A poorly worded out-of-office reply can lose clients or sour relationships. Experts share the rules for crafting an effective OOO message that protects your break and your reputation.
A bad out-of-office reply can cost you a client, sour a relationship, or even breach employment rights. The warning comes from etiquette experts, career coaches, and legal professionals who say many people get the automatic message wrong.
Debretts, the etiquette consultancy, says a good OOO should be polite and concise. Give a specific return date. Provide a backup contact. Avoid oversharing – holiday plans, second homes, expensive hobbies. Director Rupert Wesson said such messages can seem “smug” or like the sender is “trying too hard”.
“Some people will be delighted you are spending ‘quality time with your family’,” Wesson said. “Given that they are the ones emailing you and are hard at work, you could risk rubbing their noses in it.”
Charlotte Davies, a career expert at LinkedIn, said a good OOO does two things: shares your dates and points people to a backup contact. She recommends briefing the person covering you before you leave. “It helps whoever’s emailing you, and it protects your break too,” she said.
Humour carries real risk. Paul Fitzsimmons, head of sales and marketing at law firm Wilford Smith, gave examples that could land a professional in trouble. “I’m currently out of the office pretending this company doesn’t exist.” “If it’s urgent, call someone who cares.” “Emails received while I’m away will be deleted unread.”
Adam Murfet, a senior sales executive, said a former colleague lost a deal after a joke in an OOO angered a client. He thinks humour can help a person stand out when communication is increasingly AI-driven. His rule of thumb: “Always ask, would you put the same thing in an email?”
Vague availability language is another trap. Wesson said if you need to check email, say “I will be periodically checking emails” instead of “limited access”. Davies said UK workers have a legal right to uninterrupted annual leave unless their contract states otherwise.
A bare message that simply states “I’m out of office” with no return date or alternative contact creates uncertainty. That uncertainty leads to “just-in-case” follow-ups, Davies said, eroding the break and the relationship.
Commentators often complain about senders saying they will have “limited access to email” while away. The risk is it invites people to keep contacting you. Wesson said the phrase “limited access” is often ambiguous and can be worse than saying nothing.
For companies where client communication is critical, a stale or poorly worded OOO can look disorganised. The experts’ checklist includes: lead with a greeting, specify a return date, give a backup contact, be clear about availability, promise a reply within a few days after return, and switch off the OOO when back. A stale OOO, they said, can look disorganised.
