The short answer
- An out-of-office reply is an automatic message, not a decision. The prospect has not said yes or no, so do not answer it and do not count it as engagement.
- Read it for three things: a return date, a named backup contact and any sign that the person has left the company. Each one has its own next step.
- Pause the sequence for that prospect, then re-send one touch a few working days after the return date. Do not send the next scheduled step into the auto-reply.
- Label these replies as out of office so they stay out of your positive reply numbers and your Needs Reply queue. See out-of-office handling and reply labeling.
- Master Inbox labels out-of-office replies as they land and runs the pause and resume as a workflow, with a free 7-day POC to try it on your own replies.
Why trust this guide?
This guide is written by the Master Inbox team and reviewed by our founder, Abdul Mukati. We build a reply inbox for outbound teams and agencies, so we see every kind of auto-reply that lands next to real answers. Master Inbox is one of the tools mentioned, and we say where it fits. The example replies are illustrative and the timing advice is a recommendation to adapt, not a statistic. The facts about auto-responders come from the pages in the Sources section, which we fetched and checked.
This post is part of a series on handling each type of reply. The overall method is in the cold email reply management guide. Two close companions are how to handle not now replies, which covers real timing requests, and how to handle wrong person replies, which covers people who have left or changed roles.
What an out-of-office reply is, and what it is not
An out-of-office reply is sent by the prospect's mail system, not by the prospect. It usually says the person is away until a date and may name someone to contact instead. Because a machine wrote it, it tells you nothing about interest in your offer.
That is why it deserves its own label. If it sits in the same pile as real answers, two things go wrong. Reps waste time opening it, and your reply counts look better than they are. The glossary entry on out-of-office handling describes the goal: detect these messages, filter them from the queue and capture the return date.
Not every auto-reply is the same. Sort them into four kinds:
- Away with a return date. The most common kind. The person is back on a known day.
- Away with a backup contact. The message names a colleague for urgent matters.
- Away with no date. "Limited access to email" or "on leave" with no end. Treat it as a soft not now.
- Left the company. The mailbox owner no longer works there. This is closer to a wrong person reply than to an out-of-office one.
How out-of-office replies behave
Knowing how auto-responders work saves you from two mistakes: expecting a second message and replying to the machine.
- Most send once per sender. Microsoft says its automatic replies are sent once to each person who emails you during your absence. Google says its vacation responder replies the first time someone messages, and may send another if they write again after four days. So a follow-up of yours inside that window will usually not produce a second auto-reply.
- They run between two dates. Google's reply starts at 12:00 AM on the start date and ends at 11:59 PM on the end date. Wording varies, so read whether the date is the last day away or the first day back.
- Some are limited to contacts. Both Google and Microsoft let people send the reply only to their contacts. A cold email may therefore get no auto-reply at all from someone who is away, which is why the absence of one proves nothing.
- The standard says machines should not answer machines. RFC 3834, the internet standard on automatic responses, says an automatic response should not be sent to a message that carries an Auto-Submitted header, and that automatic replies should carry that header themselves. This is why you should never configure a reply to an auto-reply.
How to handle out-of-office replies in 6 steps
- Detect and label the reply. Tag it as out of office the moment it lands, either by rule or with AI labeling. The label is what keeps the reply out of your hot queue and out of your positive reply count.
- Read it for the return date. Write the date on the prospect record. If the message gives a range ("back Monday 9 November"), use the first working day after it. If it gives only "next week", choose the following Monday.
- Pause the sequence for that prospect. A scheduled step should not land on top of an auto-reply, and a sequence that carries on sending to an absent person is wasted volume. Pause the contact, not the campaign. Learn how follow-up cadence spacing affects the restart.
- Check for a backup contact or a departure. If a colleague is named for urgent matters, do not email them yet unless your message is genuinely urgent. Add them to the account as a possible second contact. If the message says the person has left, move the lead to the wrong person process and look for the new owner.
- Resume a few working days after the return date. A person back from leave faces a full inbox. Wait two to three working days, then send one touch. Keep it short and let it stand alone.
- Close the loop. If the person replies for real, label it again by intent and route it. If there is no answer, return the contact to the normal cadence and note the pause in the record.
Teams often skip step 2. Without a return date on the record, the pause is open ended and the lead quietly disappears.
Three illustrative example replies
These show the shape of the messages and what to send next. Wording is yours to adapt.
Example 1: away with a return date
Illustrative example, not a real customer message.
Thanks for your email. I am out of the office until Monday 9 November with limited access to email. I will reply when I return.
