Dave -- ...and then Dave G said... % % PHP Gurus, % I currently run a few newsletters that go out to small groups of % 50 to 100 people. I use a while loop to send out the emails. I chose a ... % about 50 people. I'm not sure exactly, but maybe ten seconds, possibly % as high as twenty. % Soon I will be creating a script to send out an email to 500 ... % So my question is, is there a way more efficient than while % loops to send out multiple emails with personalized information? Is it % the mail() command that takes time, or the mysql_fetch_array(), or both? % Any suggestions would be greatly appreciated.
0) That really should be $member['name'] and $member['email'] instead of bare indices, you know :-) 1) It's definitely the mail() command, and that's dependent on the underlying mail system. 2) Driving this from the browser is probably a bad way to go because you will always be fighting timeout issues *and* what about a broken connection not because of a timeout? 3) If you want full personalization, you're stuck with individual emails, but lots of mailing list software out there can handle VERPing and, say, footers and save you a whopping lot of work. 4) I did some work this summer on a mass mail script; with a little script tweaking and some (but not onerous) qmail tweaking, I got our times down to around 100ms per email. That puts us sending about 30k [personalized] emails per hour, which is an order of magnitude faster than the speed of the guys who lost the contract to us :-) It's discussed on the list a bit; check the archives.
