Patent 9306895 was granted and assigned to Amazon on April, 2016 by the United States Patent and Trademark Office.
Technologies are described herein for predicting and resolving message deliverability events. A message deliverability event is an event initiated by a mailbox provider that results in the refusal of the mailbox provider to deliver a message to the inbox of its intended recipient, or that results in a mailbox provider delaying the delivery of a message to the inbox of its intended recipient. The transmission of messages to mailbox providers and responses to the transmission of the messages can be monitored. Based upon the monitoring, a determination can be made as to whether the probability of a future message deliverability event exceeds a threshold with regard to one or mailbox providers. If there the probability of a message deliverability event exceeds the threshold, one or more actions may be taken to reduce the probability that the future message delivery event will occur.
