10 Must-Have Email Marketing Features Your Business Needs!

However, these impressive results don’t come automatically. The features of email marketing you choose can make or break your campaigns. Despite the fact that 57.8% of marketers report open rates between 20-50%, approximately 50% of all emails still end up in spam folders. Additionally, mobile email opens have increased by up to 30% in recent years, therefore responsive design is no longer optional. We’ve compiled the 10 essential email marketing software features your business needs to stay competitive and maximize ROI in today’s digital landscape.

1. Email Deliverability

The success of your email campaigns hinges on one critical feature: deliverability. If your emails never reach the inbox, you’re essentially throwing money away. According to research, 17.7% of legitimate permission-based marketing emails never make it to the inbox. This means nearly one-fifth of your marketing efforts could be wasted before they even have a chance to perform.

Email Deliverability importance

Email deliverability directly impacts your bottom line. Consider this: if those missed emails performed like your other messages, you’d see a 20% lift in your email marketing ROI. For businesses across the United States, undelivered emails cost approximately $59.5 billion yearly. Even small improvements matter—enhancing your inbox placement by just 1% increases opportunities for engagement and conversions.

Beyond revenue, deliverability affects customer experience. In fact, 78.5% of senders rate the importance of email deliverability between 8-10 on a 10-point scale. The primary benefits of achieving good inbox placement include:

• Reliable customer communication (29.5% of senders)
• Improved customer satisfaction (15.8% of senders)
• Increased revenue from email (approximately 10% of senders)

Email Deliverability tools

Surprisingly, many marketers lack proper deliverability monitoring—61% don’t use inbox placement testing, 76% aren’t monitoring their reputation with Google Postmaster Tools, and 54% don’t actively check major blocklists. Effective monitoring requires specialized tools:

1. Authentication verification tools: Implement and verify SPF, DKIM, and DMARC protocols, which serve as digital signatures proving your emails are legitimate.
2. Reputation monitoring: Services like Sender Score, GlockApps, and MxToolbox track your domain health and sender reputation across major mailbox providers.
3. Testing platforms: Pre-send testing tools like Email Guardian and Litmus help identify potential deliverability issues before campaigns launch.
4. Analytical dashboards: Tools like Deliverability Insights help track volume trends, open rates, and spam complaint rates segmented by mailbox provider.

Email Deliverability best practices

Maintaining strong deliverability requires both technical setup and strategic practices. First, properly authenticate your domain—without authentication, there’s a significant chance your emails will be blocked. Email authentication includes:

• SPF: Prevents unauthorized sending under your domain
• DKIM: Ensures nobody impersonates your domain using encrypted keys
• DMARC: Tells ISPs what to do with emails that fail authentication

List hygiene remains equally crucial. A clean, engaged list is the foundation of good deliverability. This involves:

• Using double opt-in to confirm subscribers’ interest
• Regularly removing inactive subscribers (implement a sunset policy)
• Verifying emails at the point of signup
• Monitoring engagement metrics like opens, clicks, and spam complaints

Furthermore, focus on creating engaging content your audience wants. When recipients interact positively with your emails, mailbox providers learn to deliver your content to the inbox rather than the spam folder. Notably, keeping spam complaint rates below 0.08% is essential, as even lower rates can damage deliverability.

Consequently, the most effective email marketing features include tools that monitor these key deliverability metrics and help you maintain a strong sender reputation through proper authentication, list hygiene, and engagement tracking.

2. Automation Workflows

Automation workflows stand out as one of the most powerful features of email marketing platforms today. These intelligent sequences deliver targeted messages without requiring manual sending for each email, effectively transforming how businesses communicate with their audience.

Automation in email marketing

Automation workflows are a series of emails automatically triggered by specific subscriber actions or predefined criteria. Unlike regular campaigns that blast the same message to everyone simultaneously, automated emails respond directly to individual customer behaviors and needs. These workflows operate continuously—sending personalized messages even while you sleep—based on triggers like signups, purchases, or abandoned carts.

The effectiveness of automation is remarkable—automated emails generate up to 30x more revenue per recipient than one-off campaigns. Moreover, automated emails drive 320% higher revenue than manual emails, making them an essential feature for maximizing ROI.

