You are heading out for a week. Before you close the laptop, you set the auto-reply: “I am out of the office through the 24th with limited access to email. For anything urgent, please contact Dana in accounting at [email protected] or 940-555-0142.” Done. Reasonable. Helpful, even.
Here is the part almost nobody thinks about. That message does not only go to customers. It goes to every address that emails you while you are gone, including addresses you have never done business with and never will. One message to your inbox returns your travel window, your return date, the name of the person covering for you, a direct line to reach them, and your place in the org chart. We are not telling you to stop using out-of-office replies. They do a real job. We are telling you that most of them give away more than the job requires.
What a Standard Auto-Reply Hands Over
Pull up the last out-of-office message you used and read it as if you knew nothing about your company. Here is what a typical one confirms to a complete stranger.
- That you are gone, and for exactly how long. A specific return date tells anyone reading it how many business days they have before you are back at your desk asking questions.
- Who is covering, by name. Now a stranger has a real employee name, correctly spelled, in the correct department. That name can be used in a message to somebody else at your company.
- A direct route to that person. Publishing a colleague’s individual address and phone number saves customers a step. It saves everyone else a step too.
- Your title and reporting line. Auto-replies often inherit a signature block spelling out who reports to whom, which is the map somebody needs to make a fake request look plausible.
- Sometimes a personal cell number. People add these with good intentions, then forget the number is going out automatically to every sender for two straight weeks.
Why the Timing Is the Real Problem
No single detail there is a catastrophe. The issue is what they add up to for someone already working on a payment-request scam. Business email compromise, the general name for a scam where someone impersonates a person you trust and asks for money or a change to payment details, works best when the person who would normally catch it is unavailable. Your auto-reply announces exactly when that window opens and closes.
The scale is not hypothetical. The FBI’s Internet Crime Complaint Center reported 24,768 business email compromise complaints and $3,046,598,558 in reported losses in its 2025 Internet Crime Report. The mechanics are usually mundane: a believable request, a plausible sender, and a moment when verifying feels inconvenient. The National Institute of Standards and Technology, in its small business guidance on phishing, sums up the defense in one line: “Stop and take a moment to think about the request.” Harder to do when the person who would do the thinking is on a plane.
This is a process gap, not a horror story. Tightening the auto-reply is one small piece of not making your company easy to read from the outside, which we covered in our post on why phishing attempts keep getting through.
The Minimal Version That Still Serves Customers
A good external auto-reply answers one question: what should I do now? It does not need to cover where you are, when you left, or who is standing in. Something like this works: “Thank you for your message. I am away from email and will respond when I return. If you need help right away, please call our main line at 940-555-0100 or email [email protected].”
Shorter, friendlier, and it gives away nothing. The principles apply to whatever wording fits your business.
- Point to a role or a shared inbox, not a person. “Our support team” routes the customer just as well without publishing a colleague’s name.
- Use your published main number. If a number already appears on your website, using it costs nothing. A direct extension or a cell number is different.
- Drop the dates. “I am away from email” works as well as “out through the 24th” without handing over a calendar.
- Leave out the why. Nobody outside your company needs to know it is a wedding, a surgery, or a cruise with no cell service. That last one in particular is an invitation.
- Check what the signature appends. Many replies quietly attach a title, department, and mobile number below the message you wrote.
Set Internal and External Replies Differently
Here is the feature most people never turn on. The major business email platforms let you write two different auto-replies: one for people inside your organization and a separate one for everyone else. Your coworkers get the detailed version with dates, coverage, and a cell number. The outside world gets the short version.
In Microsoft 365, look in your mail settings for the automatic replies option, which includes a separate message box for senders outside your organization. In Google Workspace, the equivalent is the vacation responder in your general mail settings, with an option to send only to your contacts or only to people inside your organization. Menu layouts change, so find the setting by name rather than by a memorized click path.
One honest caveat. If you shut off external replies entirely, a customer who emails you gets silence, and for most owners that trade is not worth it. Write the short version instead of turning it off.
Coordinate Coverage So Urgent Requests Still Get Verified
A tight auto-reply does not help if the coverage behind it is vague. The risk is that your backup, wanting to be helpful and not wanting to bother you, approves something they would normally route to you.
- Hand off in a conversation, not in a footer. Tell your backup what you expect before you leave, so they are not learning their role from your auto-reply.
- Write down what they can approve alone. A dollar threshold and a short list of routine decisions removes most of the guesswork.
- Keep the callback rule in force. Any request to change bank details, send a wire, or pay a new invoice gets confirmed by voice, using a number you already had on file, never one supplied in the message.
- Make an unreachable approver a reason to wait, not a reason to skip a step. Say that out loud to your team.
- Give the backup explicit permission to say no. People approve things they should not because they are afraid of looking obstructive. Remove that fear in advance.
The Federal Trade Commission’s small business guidance on business email imposters also points owners at the technical side: when you set up business email, “make sure the email provider offers email authentication technology,” and teach staff “how to avoid phishing scams.” Authentication makes it harder for anyone to send mail that looks like it came from your company. It is a one-time setup, and it belongs in the same conversation as the broader case we made for treating security as ordinary operations.
The Bottom Line
Out-of-office replies are a courtesy worth keeping. What should go is the habit of writing them as though only customers will read them. Give outside senders a way to get help and nothing more. Give your own team the detailed version through the internal reply setting. Then make sure your backup knows what they can decide and which requests always get a phone call.
