What must the contractor specify when using email for notifications?

When using email for notifications, the requirement for the sender to specify a receipt notice is crucial. This is because a receipt notice serves as confirmation that the email has been received by the intended recipient. It establishes a clear line of communication, providing assurance that important information or notifications have been acknowledged, which is particularly important in contractual contexts where timely responses and communication can impact project timelines and responsibilities.

While sending emails during business hours or requiring CCs to third parties may seem like good practices, they are not necessarily mandated for contractual notifications. Similarly, while encryption enhances security, it is not universally required for all email communications unless specified by the terms of the agreement. The focus on receipt notices directly relates to the need for accountability and documentation in communication between parties in a contractor agreement.
