Education Details: Here's an example (and here are 7 more out-of-office templates, too!) Hi there, I am OOO on PTO from Friday, December 1 - Tuesday, December 10 without access to email or voicemail. If this is urgent, please contact [NAME], otherwise I will respond to messages when I return.
Or, worse, when someone has left the organization and the organization hasn’t bothered to put up an OOO, so I’m just emailing a blackhole until I call or someone finally checks that inbox. I never fail to set up my OoO reply, and yet most of my external contacts don’t get them. Let’s say I work for LlamaCombs, with an name(@)llamacombs.com address, and this is a company who has two clients AlpacaBrush and VicunaShampoo. I work primarily with the second, and their internal directory lists my contact info as name(@)vicunashampoo.com. It works because any e-mail sent to the second address is auto-forwarded to the first. Except it messes up OoO replies big time. Because the auto-reply is sent to my own alternate address, not to the original sender, and I have no way to change that.

We’ve certainly come a long way since the honeymoon days of You’ve Got Mail, the 1998 Meg Ryan romcom in which each new electronic missive set Tom Hanks’ heart fluttering (and vice versa). These days, in tech circles, you’ll hear tales of folk who’ve set their email servers up to automatically delete unread emails after a week – before going on holiday for a full fortnight. Others have reduced the OOO to a single word in the subject line: “Nope.”
If one were concerned about the message rubbing people the wrong way, it’s certainly something that can work with a bit of rephrasing: “I’m out on leave from X to Y. All messages received during that time will be deleted. Please resend your request after Y, or else contact Z for urgent assistance.”
