Gmail has 3 billion users, a figure Google published in January 2026. Google Workspace reports 3 billion users and 13 million paying customers. Gmail blocks more than 99.9% of spam, phishing and malware, which Google puts at nearly 15 billion unwanted messages a day.

Every number on this page links to whoever measured it.

Most Gmail Statistics Are a Game of Telephone

Here’s how a Gmail statistic gets made. Somebody reads a real number, rounds it, and writes it into a listicle. Then they cite the listicle they read it in rather than the source.

Ten posts later the number has drifted, the date is gone, and nobody in the chain has read the original. That’s the game of telephone, and this topic is riddled with it.

We rebuilt this page in August 2026 by chasing every figure back to whoever measured it. Fourteen statistics and thirteen source links didn’t survive. We say which ones below, and why, because a deletion is more useful to you than a number nobody can check.

What Changed in This Update

Old claim on this page	What we found	Now
“More than 1.5 billion Gmail users, Google confirmed in 2018”	The 1.5 billion figure is real, but Google published it on 1 April 2019, not in 2018. It’s also six years stale.	Replaced with 3 billion, January 2026
Gmail is 27% of email opens, Apple iPhone 29%	That was Litmus data from the first half of 2018	Replaced with Litmus May 2026 data
“281 billion emails sent daily”	Traces to Radicati, whose report is paywalled. No free page carries the figure.	Deleted
“92% of startups choose Gmail”	Sourced to a vendor customer-stories page, no methodology published	Deleted
“The average worker receives at least 121 emails per day”	Traces to an aggregator with no underlying study	Replaced with Microsoft’s own 117, measured from telemetry

How Many People Use Gmail?

Gmail has 3 billion users. Google’s VP of Product for Gmail, Blake Barnes, wrote it on the company blog on 8 January 2026.

Today, 3 billion users rely on Gmail to connect and get things done.

That’s a first-party number from the company that operates the service, which makes it the strongest figure available on this topic. Google publishes no methodology alongside it, so treat “users” as Google’s own definition rather than a comparable industry metric.

Gmail’s User Count Over Time, From Google’s Own Posts

Figure	Date Google published it	Where
1 billion monthly active users	February 2016	Announced at an Alphabet earnings call
1.5 billion users	1 April 2019	Gmail’s 15th birthday post on blog.google
More than 2.5 billion users	18 December 2024	A Gmail security post on blog.google
3 billion users	8 January 2026	A Gmail product post on blog.google

Notice the gap between 2019 and 2024. For five years the only Gmail number in circulation was 1.5 billion, and that vacuum is where the invented figures grew.

The most common of them is “1.8 billion Gmail users.” Google has never published it. It sits neatly between two real Google figures, which is exactly what a rounded-then-repeated number looks like.

Some of that 1.5 billion coverage was itself misdated. Plenty of pages, including an earlier version of this one, credited it to 2018. Google’s own post is dated 1 April 2019.

Alphabet Doesn’t Disclose Gmail User Numbers in Its Filings

We read Alphabet’s FY2024 Form 10-K in full and searched it. It contains no Gmail user count, no Workspace user count, and no “monthly active” figure of any kind.

Gmail appears once, in a product list describing Google Services. So every Gmail user number in circulation comes from a blog post or a keynote, never from an audited filing. That’s worth knowing before you put one in a board deck.

Google Workspace: 3 Billion Users, 13 Million Customers

Google published both figures on 22 April 2026. Workspace “is where work happens for over 3 billion users and more than 13 million customers.” The customer number is the more useful of the two.

Google has used “3 billion” for Workspace since at least October 2022, unchanged. Treat it as a rounded marketing constant rather than a tracked metric. A figure that holds steady for four years is measuring little.

Roughly three-quarters of all Gmail users reach it on mobile, per reporting around Gmail’s 2016 billion-user milestone. Google hasn’t updated that split since.

Gmail’s Email Client Market Share

Gmail accounts for 24.11% of tracked email opens, second to Apple at 64.66%. Litmus publishes this monthly, and the figures below are its May 2026 data.

Email client	Share of opens, May 2026
Apple (Mail, iPhone, iPad)	64.66%
Gmail	24.11%
Outlook, desktop	6.49%
Yahoo Mail	2.57%
Google Android	1.38%
Outlook.com	0.38%
Thunderbird	0.21%

Read those numbers with the method in mind, because Litmus states it openly. The data comes from “real-life Litmus customers who are using Litmus Email Analytics in their own emails.” That means marketing email rather than all mail.

