main thing to think about with any mailing list is what limits does your host have on sending of emails
if your on a shared server make sure you know
you can throttle the amount of mail that marketing manager sends by editing admin/mm_files/mm_mail.pl
Code:
# Pause, as not to hurt the server
if ($i % 3 == 0) {
sleep(1);
}
the standard setup as above will sleep for 1 second after ever third email is sent
set a higher sleep time for a slower (less server load) mail out
On the right server marketing manager will handle mailing lists with 100 s of thousands of emails[/code]
