How Many Emails Are Sent Per Day in 2024 and Beyond: An Exhaustive Guide for Understanding and Optimizing Email Usage

Email is the lifeblood of digital communication. Over 347 billion work and personal emails shoot back and forth daily as of 2023. And that flood of email traffic only looks to intensify in the coming years as worldwide email users inch closer to the 4.5 billion mark.

But how many of those 347 billion daily emails represent critical business communications or productivity-enhancing coordination? And which countries and demographics rely most heavily on email to conduct their professional and personal affairs?

This comprehensive data-driven guide provides an exhaustive look at the current and future state of global email traffic. Read on for unprecedented insight into email usage trends, engagements metrics, and best practices that empower enterprises and individuals alike to maximize their email potential.

Projected Number of Email Users and Traffic Volume Through 2026

Email isn‘t going anywhere. As of 2022, email boasts over 4 billion users globally according to The Radicati Group. That represents stunning market penetration, with email serving over half the total worldwide population.

And after a slight pandemic-related dip in 2020, email regained momentum with user growth up nearly 2.7% year-over-year as of 2023. Email continues to successfully adapt to mobile devices and changing consumer preferences. Its efficiency and utility make it a digital communication bedrock that no platform can match.

With the expanding user base comes an exponential rise in emails firing off daily across the globe:

• 2017 – 269 billion
• 2018 – 281.1 billion
• 2019 – 293.6 billion
• 2020 – 306.4 billion
• 2021 – 319.6 billion
• 2022 – 333.2 billion
• 2023 – 347.3 billion
• 2024 – 361.6 billion (projected)
• 2025 – 376.4 billion (projected)
• 2026 – 392.5 billion (projected)

Email volume has steadily risen approximately 4-6% annually in recent years aside from the 2020 Covid outlier. Analysts project continued increases in emails sent and delivered daily through at least 2026 as usage spreads.

Breaking Down Business vs. Personal Email Volume

With over 300 billion emails shooting back and forth daily in 2024, what proportion represent business communications versus personal correspondence?

Per data analysis by Lifewire, around 106.4 billion emails sent per day cater specifically to business needs. The remaining 220 billion+ daily emails enable personal uses like social coordination and direct communication between friends, family, groups, and more.

Clearly workplace communication still accounts for a sizeable chunk of global email traffic at over 30%. But the vast majority of emails facilitate the vital personal connections that underpin people‘s daily lives in 2024 – enabling them to share moments, plan events, exchange ideas and information, and nurture relationships efficiently.

Email‘s flexibility enables it to support professional team productivity and global business just as adeptly as close friend communication despite social media encroachment.

Email Client Usage and Engagement Share

Inbox overload plagues most email users. So which email platforms actually dominate the landscape in 2024?

According to Statista data, below were the global email client market share percentages as of October 2022:

• Gmail – 31.44%
• Outlook – 13.95%
• Yahoo mail – 5.05%
• QQ mail – 4.01%
• Edison Webmail – 2.86%
• Apple Mail – 2.26%
• Others (AOL, GMX etc.) – 40.44%

Gmail continues its supremacy with nearly one in three emails routed through Google‘s platform. But niche providers like China‘s QQ and Edison mail enjoy strong regional support as well.

Armed with awareness around market share, senders can tailor email campaigns that play to the typical configurations of major inboxes. Factoring mobile versus desktop usage is also key…

Mobile on the Rise for Email Access

Email underwent rapid adaptation for smartphone screens. And users increasingly access inboxes on the go compared to sitting at a desk.

Campaign Monitor crunched the numbers across studies: Globally around 52% of email opens occurred on mobile devices as of 2021. That figure reaches an even split at times in technologically progressive markets like North America.

Crafting emails optimized for mobile displays grows more crucial by the year. Marketers who lag on responsive design get left behind as audiences flock to smartphones.

Granular Look at Email Engagement Metrics and Benchmarks

So people rely on email round the clock via browsers and mobile apps. But how frequently do they actually open and click those newsletters, promotions, or personal missives?