Apple’s 64.66% is inflated by Mail Privacy Protection, which auto-opens messages whether a human read them or not. Litmus flags those as not reliable opens. Litmus also notes that image blocking can skew any client’s number in either direction.

So this measures where marketing email gets opened rather than how many mailboxes exist. According to a Litmus study from the first half of 2018, Gmail was at about 27% and Apple’s iPhone at 29%. The Apple share has moved a long way since MPP shipped.

For a feature-level comparison rather than a share-of-opens one, see Outlook vs. Gmail.

Gmail Spam and Security Statistics

Gmail blocks more than 99.9% of spam, phishing and malware. Google’s phrasing, from an October 2023 post, is the most quotable version of the claim.

Gmail’s AI-powered defenses stop more than 99.9% of spam, phishing and malware from reaching inboxes and block nearly 15 billion unwanted emails every day.

Google restated the 99.9% figure in December 2024. Both are first-party claims with no published methodology, which is normal for security vendors and still worth stating.

Older reporting put the phishing share of that at more than 10 million phishing emails blocked every minute. According to Gmail, its filter’s false-positive rate has been measured in fractions of a percent since 2015.

If your own messages keep landing in the wrong folder, the mechanics matter more than the aggregate rate. Our guide to why emails go to spam covers the authentication side.

There Is No Reliable “Percentage of Email That Is Spam”

We went looking for one and came back empty. Cisco Talos publishes live email reputation data. Its tables render only in a browser, and they report per-sender volume rather than a global spam share.

Statista and similar aggregators do publish a percentage, and they’re reselling someone else’s paywalled research. So the honest position is that no free primary source states what share of world email is spam. Google’s “nearly 15 billion unwanted emails every day” is a real number about one provider, and it’s the closest thing available.

Global Email Volume: The Number We Deleted

Almost every email statistics page you’ll read cites a daily send volume. The figure traces to The Radicati Group, whose Email Statistics Report is a paid product.

We checked radicati.com directly. What’s publicly readable is a table of contents and a Purchase button, and the free executive-summary PDFs for older editions returned nothing. Daily traffic and spam volumes are listed as contents of the paid report.

Wtf, so everyone quoting it bought the report? Almost certainly not. They quoted somebody who quoted somebody, and the chain ends at a paywall nobody walked through.

That’s why the “281 billion emails per day” line that used to sit on this page is gone. If you need a defensible volume figure, use one a company published about its own service, like Google’s 15 billion blocked messages.

How Much Email Does a Worker Get Each Day?

The average worker receives 117 emails a day. Microsoft published that in its Work Trend Index special report “Breaking down the infinite workday” on 17 June 2025. The methodology is stated on the page.

The average worker receives 117 emails daily, most of them skimmed in under 60 seconds.

Microsoft measured this from “aggregated and anonymized Microsoft 365 productivity signals, ending February 15, 2025,” excluding education and European Union tenants. That’s telemetry rather than a survey, which makes it unusually strong for this kind of claim.

Two more from the same report. Workers handle 153 Teams messages on a typical weekday, and 40% of people online at 6 a.m. are already reviewing email.

The older “121 emails per day” figure that sat on this page came from an aggregator with no underlying study attached. Microsoft’s number is close, and it’s measured.

Our Own Numbers: Response Time Across 25 Million Emails

EmailAnalytics is a Gmail and Outlook add-on that visualizes team email activity. It reports average response time per person, busiest hours, and volume by sender.

We publish a quarterly benchmark study from that data. It’s the one dataset on this page we can describe end to end.

The Q2 2026 edition covers 1 April to 30 June 2026 and draws on 25,384,649 emails across 22 sectors. Here are the headline figures.

Metric	Q2 2026	Change vs Q1
Average response time, work hours	4h 10m	Down 1h 7m
Average response time, elapsed	12h 55m	Down 3h 27m
Emails received	21.9 million	Up 14.3%
Emails sent	3.5 million	Up 3.4%
Fastest sector	3h 14m, Association and Property Management	42m faster
Slowest sector	6h 5m, Wholesale Construction Products	Not stated

Work-hours response time fell 21% quarter over quarter while inbound volume rose 14.3%. Teams handled more email and replied faster, which isn’t the trade-off most people expect.

The industry spread is 2.8 hours between the fastest and slowest sector. That gap is the argument for benchmarking against your own industry rather than a global average.

Thursday is the heaviest inbound day at 20.1% of weekly volume, and weekends carry 9.7%, down from 10.4% in Q1.

