I had never seen one of these before up until a few weeks ago.
Think about if you received an auto-reply from a colleague that read somewhat like this…
“I can’t respond to your email right now, I’m working on this great project right now and will try to get back to you later.”
What’s the project?
How great is it?
What do I need to do, to be a part of it?
How can I help by keeping emails like mine out of your way?
Very simply this conveys interest, excitement, passion and of course, curiosity.
I haven’t used it yet, but hope to in 2017.
