Digital marketing stands at a critical intersection in 2025. There are more channels than ever to consider when creating an annual marketing plan. Most allocate resources to content marketing, social media, SEO and PPC. Depending on the industry, some may allocate resources to influencer and affiliate marketing, video and webinars. Some find success leveraging SMS marketing and push notifications. Those who are cutting edge are now considering AI and how it impacts every channel.
2025 is the time to rethink email marketing. Email marketing is known for its impressive ROI due to its ability to deliver personalized content tailored to individual preferences and behavior. And, the number of global email users in 2023 was 4.37 billion and was forecasted to grow to 4.89 billion in 2024, reports Statista.
Email can drive conversions and sales more effectively than other marketing channels if done correctly. Today’s digital consumer demands:
- Instant, relevant communication
- Seamless cross-channel experiences
- Meaningful, value-driven interactions
- Minimal friction in engagement
Yet, it’s a crowded space. Statista reports in April 2024, the United States sent the highest number of emails at almost ten billion daily. So, how do you ensure your emails stand out? The traditional email marketing checklist is still valid:
- Use pre-header text
- Keep copy concise
- Give thought to images
- Keep CTAs front and center
- Leave breathing (and clicking) room
- A/B test
- Keep updated on how customers use mobile
A lot has changed, however. To be successful in 2025, discovery and planning are required first, just like any other successful martech program.
Segmentation
First and foremost, consider segmentation. It’s not the 80s anymore. You can no longer win at email by sending the same message to all your subscribers.
At Integrity, we recently helped a higher education institution re-engage their alumni by segmenting emails by the decade the alums graduated and by their major then delivered relevant content. We also helped our retail clients by segmenting emails based on past purchases.
To determine how to segment, it helps to think about available data. Are you using a robust tool like Salesforce that would allow for more complex segmentation? If it’s more of a manual process, marketers can now leverage AI-driven intelligence and machine learning algorithms. Emails are no longer static messages but dynamic, adaptive experiences tailored to individual user behaviors and preferences.
Segmentation should evolve as new data is available. By tracking interactions across channels, zero-party data, and implementing machine learning algorithms, we can build predictive engagement models and create customer profiles. Through continuous learning, segmentation evolves to micro-segmentation and we can continue to refine prediction models and adapt engagement strategies.
List Maintenance
To build your subscriber database while maintaining segmentation, a subscription center is the answer. Give subscribers the option to choose what type of content they want to receive and think about that content from a micro-segment outcome. Likewise, give subscribers the option to opt-out of one segment while remaining in others.
Don’t forget to regularly scrub subscriber lists. If someone hasn’t opened an email in 6 months, move them to a re-engagement list with its own content cadence. If someone has opened emails recently but hasn’t taken the desired action in 6 months to a year (depending on your procurement life cycle), move them to an inactive list with its own content cadence – the first email should be an exclusive offer.
As your segmented lists increase, keep an eye on bounce rates. I once had a company hire my team because their emails were blacklisted during their peak season and they lost a lot of money. Most email clients will call it a soft bounce one or two times then a hard bounce the third time and move the email address to the unsubscribe list. That makes sense, someone may have a legitimate bounce due to an “out of office” message or a temporary email error. If the email bounces after 3 times, they likely have marked you as spam or have changed their email. This new client’s email platform was not automatically managing bounces so an increasing number of emails were repeatedly bouncing. To protect its users, Gmail blacklisted the sender IP so none of this client’s emails were getting inboxed. It took a lot of work, but we eventually got them back in good graces, although a lot of other digital marketing campaigns were needed to offset the drop in email conversions that season.
Hyper-Personalization
Another cutting edge strategy for email marketing in 2025 is hyper-personalization. Personalization has grown way beyond just including the first name in the subject line. With AI, you can generate dynamically personalized content and implement natural language generation for individualized messaging. You can also leverage real-time data: browsing history, location, and device.