Benefits of automation workflows

The advantages of implementing automation workflows extend beyond just revenue generation:

• Improved efficiency: Once created, workflows run on autopilot, freeing your team to focus on other critical tasks. Instead of sending individual emails to thousands of contacts, you can design one effective workflow that handles communication automatically.
• Enhanced personalization: Because automated emails are triggered by specific actions, they deliver highly relevant content precisely when subscribers need it. This timely, targeted approach results in 8x higher open rates than standard campaigns.
• Better customer experience: Automated emails create consistent, personalized journeys for each subscriber. From welcoming new contacts to celebrating purchase anniversaries, these timely interactions build stronger relationships and improve satisfaction.
• Increased conversions: Companies using automation see 53% more conversions, primarily because messages arrive at moments of peak interest. For instance, abandoned cart emails average $3.65 revenue per recipient—compared to just $0.11 for standard campaigns.
• Optimized costs: Email automation reduces expenses by maximizing the impact of existing content and templates while minimizing manual effort. With an average ROI of $36 for every $1 spent, automation delivers exceptional value.
• Improved data utilization: Automation turns customer data into actionable insights, enabling better segmentation and more targeted messaging. This strategic approach ensures your communications remain relevant throughout the customer lifecycle.

Examples of automation triggers

Effective automation starts with the right triggers—events that initiate your workflow. The most powerful examples include:

1. Behavioral triggers: Actions taken by subscribers, such as:
   • Completing a signup form (welcome series)
   • Abandoning a shopping cart (recovery emails)
   • Viewing specific products (browse abandonment)
   • Purchasing a product (post-purchase series)
   • Clicking specific links in emails (interest-based content)
2. Time-based triggers: Calendar-driven events that include:
   • Birthdays and anniversaries
   • Subscription renewal dates
   • Replenishment reminders for consumable products
   • Membership expiration notices
   • Inactivity periods (re-engagement campaigns)
3. Demographic triggers: Profile-based information such as:
   • Location (geo-targeted offers)
   • Customer segment (VIP communications)
   • Customer lifecycle stage (nurture sequences)

For each trigger type, email marketing platforms provide customizable templates and workflows. Welcome series typically generate $2.65 per recipient, while cart abandonment flows achieve the highest ROI among all automations. Well-designed post-purchase emails maintain an impressive 61.68% open rate, demonstrating why these automation features deserve priority status in your email marketing toolkit.

3. Personalization and Dynamic Content

Personalized email content represents one of the most valuable features of email marketing that significantly boosts campaign performance. With 80% of customers more likely to purchase from brands offering personalized experiences, this capability has become essential rather than optional for modern marketing teams.

Dynamic content in email marketing

Dynamic content refers to email elements that change based on subscriber data, preferences, and behaviors. Unlike static emails where everyone receives identical messages, dynamic content creates tailored experiences for each recipient. This versatile feature allows marketers to personalize:

• Email subject lines and body text
• Product recommendations and imagery
• Calls-to-action and promotions
• Entire email layouts and designs

The technology works through automated content blocks within email design tools that adapt a master template to each subscriber. Depending on your objective, dynamic content can utilize various data types:

• User Data: Names, locations, preferences, purchase history
• Behavioral Data: Website activity, email clicks, abandoned carts
• Contextual Data: Time, weather, device type
• Third-Party Data: Demographic or industry-specific information

Personalization strategies

Effective personalization begins with solid audience segmentation. Marketers can customize messages based on several factors:

1. Demographics: Age, gender, location, education level, and occupation enable basic personalization. For instance, brands like Adidas have increased engagement by showing menswear to male subscribers while displaying womenswear to female subscribers.
2. Behavioral Triggers: Past purchasing history, website activity, and email engagement provide powerful personalization opportunities. Birchbox effectively uses this approach by tracking when customers begin checkout but don’t complete purchases, automatically sending reminder emails with images of abandoned items.
3. Psychographics: Tailoring messages based on subscriber beliefs, values, and interests creates deeper connections. This approach allows messages to align with customer lifestyles and preferences.
4. Real-Time Elements: Incorporating countdown timers for flash sales, weather-based product recommendations, or live social media feeds keeps content fresh and timely. UK hospitality brand icelolly.com saw a 35% higher open rate and 201% increase in click-through rate by displaying searched and abandoned deals.

Impact on engagement

The effects of personalization on campaign performance are substantial. Personalized emails produce 6x higher transaction rates compared to generic messages. Other impressive statistics include:

• Emails with personalized subject lines achieve 50% higher open rates
• Dynamic name personalization can drive a 15% increase in click-through rates, 7% increase in conversion rates, and 37% rise in sales
• Personalized emails generate up to 30x more revenue per recipient than standard campaigns

Personalization particularly excels at specific campaign types. Abandoned cart emails with dynamic content average $3.65 revenue per recipient versus just $0.11 for standard campaigns. Similarly, when ByLaurenJean upgraded a static email about diamond rings with a dynamic live poll, they saw a 53% higher click-through rate.

