I have a couple questions on large scale mass emailing.
It can get a bit technical, so didn't want to post my babble unless this is the right audience.
I'm currently doing about 1 - 1.5 mil emails per day on average.
Tried contacting Habeas/Returnpath, but can't get a response. I assume because they see my volume but since I'm not a web host or 'famous' autoresponder service they might be thinking 'spam'. Can't blame them, but no, its actually the exact opposite.
