I’m out of town. I’m looking forward to connecting with you when I return. If you’re getting this note, it means that I’ve received your email. (Thank you!) I’ll respond to your note as soon as I can. In the meantime, here’s a list of five questions that I get asked often. I’ve included brief answers to each one below. Take a peek. You might find the answer that you’re looking for—right away! [Include brief FAQs here] I hope those FAQs were helpful. Don’t worry, though—even if your question was one of the questions listed above, I will still send a personal response to your note as quickly as I can, just to make sure that your question or problem has been completely resolved. Talk to you soon!
However, I will be taking periodic breaks from binge-watching everything I’ve missed to check my email [once per day/every evening/occasionally] while I’m away.

I know a lot of people who never vacation for more than a few days because the email backlog becomes incredibly stressful upon their return; this is one way to meaningfully combat that which is somewhat in the employee’s control.
Also, you need to know your audience if you are going to go eccentric. Alison mentions that this message is fine in their culture, but it wouldn’t npbe appropriate for my somewhat formal field. And even if your workplace in general is casual, you might be contacted by someone outside. (In a tiny provincial courthouse I served in the past, there is a story going around that in the 80s a junior but elderly clerk used to address phone callers as hun and sweetheart and generally speak very informally. Most people thought it was funny, and then the President of Supreme Court called and… he didn’t).
