2024 Market Leaders in Business Productivity: Microsoft 365, Google Workspace & Gmail

In the relentless flux of the business and productivity software arena, certain brands consistently define how professionals organize, communicate, and create. By the second quarter of 2024, a trio—Microsoft 365, Google Workspace, and Gmail—remain entrenched as the dominant forces in the marketplace. Powered by an intricate ecosystem of web platforms, mobile applications, and evolving advertising strategies, these titans continue to both set the pace and shape user expectations. Drawing on in-depth insights from Sensor Tower, this analysis unpacks the state of these leading brands and places them in the broader context of enterprise productivity technology.

The Marketplace: Maturity and Momentum​

The business software sector is no longer the fragmented, experimental space it once was. Over the last decade, suite-based platforms that centralize essential productivity tools—email, document editing, collaboration, and storage—have proven their staying power. Today, switching costs remain high, and organizations tend to standardize around the most reliable and integrated solutions. Thus, it’s no surprise that in Q2 2024, market leadership remains with those offering seamless, cross-device environments.
Microsoft 365, Google Workspace, and Gmail represent not only state-of-the-art productivity technologies, but also some of the best examples of successful SaaS business models, leveraging both cloud and device-based user engagement. Assessing their comparative performance, user reach, and advertising tactics provides a window into both the current zeitgeist and the near-term future of enterprise software.

Microsoft 365: The Ubiquitous Behemoth​

Microsoft’s productivity offering, historically known as Office 365, has become a keystone of workplace software. Its digital footprint is vast—spanning well-known web domains like forms.office.com, microsoft365.com, and office.com, as well as ubiquitous mobile and desktop apps including Microsoft Word, PowerPoint, and OneDrive.

Audience Trends: Wide But Some Fraying at the Edges​

Microsoft 365 retained a robust monthly deduplicated audience in Q2 2024, with office.com routinely drawing over 2 million unique web visits every month. While this is a testament to the platform’s centrality in both enterprise and education, granular numbers show some volatility:

• Forms.office.com saw a drop in regular visits, decreasing from 14 million to around 12 million by June. The slowdown could signal market saturation, competition from specialized survey tools, or workflow changes post-pandemic, where real-time, collaborative data collection has diversified to include emerging platforms.
• The overall digital ecosystem continues to post formidable numbers, but the downward trend in some segments suggests a need for continued innovation and user engagement.

App Engagement: Outlook Soars, Word Stabilizes​

Microsoft apps run deep into user work habits. Microsoft Outlook stands out, clocking in over 5 million monthly active users. This reinforces Outlook’s position as the default communications and scheduling hub for millions. In contrast:

• Microsoft Word, still a mainstay for document creation, saw a gentle contraction, with monthly active users stabilizing at 295,000 by June. Such a plateau is unsurprising considering the rise of collaborative, cloud-first editors.
• Other apps like OneDrive and PowerPoint remain indispensable for many users but did not match Outlook’s engagement trajectory.

Ad Spend & Channel Focus: From Social Blitz to Video Precision​

Sensor Tower’s Pathmatics data illuminates a sharp change in Microsoft’s marketing tactics. Early in 2024, Microsoft 365 invested heavily in Facebook and LinkedIn advertising—historically logical channels for B2B growth and brand reinforcement. However, by Q2, spend plummeted and shifted toward targeted desktop video:

• This transition aligns with industry trends: attention spans are migrating from static social content to dynamic video, particularly for business audiences researching software solutions.
• Lower overall spend may suggest growing confidence in brand strength, continued organic reach, or a strategic pause for reallocation in future quarters.

Google Workspace: Collaboration at Scale​

Formerly known as G Suite, Google Workspace maintains a vast—and growing—user base anchored by familiar tools like Google Docs and Google Calendar. The platform’s playbook emphasizes seamless, cloud-native collaboration and real-time document editing.

Audience Trends: Gigantic and Steady​

Google Workspace’s dominance is underscored by staggering site traffic. Docs.google.com saw more than 500 million unique visits each month in Q2 2024, positioning it as the go-to online editor not just for businesses but for students, freelancers, and creators worldwide.

• Google Calendar reliably recorded around 10 million monthly unique web visits, reflecting its entrenchment as a backbone scheduling tool across both professional and personal spheres.

App Engagement: Steady Growth Engine​

Engagement metrics for Google’s productivity apps remain on a gentle upward trajectory:

• Google Calendar’s app saw its monthly active user base rise to roughly 4 million by June, suggesting users increasingly favor mobile-first scheduling.
• Google Docs reported steady growth in app usage, bucking the industry plateau where legacy editors are concerned.

