Sick leave auto reply: 8 templates without over-sharing.

A sick leave automatic reply should say you are out, when you expect to be back and who to contact, without medical details. Pick a sample below.

Quick answer

Sick-day auto-replies should: (1) confirm you're out, (2) give an expected return time, (3) name a backup, (4) skip details. The 8 templates below cover one-day, multi-day, contagious illness, mental health, recovery from procedure, and 'I really shouldn't be working' scenarios.

→ The mechanical fix

Don't add 'urgent' clients calling you on top of being sick.

Routing handles the urgent stuff. You handle the rest later.

One-day sick

'Hi - I'm out sick today, back tomorrow. For urgent matters: [backup] at [email]. Otherwise I'll respond tomorrow.'

Multi-day sick (uncertain return)

'Hi - I'm out sick this week and will return when I'm feeling better, likely [estimated date]. For urgent matters: [backup] at [email]. I'll respond to non-urgent emails when I'm back.'

Contagious - extra cautious

'Hi - I'm out with a contagious illness through approximately [date]. To protect those I'd be meeting in person, I'm fully off until I'm cleared. For urgent matters: [backup]. I'll respond to non-urgent emails when I return.'

Mental health day

'Hi - I'm taking a mental health day today and will be back tomorrow. [Backup] is handling urgent matters: [email]. Thanks for understanding.'

(Or, if you prefer privacy: 'I'm taking a personal day' - equally valid.)

Recovery from procedure

'Hi - I'm recovering from a planned medical procedure and will return [date]. [Backup] has full authority on my matters during this window: [email] / [phone]. Thanks.'

'I shouldn't be working' (severe)

'Hi - I'm out for medical reasons and have very limited email access. [Backup name] is handling all urgent matters with full authority: [email] / [phone]. I'll respond to non-urgent emails when I'm able to return.'

Migraine / chronic condition flare

'Hi - I'm offline today managing a flare-up and will be back online when I'm feeling better, likely tomorrow. For urgent matters: [backup]. Otherwise I'll respond when I return.'

Family member illness (caregiver)

'Hi - I'm out caring for a family member through [date]. [Backup] is handling urgent matters: [email]. I'll respond to non-urgent emails when I'm back.'

Out for part of the day? Use a half day out of office message. Just one day off: one-day out of office messages. Out for longer: medical leave out of office templates that keep your health private.

Frequently asked questions

How do I write an automatic reply for sick leave?

Say you are out, give an expected return date, name a backup for urgent matters, and leave out medical details.

Do I have to say I am sick in my out of office?

No. "Out of office" or "taking a personal day" is enough. Your employer may have its own sick leave policy to follow.

How long should a sick leave auto reply be?

Two or three sentences. It only needs to confirm you are out, when you will be back and who to contact.
