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.
