If someone is late on getting something to you for a somewhat inexcusable reason, do you prefer something to the effect of:
I apologize for the delay in my response. [Insert response]
I apologize for the delay in my response. Unfortunately, we had an e-mail snafu on our side that caused a delay in [insert task]’s completion. [Insert response]?
As for me, I prefer the former, especially if I’m making the apology to a customer. I see the latter as making excuses. I also see the latter as wasting the reader’s time with something they don’t really care about…the point is that the response is there and that it is (unfortunately) late. However, I’m wondering if the latter makes the apology seem more or less real. I would argue that it seems less real, because it’s like “I apologize but I couldn’t do anything about it anyways.”
