Claim:
1. One or more non-transitory computer-readable media storing computer-executable instructions that, when executed by one or more processors, instruct the one or more processors to perform acts comprising: transmitting a message to multiple clients associated with multiple user identifiers (IDs), respectively, the message containing a parameter embedded in a link by which a response to the message by any of the multiple clients is trackable to identify which of the multiple clients respond, such that the parameter of the message causes a client computing device to record an operating record with respect to the message; obtaining respective response activity records of particular clients as a subset of the multiple clients in response to the message to determine particular user IDs associated respectively with the subset of particular clients; generating a graylist including one or more user IDs of the respective multiple user IDs, each of the one or more user IDs of the respective multiple user IDs in the graylist being different from each of the particular user IDs and identifying the clients for whom a determination is made that a ratio of a number of times the respective clients did respond to the message to a total number of times the message has been sent is smaller than a threshold value; and transmitting a further message to a portion of the multiple clients associated with multiple user IDs, the further message being associated with an item category corresponding to the graylist, and the portion of the multiple clients including the multiple clients associated with the multiple user IDs except the clients identified in the graylist.
