What best practices should be followed when sending personalized emails to multiple recipients in PHP?

When sending personalized emails to multiple recipients in PHP, it's important to use a loop to iterate through each recipient and customize the email content accordingly. This can be achieved by storing recipient-specific information in an array or database and dynamically inserting it into the email template. Additionally, make sure to properly sanitize and validate user input to prevent security vulnerabilities. 

// Example code snippet for sending personalized emails to multiple recipients in PHP

// Recipient-specific information
$recipients = [
    ['email' => 'recipient1@example.com', 'name' => 'Recipient 1'],
    ['email' => 'recipient2@example.com', 'name' => 'Recipient 2'],
    ['email' => 'recipient3@example.com', 'name' => 'Recipient 3']
];

// Email template
$emailTemplate = "Hello {name},\nThis is a personalized email.";

// Send personalized emails
foreach ($recipients as $recipient) {
    $emailContent = str_replace('{name}', $recipient['name'], $emailTemplate);
    
    // Send email using mail() function or a library like PHPMailer
    // Example: mail($recipient['email'], 'Subject', $emailContent);
}