Ad Spend & Channels: The Rise of Desktop Video​

Google Workspace’s Q2 marketing strategy was heavily weighted toward desktop video ads, with monthly spending cresting at $48,000 by June.

• This bullish approach to video suggests the team sees potential in persuasive, contextual content—perhaps how-to demos or customer success stories—more than in banner or search ads.
• The precise effectiveness of this shift is best evaluated in coming quarters, but early indications point to a broader narrative: in B2B SaaS, context-rich video is increasingly central to customer acquisition.

Gmail: The Enduring Engine​

Though often bundled within Google Workspace, Gmail’s scale and impact merit separate consideration. Gmail’s core strength lies in its simplicity, reliability, and integration within the broader Google environment.

Audience Trends: Juggernaut Online​

Gmail’s web portal, mail.google.com, continues to rack up over 9 million unique monthly visits. The monthly deduplicated audience for Gmail overall exceeds 25 million—a figure that puts it well ahead of its main competition when it comes to cross-platform regular use.

• This sustained dominance speaks to Gmail’s universality in both personal and professional communication. Its persistent popularity is reinforced by the lack of credible alternatives at similar scale and with comparable anti-spam and search capabilities.

App Engagement: Gradual Gains​

The Gmail mobile app enjoyed a slow but certifiable climb throughout Q2, ending with more than 9 million monthly active users. This increase is notable given the maturity of the email market and the minimal introduction of radical new features over the past year.

• App engagement’s steady rise may owe itself less to innovation and more to Gmail’s frictionless integration with other Google products (Drive, Meet, Calendar), which keeps users within a single ecosystem.

Ad Spend & Channel Preferences: Organic-First Strategy​

Unlike its peers, Gmail reported no material ad spending in Q2 2024. This reflects a deliberate focus on organic growth, relying on word-of-mouth, search prominence, and deep-rooted user habits to sustain and expand its base.

• The move could be interpreted as a mark of confidence, but it also signals a risk: in a hyper-competitive space, a solely organic strategy may eventually yield ground to ambitious competitors with attention-grabbing campaigns and innovative messaging.

Beyond the Big Three: Strengths, Risks, and Sectoral Trends​

The dominance of Microsoft 365, Google Workspace, and Gmail comes as no surprise; together, the trio represents a near-insurmountable barrier for newcomers and legacy rivals alike. However, even the strongest empires face headwinds and must adapt to stay ahead.

Notable Strengths​

• Integrated Ecosystems: These platforms benefit from seamless integration across applications, reducing friction for end users and IT admins alike. This integration increases stickiness and reduces churn, even as niche challengers emerge.
• Cloud Scale and Security: Both Microsoft and Google leverage enterprise-grade cloud infrastructure, offering uptime, scalability, and data protection that smaller vendors struggle to match or even credibly articulate.
• Network Effects: Users stay because everyone else stays—the prevalence in organizations and educational institutions creates virtuous cycles of collaboration that competitors find difficult to break.
• Innovation Velocity: Especially in the case of Google Workspace, ongoing enhancements—real-time collaboration, AI-powered writing suggestions, activity analytics—keep the platforms feeling fresh even as core features remain consistent.

Potential Risks and Vulnerabilities​

Despite their market dominance, these platforms cannot afford complacency:

• User Fatigue and Feature Overload: As Microsoft 365 and Workspace add features, the complexity barrier rises. Users seeking simplicity may defect to leaner, task-focused platforms such as Notion, Slack, or even newcomers not yet at scale but optimized for mobile and micro-teams.
• Security and Privacy Concerns: Any security lapse (such as a large-scale data breach) would reverberate across the industry, eroding trust and inviting scrutiny from regulators and clients. Both Microsoft and Google have faced advanced persistent threats, and their fortunes hinge in part on their ongoing investments in cybersecurity.
• Platform Lock-In Backlash: The interconnectedness that powers their ecosystem advantage can also breed resentment—particularly as organizations seek more open-source, interoperable solutions to avoid vendor lock-in and unpredictable licensing costs.
• Regulatory Pressure: Ongoing antitrust investigations, especially in the European Union and United States, may precipitate forced unbundling or new restrictions on bundling and data sharing.
• Ad Fatigue and Shifting Attention: Even the best-placed video ads may one day lose ground to new channels or media consumption patterns, reducing efficiency of customer acquisition spend.

