How many emails does the average person have?

Last reviewed: September 27, 2026 · Markdown version

Nobody publishes a current, representative count. The best figures you can actually open come from two small academic studies that counted real mailboxes, and both show the same thing: the "average" is dragged far above the typical mailbox by a few enormous ones. This page is about how many emails people keep. How many arrive each day is a separate question with its own page.

What Google publishes: one threshold, no average

Google gives no average mailbox size for Gmail users. The only count it documents in this area is a ceiling on one layout: "If you have more than 250,000 emails in your inbox, you can't use the 'Default' inbox type" (Organize your emails into categories, read 27 September 2026). That tells you such inboxes exist. It says nothing about how common they are.

2006: 600 work mailboxes, counted

Microsoft researchers analysed the mail of 600 people at "a high-tech company", all using Outlook. Their table gives averages with medians alongside (Revisiting Whittaker & Sidner's "Email Overload" Ten Years Later, Fisher and colleagues, CSCW 2006, read 27 September 2026):

Everything kept: a mean of 28,660 items, median 15,797.
Inbox only: mean 1,150, median 512 — "half of our participants kept under 512 messages".
Unread in the inbox: mean 153, median 7.

The authors describe the archive sizes as "distributed in a power-law curve". Read that as: a few people with vast archives pull the mean up, and the median is the better picture of an ordinary mailbox.

2012: 19 Gmail users, personal and work

A CHI 2014 paper repeated the count on Gmail, from screenshots of 19 US participants' accounts, recruited because they used Gmail's web version from a desktop several times a week (Overload is Overloaded: Email in the Age of Gmail, Grevet and colleagues, read 27 September 2026). Its table labels the data 2012. For personal Gmail:

Total messages: mean 18,421, median 7,035.
Inbox: mean 15,030, median 3,500.
Unread in the inbox: mean 4,846, median 421.

Their work Gmail inboxes were smaller: mean 3,003, median 1,483. The authors' own reading is that people keep far more in personal inboxes than in work ones and archive less than Outlook users did.

Why neither is "the average person"

Both samples are tiny next to the number of email users, neither was drawn at random from the public, and the newer data is well over a decade old. The researchers say as much: the 2006 paper notes that "past activity is invisible" to its method because everyone had already deleted some mail, and the 2014 paper says differences between the studies "could be a result of comparing email behavior across three different email clients". So take the direction, not the digits: medians sit far below means, and personal inboxes hold more than work ones.

You will see bigger, rounder numbers quoted elsewhere. We could not open a primary source for the ones we came across, so they are not repeated here.

Your own number is two clicks away

On a computer, Gmail prints a count above the message list; the steps, and the difference between messages and conversations, are on how many emails do I have. If the figure is large, the useful follow-up is not how you compare with anyone else but whether it causes a real problem. That test takes three questions.
