Of course, every message sends a message, even a barebones OOO that seems to say nothing more than that you’re away until next week, so why not try to inject a little personality? You could get quirky by giving your auto-responder robot a personality. You could dispense with words altogether and substitute a gif or emojis. Or how about a little retro concrete poetry – you know, where you arrange your words on the screen to form an image of a palm tree or a pina colada? It might be worth noting here that the amount of personality you inject depends on your trade. What earns you cachet in the creative industries might backfire in the financial sector, for instance.
Over time, I began to suspect that those who might be telling the truth (of which I suspected there were very few), would mention their relationship to the person and possibly the cause, for example “My grandmother just passed away after surgery.” The ones who left it wide open (“someone close has recently died”) led me to imagine that it could be a random person in their city that they read about in the news, their goldfish, or perhaps a distant relative who had passed away in the previous few years.

Informal approach helps your clients think of you as of a human being. This alleviates some of the annoyance they may feel because of not receiving a proper reply. Generally, making people laugh is a great way to make people remember you. Do that and your clients won’t switch to a competitor.
