Possible Duplicate:
How to send 100.000 emails weekly?

I’m tweaking a registration system for internal use at a large organization. It needs to send out daily reminders to users who are registered for events each day. This system started out small but now some days there are 300 – 600 people registered for an event.

So far I’ve been using php’s mail function and that has worked fine. However, they are using Google Apps for their e-mail and it would be nice to send from a dedicated account and reference the sent mail folder if we need to look at what was sent out.

My thoughts so far:

  1. I’ve tested PHPMailer and it works fine with Google Apps but I don’t believe it batches e-mails – so I think it would have to open and close the SMTP connection for each e-mail which might be inefficient.

  2. I know I can edit the php.ini file and specify SMTP information to be Google Apps – that might be an option as well – but from what I understand PHP’s mail function is not really the best way to send large numbers of e-mails either.

  3. Years ago I looked at PEAR::Mail which I believe does a much better job at sending large numbers of e-mails, but I wasn’t sold on it then. Maybe it is the best solution but I was wondering if something more recent or more awesome was out there.

So, are the best ways to send up to a few hundred e-mails each day via G-Mail from PHP?

    You could use SwiftMailer.

    Easy to set up for use with Gmails servers. You can do batch send as well.

    I’ve used it a lot for sending mass emails, it works well.
