I need a very robust and efficient email system for a mailing list of 3500+ blog subscribers who were converted from an e-newsletter list. (I'm not sending spam, all were double opt in.)
I've tried WordPress Email Notification Plugin v2.3.1 and it nearly kills the server when it's running. And it takes a few hours to send all of the emails.
I've tried to install Subscribe2 and the install didn't work. So I thought I'd look for some suggestions before I invest the effort to make it work, only to find it lacking.
How does anyone run a blog email platform with several thousand emails? What if I double or triple the count?
All suggestions are welcome,
