Re: newbie question: duplicate emails

The best way is to use an email list manager. I remember someone suggesting one, but I've totally forgotten it now. Personally the way I would do it is take the first list and load all the email addys into the Bcc field. Or break them up into small chunks of less than 50 at a time, since trying to pop out an email with 1000 recipients will get you flagged as spamming (which is at least an inconvenience to have to talk with your admin) and could cause SMTP to choke. But less than 50 at a time shouldn't do any harm. Then finish up with all the emails in that list, then go to another function to spit another round. So I'd set up the function to take the ID of the list to email, which would email all the users as mentioned above. I'd have the function in a loop which checks how many lists there are, then feeds them one at a time to the function. Easy to alter later, and it's a weensy bit easier to debug. -- Plutarck Should be working on something... ...but forgot what it was.
