Should You Check Email Only Three Times a Day?

The useful starting point is your work. A designer reviewing feedback, someone managing a live support queue, and a person waiting for a school message have different reasons to keep an inbox nearby. Before choosing a checking frequency, ask how quickly the messages you receive actually need a response.

What the three-check experiment actually tested

In Kushlev and Dunn's 2015 experiment, 124 adults experienced two conditions in randomized order across two weeks. One week, they were asked to check email three times daily, close the inbox otherwise, and switch off alerts. The other week allowed unrestricted checking.

Reported daily stress was lower during the limited week. Average reported checking was 4.70 times daily, compared with 12.54 during unrestricted checking. Three was an instruction; the experiment did not establish an optimum.

The sample needed some flexibility in email use, measures were self-reported, and the trial was short. Because alerts and inbox availability changed together, their separate contributions remain unclear.

What happened when email was removed entirely

A 2012 workplace study by Gloria Mark, Stephen Voida, and Armand Cardello took a more drastic approach: 13 information workers went without email for five workdays. Researchers compared that period with normal email use using computer logs, interviews, and heart-rate monitors.

Without email, participants switched between computer windows less frequently and spent longer in each window. Heart-rate-variability measures also indicated lower stress. Those results are interesting, but the experiment was small, took place in one organization, and tested a complete cutoff rather than a three-check schedule. Time in one computer window is also a particular measure of focus, not a direct count of useful work completed.

For your own trial, it helps to define what matters: finishing a piece of writing, reviewing a document, or completing a task before the next inbox visit. A quiet screen by itself does not tell you whether the work went well.

Why the workplace matters

A 2022 quasi-experimental study by Indy Wijngaards, Florie Pronk, and Martijn Burger examined a company-led batching intervention at a Dutch financial-services organization. It found lower emotional exhaustion immediately afterward, particularly among workers handling high email volumes and those who believed instant replies were not expected.

The benefits were not sustained at the two-week follow-up, and work engagement did not significantly improve. There was substantial dropout, and the setting was a single organization. This is evidence that context and implementation deserve attention, rather than a reason to prescribe the same routine to every team.

Consider a practical conflict: your calendar says “focus time,” but a colleague believes an email is the fastest way to get your approval. You can close the inbox and still spend the next hour wondering whether you are delaying them. An explicit agreement gives both of you something clearer to work with.

A practical way to try fewer checks

This is a suggested personal experiment, not the protocol of any study above. Use it only within the response obligations of your role.

1. Separate a deadline from an expectation

Look at the messages you actually handle. Which ones need action in minutes? Which can wait until later today? Which could reasonably wait until tomorrow? Ask the people involved rather than guessing what silence means to them.

If your job requires continuous inbox coverage, discuss a handoff or a protected interval before changing it. A smaller period with reliable coverage may be more workable than a whole-day schedule you cannot maintain.

2. Name one task and its next email window

Choose an activity with a clear stopping point. For example: “I will finish reviewing this section, then check email at 11.” The time is an example, not a research-backed minimum. Put the next check where you can see it, so remembering the plan does not require reopening the inbox.

Decide what a check includes. Reading the inbox briefly to identify anything urgent is different from answering every message and reorganizing folders. Make the session's purpose explicit so a quick review does not quietly become the rest of the morning.

3. Agree on an urgent route

Tell the relevant people how to reach you sooner if something genuinely cannot wait. Depending on your work, that might be a call, a designated contact, or the channel your team already uses for urgent issues. Avoid creating another channel that everyone must watch continuously.

4. Match the settings to the agreement

On iPhone, Focus can allow chosen people and apps while silencing others. Configure it around the contact route you agreed on, then test that route before relying on it. Apple also lets you adjust notifications by app.

Consider where you also receive email. If the same message still appears on a computer or another device, changing only the phone's alert setting may leave that interruption in place. Treat each device as part of the setup you are testing.

Alerts and self-initiated checking are separate decisions. If you repeatedly open a silent inbox, note what prompted the visit: a specific question, a natural break, uncertainty, or simply reaching for something familiar. Our guide to the checking habit explores that broader pattern.

5. Review the work and the missed messages

After a few comparable workdays, ask whether you completed the task you meant to protect, whether anything important waited too long, and whether the checking plan itself felt manageable. Keep a simple note rather than relying on a particularly good or bad afternoon.

If fewer checks meant a large backlog at the end of the day, shorten the gaps or change what you handle in each window. If the urgent route was overused, revisit the agreement. The goal is a routine you and your colleagues can use, not perfect compliance with someone else's number.

Make responsiveness predictable

“I check email three times a day” is a schedule. “You can expect a reply by this time, and here is how to reach me sooner” is an agreement. Start with the second, then choose a checking routine that supports it.
