The only thing I add to that boilerplate is if I’m working but mostly unavailable.
I do typically come back to hundreds of emails, and I prioritize what to read – things from my boss/leadership are first, followed by communication from my direct reports. I also sort them by conversation thread and read the end of them first, which reduces the burden.

My coworker tends to set his OOO for people to contact me, but he never bothers to tell me he’s going to be out of town and people may be contacting me. I’ll find out when I happen to email him and get the response. Not a huge deal, but the heads up would be nice! What if I was also on vacation?
In the Message and Language section, select the language and enter text, images, and hyperlinks into the Message field. For instructions on language and the use of snippets, click here. Pro Tip: Within the message body, we recommend that you don't use phrases such as: "We are currently out of the office" or "Our office hours are....." Instead, use generic phrases such as "We have received your message and will be in touch." This approach protects your SLA in marketplaces that use detectors to discourage automated responses, which look for these key phrases and may not approve the message as a valid response to reset the SLA.
