Systems and methods for controlling electronic message transmissions

Abstract:

Methods and systems for controlling electronic message transmission are described. An example method may include: receiving, via a network, an error report generated based on a response from a recipient email server responsive to an attempt to send a message to an email address associated with the recipient email server, the error report indicating that the attempt to send the message was rejected by the recipient email server; adding the email address to a block list, wherein any subsequent attempt to send messages to the email address is blocked based on the email address being in the block list; and removing the email address from the block list after a defined period of time.