Beyond immediate metrics, personalization improves deliverability since email engagement signals like opens, clicks, replies, and forwards help inbox service providers determine whether messages reach the inbox or spam folder. As first-party data becomes increasingly important with the decline of third-party cookies, dynamic content offers an effective way to gather valuable customer insights.

Overall, among key features of email marketing automation, personalization stands out as particularly effective at creating memorable customer experiences that drive measurable business results.

4. Drag-and-Drop Email Builder

Creating visually appealing emails is a critical feature of email marketing that many businesses struggle with without the right tools. Drag-and-drop email builders have emerged as the solution, slashing production times while requiring minimal technical skills.

Features of drag-and-drop builders

Drag-and-drop email builders come packed with capabilities that streamline the email creation process:

• Pre-designed templates – Access to diverse template libraries provides a springboard for creativity, enabling fresh campaigns without constant designer input.
• Content blocks and modules – Reusable content elements that can be saved and applied across multiple campaigns for brand consistency.
• Responsive design tools – Features that automatically optimize emails for various devices, ensuring they look great on desktop monitors and mobile phones alike.
• Image editing capabilities – Built-in tools that eliminate the need for separate image editing software.
• Preview functionality – Device-specific preview options to check how emails will appear across different platforms.

Many builders also include AI assistants for content generation, making it even easier to craft engaging emails without extensive design skills.

Ease of use for non-tech users

One of the most valuable aspects of these builders is their accessibility to marketers without coding experience:

Drag-and-drop email builders eliminate the need for HTML knowledge, allowing anyone to create professional-looking emails. The interface is intentionally intuitive, enabling users to pull images and modules into place within the email design. This approach enables marketers to craft visually appealing emails with ease, saving both time and resources.

Additionally, these tools often offer online availability with autosave functionality, allowing users to return to templates and edit them anytime. This feature proves especially useful for teams working collaboratively on email campaigns.

Indeed, the time efficiency provided by these builders is substantial. What once required a dedicated designer can now be accomplished by marketing team members themselves, freeing up resources for other initiatives. According to Beefree, 81% of users create emails at least 3 times faster with their drag-and-drop builder.

Customization options

Beyond basic design capabilities, modern drag-and-drop builders offer extensive customization options:

• Personalization tokens – Send customized emails at scale by inserting recipient-specific information.
• Brand consistency tools – Features that help maintain visual identity through consistent colors, fonts, and styles.
• Custom HTML options – Advanced editors that allow for granular customization through custom code when needed.
• Modular design approaches – Systems that encourage streamlined design processes through selecting and assembling various blocks like headers, content sections, and call-to-actions.

Subsequently, these customization options enable marketers to tailor emails to exact specifications. Some platforms even offer customization at granular levels with features like custom HTML blocks and rich image libraries.

For brands with consistent messaging, the ability to create, save, and reuse custom content blocks is invaluable, speeding up creation processes while ensuring brand consistency across all communications.

Eventually, these email builders deliver measurable business results. According to Beefree, 64% of their users increased their click-through rates by 11% or more after implementing their drag-and-drop builder.

5. Mobile Optimization

Mobile email usage has skyrocketed, with 43% of all emails now opened on mobile devices compared to just 19.4% on desktops and 36.1% on webmail clients. This shift makes mobile optimization an indispensable feature of email marketing that can dramatically impact campaign performance.

Why mobile optimization matters

The consequences of ignoring mobile optimization are severe. A staggering 45% of consumers unsubscribe from promotional emails that don’t work well on smartphones. Furthermore, 42.3% of email users simply delete non-optimized emails. Poor mobile experiences don’t just cost you the current sale—they can permanently damage your sender reputation.

Mobile-friendly email campaigns generate tangible results:

• 15% increase in unique mobile clicks
• 40% higher click-to-open rates for responsive emails
• 6x higher transaction rates compared to non-optimized messages

Given that mobile users typically make decisions within seconds, optimizing your emails for smaller screens is crucial for maintaining subscriber engagement and preventing frustration.

Responsive design features

Responsive email design automatically adapts your email’s layout based on the device it’s viewed on. Unlike static designs, responsive emails use CSS media queries to adjust content dynamically. This approach ensures your messages remain readable and visually appealing regardless of screen size.

