php - Trying to use PHPMailer to send mass-emails

one text

Solution:

Take a look at the mailing list example provided with PHPMailer - you could probably improve the efficiency of what you're doing so far. I'd also recommend making your script less monolithic - break it up into small pieces that link together and you should find it easier to work with.

I think your immediate problem is simply this:

return $email->Send();

That will send the first email, then quit! Just delete the return (and maybe add some error handling as per the example) and the loop will be able to continue.