Do not answer this. Pause the contact and set a restart for Wednesday 11 November. The message you send then can be short:
Subject: Re: your team's reply workflow
Hi Sam, I wrote a few days ago while you were away. In short: we help outbound teams keep every reply in one inbox so none go missing. If that is on your list this quarter, I can send a two line summary. If not, tell me and I will stop.
Example 2: away with a backup contact
Illustrative example, not a real customer message.
I am away until the 17th. For anything urgent, please contact Alex in operations.
Your note is not urgent, so do not contact the backup yet. Save the name as a possible second contact on the account, pause the original contact until the 17th and resume as in Example 1. If you have a real reason to reach the account sooner, a one line message to the backup is fine:
Hi Alex, I wrote to Sam about reply handling and saw they are away. Are you the right person to ask about it, or should I wait for Sam?
Example 3: left the company
Illustrative example, not a real customer message.
Please note I no longer work at this company. Messages to this address are not monitored. For help, contact the main office.
This is not an out-of-office reply. Relabel it, stop the sequence for the address and remove it from the list so it does not bounce later. Then look for the new owner of the role and start a fresh sequence for them. Our guide to wrong person replies covers that step.
Decision rules
Use this table to decide in a few seconds. The timings are recommendations, not benchmarks.
| What the message says | Label | Action | Restart |
|---|---|---|---|
| Away until a stated date | Out of office | Pause the contact, store the date | Two to three working days after the return date |
| Away, no end date | Out of office | Pause, add a review reminder | Check again in two to three weeks |
| Away, backup contact named | Out of office | Pause, save the backup as a second contact | After the return date, or contact the backup if urgent |
| No longer at the company | Wrong person | Stop and remove the address | New sequence to the new owner |
| Ticket or acknowledgement | Auto-reply | No action, keep out of reply counts | Continue the normal cadence |
| Away, but adds "reply with details" | Review | A human reads it | Treat as a real request when they return |
Common mistakes
- Replying to the auto-reply. Nobody reads it, and it clutters the thread.
- Counting it as a reply. It inflates reply rate and hides the real positive replies. Keep a separate label so reports stay honest.
- Letting the next step send. A follow-up that lands while the person is away is likely to be buried under everything else that arrived.
- Missing the departure notice. "No longer with the company" belongs with wrong person replies, and the account may still be worth pursuing through someone else.
How to do it in Master Inbox
Master Inbox is built for the reply side of outbound. It works alongside your sequencer, CRM and support desk, so you keep sending where you send today.
- Capture. The Unibox reads the mailboxes themselves, so auto-replies, forwards and CC replies from Smartlead, Instantly, EmailBison, Lemlist and others arrive in one threaded view.
- Label. AI labeling tags every reply by intent as it lands. Out of office is one of the labels, and you can adjust the taxonomy to add separate tags such as "away with backup contact" if your team wants them.
- Automate. Workflows are triggered by label. An out-of-office label can pause the contact in the connected sequencer and resume it later, using the pause and resume actions available for Smartlead, Instantly, EmailBison, PlusVibe and HeyReach.
- Keep the queue clean. The Needs Reply view shows replies waiting for a person. With auto-replies labeled separately, it holds the replies that matter, and reporting keeps them out of your response numbers.
- Sync to the CRM. Label and status changes can sync to HubSpot and other CRMs, so the return date and the pause are visible on the record. See CRM sync.
- Reply Agents. Reply Agents can handle follow-ups once a person is back, with a human approving drafts first.
Agencies can keep a separate label set per client in client workspaces. Plans are priced on mailboxes and client workspaces, with unlimited users on every plan, and the details are on the outbound teams page and in pricing.
Frequently asked questions
Should I reply to an out-of-office message?
No. It is an automatic message with no decision in it, so there is nothing to answer. Pause the sequence for that contact and send your next touch after the return date.
How long should I wait after the return date?
Two to three working days is a sensible starting point, because the first days back are spent clearing the inbox. This is a recommendation to adapt to your own results, not a benchmark.
Should I email the backup contact named in the message?
Only if your message is genuinely urgent. Otherwise save the name as a second contact on the account and wait for the original recipient to return.
Do out-of-office replies count as replies in my reports?
They should not. Give them their own label and exclude them from reply rate and positive reply rate, so those numbers reflect people who chose to respond.
What if the message says the person has left the company?
Treat it as a wrong person reply: stop the sequence, remove the address and look for the new owner of the role. Our guide to wrong person replies covers the steps.

Keep the pause, lose the noise
Label the reply, store the date, pause the contact and restart a few working days later. That small routine keeps auto-replies out of your numbers and keeps leads in play. If you want the label, the pause and the restart set up for you, Start your free 7-day POC.
