How to Write a 'Back Soon' Message for Extended Leave (Parental, Medical or Sabbatical)

A quick out-of-office for a two-week holiday is easy — everyone's done one. Extended leave is a different problem entirely: months, not days, and customers who might genuinely need someone else to help them while you're away. 💖 Get the message wrong and you either leave people hanging with no real answer, or overshare details about your personal life that customers never needed and you'll wish you hadn't put in writing.

What most businesses get wrong

The most common mistake is copying the tone of a one-week holiday auto-reply onto a much longer absence — "back soon!" means something different when it's six weeks versus six months, and vague timing frustrates people who need to plan around you. The second mistake is the opposite: oversharing the reason for leave in detail when a simple, dignified "I'm taking some extended leave" covers it completely — customers don't need or want a health update, they need to know what happens to their enquiry.

How to set it up properly

Update every channel at once — email auto-reply, voicemail, website contact page, Google Business Profile and social bios — rather than just the one you remember first. If you have a backup person or team, brief them before you go so they're not caught off guard by an enquiry referencing you. Set a calendar reminder to update everything back to normal the week before you return, so you're not still auto-replying "on leave" a fortnight after you're back at your desk.

Mistakes to avoid

• Leaving the return date so vague ("back soon") that regular clients don't know whether to wait or go elsewhere.
• Oversharing personal or medical details that weren't necessary and can't be un-shared later.
• Forgetting to update every channel, so customers get mixed messages depending on where they find you.
• Not briefing your backup contact properly, so they're blindsided by enquiries referencing your absence.
• Going quiet on social media entirely instead of posting the update once, clearly, and then stepping back.

Frequently asked questions

Do I need to explain why I'm taking leave?

No — a simple "extended leave" or "personal leave" is enough for almost any audience. The exception is if being specific (like parental leave) actually helps customers understand the timeline better, in which case it's your call to share only as much as feels right.

What if I genuinely don't know when I'll be back?

Give the best approximate window you can ("later this year," "from Q3") rather than nothing at all — an approximate answer is far more useful to a planning customer than no answer, and you can always update it if the timeline shifts.

Should I keep posting on social media while I'm away?

That's entirely a personal choice, and there's no rule either way. Some business owners like to stay lightly visible; others prefer a clean break. What matters more than the choice itself is being consistent with what you said you'd do, so customers aren't confused by mixed signals.

What if a client is upset that I'm not personally available?

That's a reasonable feeling on their part, and it's worth acknowledging rather than dismissing — "I understand that's frustrating, and [colleague] is genuinely well placed to help in the meantime" respects the relationship without you having to cut your leave short.
