Sending mass email using PHP
- by Alan
I am currently writing a music blog. The administrator posts a new article every 2-3 days. Once the administrator posts an article, a mass email will be sent to around 5000 subscribers immediately.
What is the best way to implement the mass mail feature?
Does the following function work?
function massmail()
{
$content = '...';
foreach ($recipients as $r) {
$_content = $content . '<img src="http://xxx/trackOpenRate.php?id='.$r.'">';
mail($r, 'subject', $_content);
}
}
Another question: If all 5000 subscribers are using Yahoo Mail, will Yahoo treat it as a DDOS attack and block the IP address of my SMTP server?