Thanks to sophisticated tracking software, senders can monitor email program performance down to precise open and click rates. Software company HubSpot aggregated key benchmarks across industries:

• Average email open rate: 21.33%
• Average email click-through rate: 2.9%
• Top 10% of email click-through rates: 5.31%+

So for every 100 emails delivered, around 21 get opened and engage with email content directly. Of those, roughly 3 then click through to linked sites for additional info or special offers contained in the message.

Advanced marketers constantly test and tweak their email approach to push toward top tier open and click-through rates. Tactics like careful list segmentation, timing adjustments, mobile optimizations, and attention-grabbing (but not spammy) subject lines make every percentage point count.

Business Email Traffic Peaks Midweek

Intuition says Friday happy hours might dampen workplace email productivity. But aggregated data reveals that business-related email engagement actually peaks midweek instead.

According to SuperOffice analysis, Tuesday sees the highest business email volume at over 6% of weekly traffic. Engagement then remains strong on Wednesday and Thursday before trailing off toward the weekend.

Likewise, the most productive business email sending times are Tuesday through Thursday from 8-10 AM, 12-1 PM, and 1-3 PM. Late night or early morning emails tend to languish. Factor common working hours and engagement patterns into critical communication timing for optimal results.

Curating Email Subscription Lists Effectively

Growth hacking mentality pervades modern marketing: more signups and bigger lists rule…right?

Wrong actually. Quality trumps quantity for email lists to ensure high deliverability and engagement over time. Here are quick best practices when building an email subscription base:

• Incentivize opt-ins to align truly interested segments
• Limit purchased or rented email lists which may feature disengaged accounts
• Prune consistently inactive subscribers via automation
• Segment recipients carefully by preferences and attributes
• Target engaged subsets for key communications vs blasting all
• Share useful content that aligns with subscriber needs

Keep email lists tidy, segmented, and truly opt-in based on interests. That helps nurture higher lifetime engagement as opposed to inflating vanity metrics.

The Future of Email: Staying Power Despite Social Buzz

In an age increasingly dominated by flashy social media apps, messaging platforms, and digital interaction innovation, email manages to persist as the communications bedrock for enterprises and individuals alike worldwide.

Email has successfully adapted to mobile contexts and quick-hit interactions while retaining the core efficiency that makes it timeless. And as the ongoing deluge of global daily emails illustrates, rumors of email‘s demise have been greatly exaggerated even among tech pundits.

Moving forward, analysts foresee email client usage holding strong even as messaging platforms rise and niche email alternatives enter some markets. Here are two surprising email trends predicted in the 2022 Radicati Future View report:

• Consumer email users will reach over 3.1 billion by 2026
• The preferred client will be webmail as Gmail claims over 40% market share

Meanwhile, business email use will drive much of the growth:

• Business emails sent/received per user will top 140 per day by 2026, up 46% from 2022
• Total business emails sent daily will blow past 205 billion by 2026

So while social media grabs headlines with flashy new features, email works humbly behind the scenes to weave the fabric of digital communications connecting the planet. Email will continue filling that role for enterprises and individuals through 2023 and beyond.

Key Takeaways and Action Items for Email Dominance

Email stands the test of time by enabling speedy communication, vital documentation, and relationship building between businesses, groups, and individuals globally. Take advantage by internalizing these core lessons:

• Email usage and volume grows consistently year over year still
• Ensure emails display properly on mobile devices that dominate access
• Monitor open and click-through rates to fine-tune email performance
• Time business emails smartly midweek when engagement peaks
• Build email lists thoughtfully based on quality over quantity

Take a cue from worldwide emailing trends by being judicious and strategic with inbox communications for workplace needs or personal connections alike. Treat recipient time and attention with care.

Then watch open rates rise and relationship opportunities unfold thanks to email‘s unique magic. Even with over 300 billion emails flooding the digital landscape daily in 2024, a well crafted message can still make all the difference.
