I need a basic emailer system that would live on its own VPS that enables me to setup bulk email lists, could be up to 50K for some lists, so I can automate emails out to them. GUI front end so I can load the list via csv or excel files.
Need to be able to send emails to a big list ( up to 50000) , and it needs to be fast. Must not do anything illegal as it cannot get banned etc.
Must have ability for end user to click a link and automatically remove them self from the list.
Probably some wordpress or similar system out there that can do this but I don't have the time to research.
As it will live on its own VPS, it will need to have it's own mail system setup etc as it will not be using external mail systems to send out mail.
