The numbers behind why email still outperforms nearly every other channel, refreshed for 2026 and the years ahead.
by Isabella Torres · Last updated: 2026-07-06Email marketing still delivers roughly $36 for every $1 spent, reaches more than 4.6 billion users worldwide, and moves about 361 billion messages a day. Those figures, refreshed for 2026, confirm what this email marketing statistics projection has shown for years: email remains the highest return channel most businesses own outright.
This guide replaces our older snapshot with current numbers, cleaner benchmarks, and forward projections through 2027. It is built for marketers who want to defend budget, set realistic targets, and decide where email fits in a wider mix.
Every figure below reflects widely reported industry data rather than a single vendor claim, so you can use it in a plan, a pitch deck, or a board update with confidence.

Key Takeaways
The headline numbers are reach, return, and volume. Email now reaches more than 4.6 billion users, returns roughly $36 per $1 spent on average, and carries about 361 billion messages every day. Those three metrics explain why email keeps its place at the center of most marketing programs.
Volume is a double edged signal. High daily throughput proves the channel is trusted, but it also means the average inbox is crowded, so relevance and timing decide whether a campaign is opened or ignored. The winners are not the senders with the largest lists, they are the senders with the most segmented and consented ones. For a fuller view of how these fundamentals fit together, our overview of 7 Surprising Email Marketing Statistics for 2023 pairs well with the current figures here.
Independent compilations, including the widely cited email marketing statistics compiled by HubSpot, place reach and return in the same ballpark year after year, which is why these figures are safe to anchor a plan around.

More than 4.6 billion people use email today, and that base is expected to keep climbing toward 4.9 billion later this decade. That scale matters because email is a permanent, portable identity: unlike a social follower, an email address travels with the user across devices, jobs, and platforms.
Usage is also frequent rather than occasional. A large share of users check email several times a day, and most report using it at least once a week for shopping, work, and account notifications. That habit is what makes email dependable for both promotional sends and critical transactional messages.
Mobile is now the default reading surface, with the majority of opens happening on phones. Rendering quality on small screens directly affects clicks, which is why mobile-first design has moved from a nice extra to a baseline requirement. If you build lists and campaigns the right way, you own an audience no algorithm can throttle, a point our guide to email marketing software unpacks in practical steps.
The average return on email marketing is about $36 for every $1 spent, and top performing programs report considerably more. No other widely used channel combines this level of return with such low fixed cost, which is why email remains a budget favorite even in tighter years.
The reason is structural. Email carries almost no media cost, so once your platform and content are in place, each additional send is nearly free. Returns compound as your list grows and your segmentation sharpens, meaning the same infrastructure produces better results over time without a proportional rise in spend.
Automated flows carry the strongest numbers. Welcome sequences, cart recovery, and post purchase series consistently outperform one off broadcasts because they hit users at the moment of intent. Deliverability underpins all of it: if messages land in spam, ROI collapses regardless of how good the copy is, a theme covered in depth by email deliverability research from Litmus.
Focus on five core metrics: open rate, click-through rate, bounce rate, unsubscribe rate, and conversion rate. Treat them as ranges rather than single targets, because industry, list quality, and send frequency all shift the numbers. The table below shows the bands most healthy programs fall within.
| Metric | Typical range | What it signals |
|---|---|---|
| Open rate | 20% to 40% | Subject line and sender trust |
| Click-through rate | 2% to 5% | Content and offer relevance |
| Bounce rate | Under 2% | List hygiene and validation |
| Unsubscribe rate | Under 0.5% | Frequency and expectation fit |
| Conversion rate | 1% to 5% | Overall campaign effectiveness |
Note that open rates have become a softer signal since privacy protections began pre-loading images, which can inflate reported opens. Because of that, clicks and conversions now deserve more weight when you judge real engagement. Welcome emails remain the standout: they routinely post the highest open and click rates of any message type, so investing in that first send pays off quickly.
Projections point up, not down. The global email marketing software market is expected to approach $17.9 billion by 2027, and total email users are forecast to keep rising through the end of the decade. Far from being replaced, email is being reinforced as the connective layer between websites, apps, and every other channel.
Three shifts define the next few years. First, automation and behavioral triggers are becoming the default, not the exception. Second, privacy changes are pushing programs toward first party data and explicit consent. Third, personalization is moving beyond a first name in the subject line toward genuinely tailored content based on real behavior.
The practical takeaway is that spending on email is not a defensive holding pattern, it is an investment in a growing channel. Businesses that build clean lists, automate the obvious flows, and measure clicks over vanity opens will be positioned to capture that growth rather than watch it pass.
Statistics only matter if you can turn them into sends. Mailsoftly gives you list segmentation, automated flows, and clear reporting so you can chase the $36 return rather than just read about it. You start free, then scale as your list grows, with transparent pricing at every tier.
Pricing is straightforward (as of 2026-04-15). The Free plan covers 500 contacts and 2,000 emails per month with no credit card. Paid plans add capacity as you grow, so your cost tracks your results instead of guessing at a huge upfront tier.
| Plan | Annual price | Contacts | Emails / month |
|---|---|---|---|
| Free | $0 | 500 | 2,000 |
| Basic | $39/mo | 5,000 | 40,000 |

| Premium | $159/mo | 30,000 | 300,000 |
| Enterprise | Custom | Unlimited | Unlimited |
Free hands-on migration means moving an existing list is not a barrier, and human support is there when a campaign needs a second set of eyes. The point is simple: the statistics reward action, and the tooling should make action easy rather than technical.

Yes. Email still returns roughly $36 for every $1 spent and reaches more than 4.6 billion users, keeping it among the highest return marketing channels available. Its effectiveness comes from low cost, direct reach, and an audience you own rather than rent from a platform.
A healthy open rate typically falls between 20% and 40%, depending on your industry and list quality. Because privacy features can inflate reported opens, treat clicks and conversions as more reliable indicators of real engagement.
The global email marketing software market is projected to approach $17.9 billion by 2027, with steady growth expected beyond that. Rising user counts and heavier investment in automation are the main drivers behind the forecast.
Prioritize click-through rate and conversion rate, since they reflect real action rather than a passive impression. Support them with bounce rate and unsubscribe rate to monitor list health and frequency fit over time.
Generally yes. Triggered flows such as welcome series and cart recovery reach users at the moment of intent, so they consistently post higher open, click, and conversion rates than one off broadcasts. That is why automation is the single highest leverage investment in most programs.
