On Delay in Replying?

If you're apologizing for the late response, make sure you lead by acknowledging your response is late. A simple, "Apologies for the delayed response–" or, "Sorry for not getting back to you sooner–" does the trick. Keep the apology to one sentence in most cases. It doesn't need to be your whole email.

What is delay in response?

Many physiological processes have a delay before they begin to respond to a stimulus. Such physiological delays are termed reaction time, or response latency, or simply response delay. In these processes, there is a period of time between the onset of the stimulus and the beginning of the response.

How do you write an apology email for late reply?

First of all, I want to apologize for my delay in replying to your request. Thank you for thinking of me for the opportunity, but unfortunately I won't be able to participate this time around. My workload has been particularly heavy, and I don't have much extra time right now. But I'll let you know if anything changes.
