In PHP, how can the use of tools like Supermailer help in efficiently sending bulk emails while ensuring compliance with provider restrictions?

Sending bulk emails can be challenging due to provider restrictions on the number of emails that can be sent per hour or per day. Tools like Supermailer can help in efficiently sending bulk emails by managing the sending process, scheduling emails to comply with provider restrictions, and providing detailed delivery reports.

// Example PHP code using Supermailer to send bulk emails efficiently

// Include Supermailer library
require_once('supermailer.php');

// Initialize Supermailer
$supermailer = new Supermailer();

// Set provider restrictions (e.g. maximum emails per hour)
$supermailer->setProviderRestrictions(500, 'hour');

// Add recipients and email content
$supermailer->addRecipient('recipient1@example.com', 'Recipient 1');
$supermailer->addRecipient('recipient2@example.com', 'Recipient 2');
$supermailer->setSubject('Your subject here');
$supermailer->setBody('Your email content here');

// Send bulk emails
$supermailer->sendBulkEmails();
