update the status in the database accordingly. You can also log any errors or bounce-back emails to further track the success of each send. 

// Connect to MySQL database
$mysqli = new mysqli("localhost", "username", "password", "database");

// Update email status to 'sent' after successful send
$emailId = 123; // ID of the email record
$mysqli->query("UPDATE emails SET status = 'sent' WHERE id = $emailId");

// Log any errors or bounce-back emails
$error = "Error message here";
$mysqli->query("INSERT INTO email_logs (email_id, error_message) VALUES ($emailId, '$error')");

// Close database connection
$mysqli->close();
