Are there tools or services available to check how emails are classified in terms of spam by spam filters?

To check how emails are classified in terms of spam by spam filters, you can use email deliverability testing tools or services. These tools will analyze your email content, sender reputation, and other factors to determine how likely your emails are to be marked as spam by various email providers. 

// Example code using a third-party email deliverability testing service
$email = 'example@example.com';
$subject = 'Test email subject';
$message = 'This is a test email message';

$url = 'https://api.emaildeliverability.com/check-spam';
$data = array(
    'email' => $email,
    'subject' => $subject,
    'message' => $message
);

$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data)
    )
);

$context  = stream_context_create($options);
$response = file_get_contents($url, false, $context);
$result = json_decode($response);

if ($result->spam_score > 0.5) {
    echo 'This email is likely to be classified as spam.';
} else {
    echo 'This email is not likely to be classified as spam.';
}
