What is the most efficient way to confirm the participation of a guest speaker while away from your desk?

Downloading the Gmail mobile app on your smartphone is the most efficient way to confirm the participation of a guest speaker while away from your desk because it provides you with immediate access to your email account. This allows you to check for any recent correspondence and respond directly to the speaker in real time, ensuring clear and direct communication. The app's notifications also help you stay updated on any incoming messages related to the event.

Using a school phone to call may not be efficient if you’re away from your desk or if the school phone is not easily accessible. Sending a text to the speaker might not be suitable if you don’t have their phone number or if the speaker does not prefer that mode of communication. Asking a colleague to check your email could delay the process, as it relies on another person’s availability and might result in miscommunication or oversight. Overall, utilizing the Gmail mobile app allows for a more personal and prompt approach to confirming the guest speaker's participation.
