A 15-minute morning inbox routine

This is a practical daily morning inbox routine. In the first 15 minutes after starting work, you sort what came in—so you protect focus and wellness for the rest of the day.

If you've ever spent a day opening and closing your mailbox in the morning, your inbox has become the master of your day. If you try to answer them one by one, 15 minutes turns into two hours, and important tasks get pushed to the afternoon.

Organizing your inbox for 15 minutes in the morning is not about ‘reading everything,’ but ‘sorting.’ Answer now, deal with it today, put it off for this week, delete it—if you divide it into four sections, you'll be done in 15 minutes.

Pick a fixed time, right after going to work, the first 15 minutes at home, or right before lunch, and repeat the same sequence every day. When you start in the same place with a cup of coffee, you create the connection that '15 minutes in the morning = clean up.' If you have already checked your emails on the subway on your way to work, use the 15 minutes after sitting in your office/desk as ‘just sorting’ time.

Close your mailbox when the timer rings.

Set a timer for 15 minutes and only open your inbox during that time. When the timer goes off, close your mailbox. ‘Just a little more’ puts the day in reactive mode. I spend 15 minutes just reading and sorting. Turn on smartphone notifications only for this time, and turn them off again after sorting is complete.

'Reply now', 'Place today at 2', 'This week', 'Delete'—you can label them with four different labels, or just add a star or flag. Gmail labels, Outlook folders, Slack Save for Later—the tools may be different, but the principles are the same. Long emails are classified by only looking at the first paragraph and signature.

Just read and reply later

Among those categorized as 'Reply Now', only those that are completed within 30 seconds will be processed immediately. Once 3 messages are received, the rest will be sent to ‘today’s 2 o’clock batch’. The goal for your 15 minutes in the morning is not to have zero inboxes, but to make a ‘what to get done today’ list. Even if you have 50 messages piled up in your ‘Later’ folder, you only need to pick out the 5 that you want to deal with today.

After sorting, move the ‘Today’s 2 o’clock batch’ list as a single line into the To-Do app or Notebook. Just write down a number, such as ‘5 emails, 3 Slack threads’. Close your inbox and move on to the next block of the morning—either focused work or preparing for a meeting. When the 15 minutes are up, you can turn notifications back on. If Slack's 'unread' badge bothers you, it helps to get into the habit of not looking at the numbers until deployment time.

Inbox is not a warehouse to be left open all day. With just two fixed sessions—15 minutes in the morning and 5 minutes in the evening—it becomes easier to stick to your daytime focus blocks. Coupled with batching replies twice a day, 'reading' and 'reply' are completely separated, increasing morning focus time. The first week may feel like 15 minutes is not enough, but it will save you time as you get used to sorting.