Key responsive design elements include:

• Fluid layouts: Content that automatically adjusts to different screen widths
• Single-column format: Simplifies vertical scrolling and prevents awkward horizontal movement
• Touch-friendly buttons: Minimum size of 44×44 pixels (Apple) or 48×48 pixels (Google)
• Scalable images: Automatically resize to fit the screen without distortion
• Adaptable fonts: Minimum 14px for body text and 22px for headlines for optimal readability

Mobile-first email strategies

Currently, the most effective approach is designing for mobile first, then adapting for larger screens. Mobile-first strategies include:

Optimize preview text and subject lines. Subject lines should remain under 40 characters to prevent truncation on mobile screens. Preview text (up to 90 characters on iOS) offers a powerful opportunity to capture attention before the email is opened.

Embrace white space. Proper spacing between paragraphs, links, and buttons provides “breathing room” that makes content scannable and prevents accidental clicks. This is particularly important for touchscreen navigation.

Minimize email size. Smaller emails mean faster load times, greater accessibility, and better deliverability. Compress images and keep overall email weight under 100KB whenever possible.

Test across multiple devices. What looks perfect on one device might appear broken on another. Preview your emails on various platforms before sending to ensure consistent display across the device spectrum.

6. Advanced Reporting and Analytics

Basic dashboards are no longer enough. The strongest email marketing platform features now surface insights in real-time and translate raw metrics into action you can take today.

• Full-funnel visibility. Modern dashboards link opens, clicks, on-site behaviour and revenue in one view, so you can spot drop-offs instantly. GetResponse’s 2024 benchmark study, for instance, shows average open rates jumping to 39.64% and CTRs to 3.2%—but only brands that track those lifts can react fast enough to capitalize on them.
  
• Predictive & AI-driven forecasting. With 88 % of marketers already using AI in daily workflows, leading platforms layer machine-learning models over your historical data to forecast conversions, flag at-risk segments and even suggest the next best offer.
  
• Cohort and deliverability drill-downs. Break performance out by domain, device, segment or send-time to see why one audience buys and another bounces.
  
• Multi-touch attribution. Tie email influence to PPC, social and offline sales to defend your budget at the next board meeting.
  
• Automated insight notifications. Instead of combing through reports, get Slack or email alerts when KPIs spike or sink beyond set thresholds.
  

When your analytics suite answers the “so what?” in seconds, optimisation stops being a quarterly task and becomes a habit baked into every send.

7. A/B Testing and Optimisation Tools

If you can’t test, you can’t grow. Built-in split-testing is therefore a non-negotiable email marketing platform feature:

• Element-level tests (subject lines, CTAs, creative, send times) let you iterate without creating a brand-new campaign each time.
  
• Case studies regularly show double-digit lifts. One CRO analysis calculated a 40 % conversion uplift from a single two-week A/B test—worth an extra $10 000 in incremental revenue.
  
• Enterprise suites should also offer multivariate testing and automatic winner-selection so the highest-performing version rolls out to the rest of your list automatically.

8. Segmentation and List-Management

Spray-and-pray broadcasting is dead. Robust segmentation engines are the feature most correlated with revenue lifts:

• Segmented campaigns can drive a 760 % increase in revenue over non-segmented blasts.
  
• Look for visual segment builders that stack demographic, behavioural and predictive filters (e.g., “VIPs + Viewed-but-not-bought in last 7 days”).
  
• Hygiene automations—double-opt-in, automated re-engagement, sunset policies—keep lists clean and boost deliverability.

9. CRM & Third-Party Integrations

Email doesn’t live in a vacuum. Best-in-class platforms sync bi-directionally with CRMs, ecommerce carts and ad networks:

• Organisations with tight sales/marketing alignment generate 208 % more marketing revenue and enjoy 38 % higher sales-win rates. brainstormclub.com
  
• Deep integrations unlock behaviour-based triggers (e.g., “quote created in Salesforce → nurture sequence”) and unify reporting.
  
• Open APIs matter; you’ll inevitably need to connect niche tools down the road.

10. Compliance & Security

Privacy regulation is only heading one way—stricter. Make sure your platform bakes compliance into its core email marketing platform features:

• Security extras—S/MIME or TLS encryption, role-based access controls and single-sign-on—protect both customer data and your reputation.remains essential for maintaining strong customer relationships regardless of which solution you select.
• GDPR, CAN-SPAM, CASL and CCPA tooling for consent capture, data-subject requests and audit trails.
• Non-compliance is expensive: GDPR fines can reach €20 million or 4 % of global turnover, and LinkedIn was hit with a €310 million penalty in 2024 for improper data use. brevo.com