Niche Challengers and Market Dynamics​

While Microsoft 365, Google Workspace, and Gmail command outsized attention and deployments, the periphery is alive with experimentation:

• Specialized Collaboration Tools: Products like Slack (now owned by Salesforce), Zoom, Miro, and Trello continue to win in categories—especially in teams frustrated by the slower innovation pace at mega-platforms.
• Open-Source and Privacy-Driven Suites: Offerings such as Nextcloud and the open-source LibreOffice have found favour among privacy-sensitive entities and public sector agencies in Europe.
• AI and Automation: LLM-backed assistants (integrated into Microsoft Copilot or Google Gemini) are gradually changing how users approach routine productivity tasks, but challengers focused on AI-first experiences may soon lure digital-native organizations.

Cross-Platform User Engagement: Key Takeaways​

Analyzing cross-platform user engagement sheds light on business productivity’s new normal—a paradigm where web, desktop, and mobile are not competing, but complementary. The Sensor Tower data reveals that successful brands invest not just in feature expansion, but also in optimizing pathways between web and app experiences.

• Microsoft 365’s cross-platform integration ensures documents, emails, calendars, and sharing tools function the same whether at a PC, via browser, or on a mobile app. This frictionless movement between devices helps retain high-value users.
• Google Workspace’s synchronous collaboration model—where a user can start editing on mobile and finish on desktop, all in real time—proves irresistible in modern hybrid and distributed workplaces.
• Gmail sets the gold standard for consistency: the transition from web to mobile app is essentially invisible to the end user.

Advertising Insights: Spend, Placement, and ROI​

Examining the approach to advertising provides clues about each platform’s maturity and future direction.

• Microsoft 365 moved away from social media bombardment toward more targeted desktop video campaigns. This change aligns with industry research indicating higher conversion rates and recall for contextual, in-feed video over static displays.
• Google Workspace escalated video advertising, outspending Microsoft in Q2 2024, perhaps signaling a belief that video best demonstrates the platform’s collaborative features and drives trial among on-the-fence prospects.
• Gmail’s absence from typical ad channels indicates either a saturation point where paid user acquisition has diminishing returns or a focus on retaining existing users over expanding the base for now.

Sensor Tower Data: Value and Cautions​

Sensor Tower’s analytics provide a peerless window into web and app performance, lending third-party validation to traffic and engagement claims. Yet, there are inherent challenges to bear in mind:

• Deduplicated Audience Caveats: ‘Monthly deduplicated audience’ refers to unique users across platforms, correcting for those who visit via more than one device. While generally reliable, it may underreport users who frequently clear cookies or use privacy tools.
• App Measurement Blind Spots: Certain enterprise accounts, especially those on restricted or firewall-protected networks, may not register in app usage statistics, underestimating true scale.
• Ad Spend Transparency: While Pathmatics provides strong directional insights on ad placements and channels, exact spends aren’t always verifiable and may fluctuate due to last-minute campaign adjustments.

Looking Forward: The Battle for Digital Work​

The enduring leadership of Microsoft 365, Google Workspace, and Gmail in Q2 2024 is both a reflection of their innovation and a prompt for caution. No empire in tech is immune to the “innovator’s dilemma.” For decision-makers, IT buyers, and everyday users, the question is not simply which brand offers the best product mix today—but which is best poised for tomorrow’s workplace realities.
Key signals for the future include:

• AI Integration: With both Microsoft and Google rapidly building LLM-powered features into their suites, the productivity software landscape for the next two years will likely be defined by the speed, cost efficiency, and practical application of AI.
• Greater Openness: The push for open APIs, improved data portability, and cross-suite compatibility is intensifying; vendors that resist may find themselves outflanked, especially in regions with strict regulatory environments.
• Customer-Centric Design: As user fatigue and complexity mount, vendors will need to ensure new features don’t merely check boxes but solve real customer problems. This places a premium on user experience, onboarding, and customer support.
• Security and Privacy Leadership: With the specter of cyberattacks rising, and privacy laws tightening worldwide, brands that can demonstrate proactive, user-centered privacy practices will retain their edge and minimize regulatory risk.

Conclusion: Staying Productive in a Crowded Cloud​

In an era where digital work is inseparable from business success, Microsoft 365, Google Workspace, and Gmail have built ecosystems that drive how millions plan, communicate, and execute. Yet, while their dominance is affirmed by Q2 2024 engagement and audience statistics, the true test lies ahead: adapting at the pace of change, defending against emergent threats, and delighting users amid rising expectations.
Sensor Tower’s meticulously gathered insights reinforce the message: audience loyalty is both hard-won and fragile. Brands that listen, adapt, and invest in both technological innovation and human-centric design will continue to shape the future of work. For professionals charting their organization’s path, keeping a pulse on these shifting platform strategies remains not just recommended, but essential.
