Frequently in training, I ask attendees, “how long should you wait before responding to a customer or even a colleague using emails?”. The answer can vary from “one to two hours”, “the next day” to more surprisingly “as quick as you can”.
Interestingly enough, from an email etiquette perspective, the answer is 24 hours or the next day.
Naturally, depending on our job role, the situation we find ourselves or level of urgency needed in a given time we might respond sooner. However, the idea that we need to come back to someone instantly or within the hour is unreasonable and unfair to both parties.
