When is electronic information considered received by the addressee?

The best choice is that electronic information is considered received by the addressee if it is processed by the addressee's information system. This concept aligns with the legal perspective on electronic communications, which recognizes that receipt is contingent upon the information successfully navigating the addressee's technological framework.

In this scenario, "processed by the addressee's information system" underscores that the information has not only arrived in the inbox but has also been recognized and cataloged by their system, making it accessible and actionable for the recipient. This processing is critical as it signifies that the recipient can now engage with the information contained in the communication, fulfilling the necessary conditions for "receipt" in a legal context.

Other options, such as when the message enters the email inbox or when it is printed out and reviewed, do not take into account the necessary functionality of the addressee’s information system. Acknowledgment of receipt also emphasizes a separate act on the part of the recipient, which may not conclusively indicate that the information was received in a legal sense until it has been processed. Therefore, the understanding of "receipt" goes beyond mere arrival and hinges upon the interaction with the system that allows the addressee to access and respond to the information.
