I have a social like network thingie and we are going to need to send registration and periodic activity notification emails to our members - it wil soon be in the kk's per day going out. All double opt-in with registration of course what I need to know is there methods that we need to go through to make sure that our emails are white listed and get through the spam filters to our users. I asked this same question in another place and just got a bunch of affiliate links to awber and other auto-responders which is most likely not what we need. We would prefer to do all the emails ourself - but need to get pointed in the right direction. Maybe a forum owner could help as well? Thanks
