DoubleClick reported that the last quarter of 2004 saw the highest ever orders-per-opened-email (0.35 percent), despite seeing lower email open rates. That represents a 14 percent rise over the same period the year before. DoubleClick noted that more and more email applications fail to load graphics when people open their messages, making it difficult to track the real open rates. Click-to-purchase conversions came in just shy of tying record levels, rising to 4.8 percent.
