I appreciate this is not what UE is designed for, I just wondered if anyone had found a way to "throttle" the number of emails sent by editing / adding PhP scripts. I've kinda got so used to using webassist products I always try to use them before looking elsewhere.
I'll take a look around the web for a newsletter manager type program, I doubt I'll have a problem (fingers crossed) with blacklisting as the mail is aimed at my clients actual customer list, I'm assured it's all opt in and above board. As I'm typing this I'm thinking it might be an idea to do more research on this before agreeing to take over the site ;)
Thanks for the warning.
