1. Global Email User Base

  • 4.6–4.7 billion users:

    • The Radicati Group’s “Email Statistics Report, 2021-2025” projects that the number of worldwide email users will reach approximately 4.6–4.7 billion by 2025, up from 4 billion in 2020.

    • Statista also confirms growth, citing that email remains one of the most universal communication tools, with significant gains in emerging markets (e.g., India, Southeast Asia, parts of Africa).

With billions of users across the globe, email marketing continues to be the connective tissue for digital communications, ensuring broad reach across demographics.

2. Email Marketing ROI (Return on Investment)

  • $38–$45 for every $1 spent:

    • Data & Marketing Association (DMA) studies have historically pegged email ROI in the $36–$42 range. By 2025, industry forecasts push that number closer to $38–$45, fueled by better automation, AI-driven personalization, and more advanced segmentation.

    • A Litmus survey also suggests that 79% of marketers rate email as their top-performing channel in terms of ROI, highlighting that this trend is likely to hold steady or increase.

Email remains unparalleled in cost-effectiveness. As marketing budgets tighten and ROI scrutiny grows, email’s track record for consistent returns makes it a top-tier investment channel.

3. Mobile Email Engagement

  • 50%–60%+ of email opens on mobile:

    • Campaign Monitor indicates that mobile devices already account for around 42–45% of all email opens globally. By 2025, that share is forecast to exceed 50–60%.

    • Adobe notes that millennials and Gen Z in particular prefer to read and respond to emails on their smartphones.

With the majority of email opens shifting to the mobile device, strategies focusing on mobile optimization (i.e., responsive design, concise copy, and clear CTAs) will drive higher engagement rates and conversions.

4. Personalization & Segmentation

  • Over 70% of brands using advanced segmentation:

    • HubSpot’s State of Marketing Report shows that over 61% of marketers already implement some level of email personalization. By 2025, projections suggest the figure could surpass 70% as AI/ML-driven tools become more accessible.

    • Segmenting by behavior (e.g., browsing history, past purchases) and demographic data has been shown to improve email engagement by up to 60%, according to Mailchimp.

Consumers increasingly expect personalized journeys. Tailoring subject lines, offers, and messaging can significantly boost open rates, click-through rates (CTRs), and revenue per email.

5. Interactive Emails on the Rise

  • 1 in 3 marketers will adopt interactive email elements:

    • MarketingProfs notes that interactive email content—like embedded surveys, polls, and rotating image carousels—can increase click-through rates by 20–25%.

    • By 2025, at least one-third of mid-to-large brands are likely to use interactivity as a staple in their email templates, aiming to reduce friction between the inbox and the desired action (e.g., completing a form, making a purchase).

Interactive emails foster higher engagement and can shorten the conversion funnel. Recipients of mobile emails can take action directly within the email, boosting both user experience and measurable outcomes.

6. Automation & AI Integration

  • 60%+ of companies using AI-driven automation:

    • Salesforce’s State of Marketing Report shows a rising trend of AI usage in email marketing: from predictive send times to content generation and lead scoring.

    • By 2025, experts predict that over 60% of mid-sized to large enterprises will embrace AI to power fully automated campaigns, enabling real-time personalization at scale.

AI-driven email campaigns can optimize every touchpoint—sending messages at the “perfect” time, recommending products based on past behavior, and dynamically adjusting content for each user and subscriber segmentation.

7. Privacy & Data Protection Impacts

  • Email open rate metrics less reliable:

    • With Apple’s Mail Privacy Protection gaining traction and similar privacy initiatives from Google and others, open rates are becoming a less accurate measure of success.

    • Gartner advises marketers to shift attention to deeper engagement metrics such as click-through rates, conversions, and zero-party data (information proactively shared by the consumer).

Changes in data privacy regulations (GDPR, CCPA, etc.) require marketers to adopt new metrics for success and explore creative methods (e.g., preference centers, loyalty programs) to collect first-party and zero-party data.

8. Spam & Deliverability Challenges

  • Close to 50% of global email traffic is spam:

    • Securelist and Cisco Talos Intelligence Group track spam traffic volumes, often exceeding 40–50% of daily email traffic. Despite advanced spam filters, spammers continually adapt.

    • Stricter filtering by major ISPs (Gmail, Outlook, Yahoo) means that senders with low engagement, poor list hygiene, or misleading content will see higher bounce rates and lower inbox placements.

Maintaining a strong sender reputation requires continual list cleaning, relevant content, email usage statistics and user engagement. Deliverability can make or break campaign performance—great content doesn’t matter if it never reaches the inbox.

9. Growing Role of Interactive Brand Experiences

  • Email + omnichannel synergy:

    • Omnisend data shows that adding SMS, push notifications, or other channels in tandem with email can increase customer retention by up to 30%.

    • By 2025, even more brands will connect email with chatbots, social media retargeting, and web personalization, focusing on consistent brand experiences regardless of the device or channel.

Email is often the glue that holds omnichannel strategies together, nudging users to return to a cart, check out new products, or participate in loyalty programs across multiple touchpoints.

10. SMBs and Email

  • 80% of SMBs still cite email as a top acquisition channel:

    • According to GetResponse and Mailchimp, small and medium-sized businesses (SMBs) consistently rank email among their most profitable channels.

    • By 2025, that reliance is expected to endure—especially as newer channels (e.g., TikTok, WhatsApp marketing) can be more experimental or less predictable.

Email’s low barrier to entry, high ROI, and flexibility make it the mainstay for smaller businesses with tighter budgets, helping them compete effectively with bigger players.

  1. Artificial Intelligence for Creative Assets: AI isn’t just for timing and segmentation—it’s also increasingly used to generate copy, subject lines, and even visuals, speeding up creative workflows.

  2. Voice-Assistant Optimization: As voice technology grows (think Alexa, Google Assistant), some marketers are exploring ways to make email content more accessible and interactive via voice commands.

  3. Dark Mode Adaptations: With many email clients offering dark mode, marketers need to ensure designs remain visually appealing, accessible, and on-brand for those using dark-mode interfaces.

  4. Hyper-Personalized Videos: Embedding or linking out to short, personalized videos (e.g., “Hi [Name], here’s what’s new for you!”) can dramatically enhance open and click-through rates.

Improve your email marketing efforts

When it comes to email marketing, it’s not just about getting your message across. It’s also about delivering that message promptly. Email subject line statistics for 2024 show that the effectiveness of a subject line can significantly impact consumer engagement with email campaign.

Don’t waste your time and money on poor deliverability and bad campaign results. You can use email marketing tools to send targeted, dynamic emails with the right information at the right time.

To put it simply, there’s no question that email marketing remains an important element to any lead-generation campaign. If you aren’t using it and your competition is, you run the risk of being left behind and falling way behind in the race to acquire new customers.
