Im slowlllllllly getting CE to work well for me (+ROI is close). What I like about them is the ability to earn from the upsells and dialer revenue.
A lot of these 4free programs are having a hell of a time getting mail into AOL, Hotmail and Yahoo which makes a huge difference in conversions as a lot of people like to use those addresses.
A company pro-active like CE cash is making sure email gets through is very important.
