Right now I am in search of finding a good script that can send out mass emails. It is for my forum so not it isn’t for spam more of newsletters that will let me do it with a cron job rather than a whole bunch at once. So doing it through a mail list will be appropriate since I can put intervals between a certain set of mails.
I usually use the script provided by vbulletin but it gives me errors after an email has been sent out which is annoying and unruly. Hopefully I can’t find one soon and if it is good, you can expect a recommendation from me here.
