Sending mass emails programmatically

Question

I need to be able to periodically send email alerts to subscribed users. PHP seems to struggle with sending one message, so I'm looking for good alternatives.

Any language will do, if the implementation is fast enough. The amount of mails sent will eventually be in the thousands.

If purchasing licensed software can be avoided, so much the better.

Answer 1

Email queueing in php - the short version - Pear's Mail_Queue. I've been using this to send out 30-50,000+ mails per day or more (a few days a week) without problems for more than a year.

Answer 2

smtplib in python is a doddle to set up and a very clean API.
