I've used the program for mailing of about 1000 for about a year and it does exactly what I need to to do. I highly recommend using this program. I handles HTML email, server STMP spam protection with a throttle, on the fly email editing, drop scheduling and more. I'm on the west coast and set up my emails in zip string to start in the East at about 6am here, 9am in the East. About the time most of my prospects have cleared their overnight email of junk! Great Job!
