What is the most efficient action to take if you are expecting an important email while away from your desk?

Using the Gmail mobile app on your smartphone is the most efficient action for staying connected to your important emails while away from your desk. The mobile app is designed to provide full access to your email account, allowing you to not only receive notifications of incoming messages but also to read, respond, and manage your emails directly from your device. This ensures that you remain updated in real-time, without the need to rely on external devices or other people.

Checking your email from a friend's computer may not be as efficient, as it depends on having access to another device and does not offer the convenience of instant notifications that the mobile app provides. Asking a colleague to check your email could lead to miscommunication or delay, as you are relying on someone else to manage the situation for you. Sending a text message to a guest speaker does not directly address the need to monitor your email and is unlikely to provide the information you are waiting for. Therefore, the mobile app stands out as the most practical solution for immediate access and responsiveness.