Content Strategy
For triggered emails, there are powerful automation tools to help marketers create a multi-stage journey map so that leads can be nurtured through all phases of the customer lifecycle – from onboarding, to engagement, and retention. There are a variety of actions that would trigger an email:
- Behavioral
- Filling out a website form
- Browser abandonment
- Abandoned cart
- Product view follow-up
- Post-purchase recommendations
- Lifecycle
- Welcome
- Onboarding
- Re-engagement campaigns
- Transactional
- Order confirmation
- Shipping notification
- Delivery updates
- Post-purchase follow ups
- Return/exchange communications
- Engagement
- Welcome
- Birthday gifts
- Thanks for referring a friend
Manually scheduled ad hoc emails would be campaigns/promotions or email newsletters and they might contain a redemption coupon, blog post, case study or videos.
To increase your sales funnel, think of ad hoc emails as a testing ground. Send an email to the appropriate segmented subscriber list, then 3-5 days later, review the reports and decide if the email was a winner or not. What was the open, click-through and conversion rates? Were there any booked appointments, closed deals or sold products? When you see a winner, include that in the triggered / automated sequence so when new people take a particular action they receive a winning email. Over time, all triggered / automated emails are winners.
And, with augmented reality on the rise, these types of content will reach new heights in 2025:
- Product visualization
- Allow customers to place the product in their own space or interactive try-on experiences
- Gamification
- AR-based games or challenges within email content
- Virtual tours
- Store walkthrough for retail or tours to help preview experiences before booking for travel companies or event venues
- Video tutorial and usage demonstrations by overlaying AR instructions on product images
Tooling
Many make the mistake of picking a tool first, but all of the components above should be taken into consideration before determining the technology stack. The strategy (even if it is a phased approach) should drive tooling decisions. To win at email marketing in 2025, you will need a combination of advanced CRM systems, AI-driven platforms, and machine learning tools.
For large scale email programs, top platforms include:
Hubspot and Klaviyo are great platforms for a mid-size email marketing program. Even Monday.com is new to the CRM space.
Mobile Optimization
60% of all email opens are on mobile or tablet reports HubSpot via EarthWeb. Likewise, they report 73% of businesses give priority to mobile device optimization. Given the number of devices in 2025, this means responsive design is no longer sufficient. A successful mobile email marketing campaign requires:
- Design fundamentals
- Mobile first templates
- Single column layouts
- Large CTA buttons
- Minimum 14-16pt font size
- Simplified content hierarchy
- Technical optimization
- <50KB file size
- Fast loading images
- Compressed graphics
- Pre-header text optimization
- AMP email compatibility
Scheduling
Once the strategy is in place – you’ve selected the right email marketing platform, created an email or series of emails, tested across browsers and devices and you’ve A/B tested subject lines and pre-headers – you are ready to schedule for deployment.
Over the years, a number of experts have analyzed the best day of week and time of day to send an email. With the growth of smart phones, you would think this would’ve changed over the years as anyone can now easily read an email at any time. In fact, not much has changed since I started managing email marketing teams over 20 years ago. One of my favorite marketers, Neil Patel, just published on LinkedIn as well as on all his social channels and to his email subscribers, that after analyzing 1.46 billion emails sent over a year, data shows that Tuesday, Wednesday and Thursday are the best days to send emails. As for time, 9am to 12pm performed the best.
Sustainability
While the focus of this blog is on successful email marketing strategies defined by ROI, in a world where we all need to think about the environment and how corporate citizenship is valued, the same holds for email. Sustainability in marketing refers to the energy consumption of data centers, transmission and storage emissions, device-level environment costs. There’s a number of ways we can support this:
- Green email design
- Minimize file size
- Remove unnecessary images
- Optimize HTML efficiency
- Use lightweight elements
- Server and infrastructure
- Select green hosting providers
- Select renewable energy data centers
- Select carbon-neutral cloud services
There are email emission calculators, carbon accounting, and benchmarking tools that can be used for comparison. There are also green marketing certifications, industry sustainability guidelines, and third-party environmental verifications that can be obtained and leveraged in marketing to showcase dedication to corporate citizenship.