How We Collect It

The study uses aggregated, anonymized metadata from EmailAnalytics customers on Gmail and Outlook, both paying and trial. Only metadata is collected, and message bodies are never read or stored.

Personal addresses are excluded so the sample reflects professional use. Zero-activity users are removed, and the top and bottom 5% by volume are trimmed to limit outliers.

Timestamps are localized to each user’s own configured time zone, so the day-of-week and hour-of-day patterns reflect real working schedules. Industries are self-reported at onboarding.

Gmail History and Storage, in Dates

Google went live with its email platform on 1 April 2004, which many people took for an April Fools’ joke. It gave users 2 GB of free storage at a time when rivals offered a few megabytes.

Google later consolidated to 15 GB of free storage shared across Gmail, Drive and Photos in May 2013. That 15 GB is still the free allowance today, thirteen years later. Google now counts WhatsApp backups on Android against it too.

The February 2009 outage remains the most-cited failure, affecting more than 100 million accounts for roughly two and a half hours.

Gmail currently supports 105 languages, per its Wikipedia entry. Google publishes the list in-product rather than in a countable help page. This one is a secondary source and we’re saying so.

For what shipped recently rather than in 2013, see our roundup of new Gmail features.

Email Behavior Statistics Worth Keeping

A few numbers on the old version of this page survived the audit, because their publishers measured something and said how.

• Knowledge workers spend 13 hours every week on email, per McKinsey Global Institute’s Social Economy report.
• Emails containing between 1 and 3 questions draw more replies than emails with none, from Boomerang’s study of 40 million-plus messages.
• According to ZDNet, the replacement cost of a lost business mailbox runs into thousands of dollars.

Faster replies are a gateway to higher productivity, and the same logic drives our own benchmark work. For the outbound side, see our sales email subject lines and our email statistics for sales professionals.

What We Deleted and Why

Thirteen source links came off this page in the August 2026 update. Naming them is the point, because you’ll see the same figures on other pages tomorrow.

• A blog citing Gmail’s user count as its own authority, when Google publishes the number directly.
• A Radicati executive summary PDF for daily email volume. The PDF returns nothing and the figures live in the paid report.
• Two Statista charts. Statista is an aggregator, so a Statista citation is a pointer to a source we couldn’t reach.
• A vendor customer-stories page behind the “92% of startups” and “20 billion emails” claims, with no methodology attached.
• An aggregator’s email statistics index behind the 121-emails-per-day figure.
• Several marketing-blog roundups carrying open rates, click rates and spam-flag percentages with no underlying study reachable from any of them.

None of those numbers is necessarily wrong. They’re just unverifiable, and an unverifiable statistic in a statistics article is worse than a gap.

Frequently Asked Questions

How many people use Gmail?

Gmail has 3 billion users, a figure Google published on 8 January 2026 on its own blog. That replaced the 2.5 billion figure Google gave in December 2024. Google publishes no methodology alongside it, so “users” means whatever Google counts internally.

Is Gmail’s 1.8 billion user figure real?

No. Google has never published 1.8 billion, and the number appears only in statistics roundups citing other roundups. It falls between Google’s real 1.5 billion figure from 2019 and its 2.5 billion figure from 2024.

What is Gmail’s market share?

Gmail accounts for 24.11% of tracked email opens, per Litmus data from May 2026, behind Apple at 64.66%. That measures marketing email opened by Litmus customers’ recipients rather than mailboxes in existence. Apple’s share is inflated by Mail Privacy Protection auto-opens.

How much spam does Gmail block?

Google states that Gmail stops more than 99.9% of spam, phishing and malware, which it puts at nearly 15 billion unwanted emails a day. Google published that phrasing in October 2023 and restated the figure in December 2024. No methodology accompanies either statement.

How many emails are sent per day worldwide?

No free primary source publishes this. Every widely quoted figure traces to The Radicati Group, whose Email Statistics Report is a paid product with no free summary carrying the number. We deleted the figure from this page rather than repeat an unverifiable one.

How many emails does the average person get per day?

Microsoft measured 117 emails a day for the average worker. It published the figure on 17 June 2025 in its Work Trend Index report on the infinite workday. It came from aggregated Microsoft 365 telemetry ending 15 February 2025, excluding education and European Union tenants.

What is a normal email response time?

Our Q2 2026 benchmark of 25,384,649 emails found an average of 4 hours 10 minutes in work hours, and 12 hours 55 minutes elapsed. The fastest sector averaged 3 hours 14 minutes and the slowest 6 hours 5 minutes. Compare against your own industry rather than the global average.
