One thing that really bothers me in out of office messages is “contact my supervisor” without listing the supervisor’s name. I work in a company with 4 large service departments, and each department is broken into multiple smaller teams. I don’t have a great grasp on who is on or who leads which smaller team, and we don’t have an org chart with that much detail readily available. If you’re saying to contact someone, I think you should always include the person’s name and contact information, not just “my supervisor”, “one of my team members”, etc. !
Setting up an out of office message is quite simple. It can be set using the auto-reply function of your mail provider or program – just don’t forget to turn it off when you return!

Use your absence as an opportunity to show off to customers and peak their interest in your content. Sending an out-of-office email is a good way to provide clients with more details about your business. Offer a link to an interesting online resource that your company has developed, like a blog post. This way, recipients are made aware of which lines of business your company are actively engaged in.
