Rather than a number of days or vague phrasing like “this week,” giving exact dates helps prevent confusion and lets senders know when they can expect a response from you.
That’s right. An out-of-office response is an automated email message that will be sent back to anyone who shoots you an email while you’re on leave. They are important. For starters, you don’t want to appear snobbish, and… you might even get some new leads just by leaving a well-thought-of out-of-office email message.

The holiday out of office best wishes are sent to the offices when the staff of the office remains out of office for the holidays. The wishes are sent to the office marked to the staff to make them feel good. The wishes can be sent through mails and text messages to the office mails and numbers.
“For example, if a hacker knows that the chief financial officer of a company is OOO, thanks to the information in the auto-reply message, an attacker could impersonate the CFO on email and target another individual in the company’s finance team asking them to make a payment or update bank details for them while they are offline,” says Sadler.
