I would like to add the option to mass email all the members on my site. I looked into a bulk email program, but they look lame. I have to export my list and then import it. I figured I could just do it all from my site, but the one thing I liked from the programs was the ability to remove addresses where the email bounces back. Is it possible in PHP to check to see if an email went through or came back? Would I have to log into the email account I used as the send from address to see if I got a response or is there another way?
