Any day is a good day to learn email segmentation, so we put together this in-depth guide on email segmentation.
We’ll explain what information about your subscribers you need, how to collect it while respecting privacy, and how to adapt your content production flow to create personalized content on a budget. We’ll also share practical tips you can apply right away.
What is email marketing segmentation?
Email marketing segmentation is the practice of dividing your email list into groups based on shared characteristics.
If you’re just starting to build your email list, these characteristics can be as straightforward as age group and location.
As you acquire more subscribers and collect data from sales, you can opt for deeper segmentation. For example, you can check when people open your emails, see which content they interact with, and observe how discounts affect their choices.
By learning your subscribers’ preferences, tracking their behavior over time, and finding patterns, you can segment your email list even more effectively and step up your marketing game.
How segmentation benefits personalization and key email marketing metrics
Email segmentation vs personalization
Segmentation decides who receives an email (groups based on shared traits like behavior, location, or purchase history). Personalization changes what each person sees (name, dynamic product recommendations, personalized offers).
Use segmentation to target the right audience first—then layer personalization to make the message feel 1:1.
Email list segmentation opens the door to data-driven personalization. Personalized content is what brings in benefits like higher open rates, improved click-through rates, higher conversion rates, and better customer retention.
Personalization gets a lot of attention in marketing research, so that the majority of recent studies are focusing exclusively on it rather than on the role of segmentation.
According to a report from Segment Optimizely, 89% of marketing decision-makers consider personalization essential for their business’s success. Another report, this time from Statista, revealed that 62% of the surveyed from various countries claimed that a brand would lose their loyalty if it delivered a non-personalized experience.
At the same time, research shows that customers are increasingly willing to share all types of information with brands in exchange for personalized interactions and exclusive incentives.
So, if you are among those 63% of leaders and marketers who admit that they struggle with personalization, according to Gartner, there is no better time than now to step up your game with segmentation.
Let’s look closer at what you can do with collected customer data to create genuinely personalized content and improve key email marketing metrics.
Segmentation and open rates
Using segmentation data can boost your email open rates. The key is to make your emails feel more valuable at a glance.
To grab subscribers’ attention and spark curiosity, build behavioral triggers into subject lines and preview text. For example, remind them to complete the purchase or mention the products they’ve liked before.
Personalize deals for different groups and address these groups right away. This will help subscribers feel like you are talking to them specifically. Consider taking a step further and including their name.
Segmentation data can help determine when it is best to send emails. Divide your email list based on their location and send your campaigns and communication at the activity peaks for maximum engagement.
These strategies together make it more likely that subscribers will open your emails and see what’s inside.
Segmentation and click-through rates
Email segmentation can improve click-through rates. When recipients feel that the content is relevant and valuable to them, they are more likely to click through and engage further with your email content.
One way to achieve this is through the implementation of dynamic content.
Dynamic content refers to content that changes and adapts based on user interactions, preferences, or other data-driven factors. Common examples are location-specific store sales and events, currency-based discounts, and subscriber-specific recommendations.
Other practices that support higher click-through rates are crafting engaging CTAs and incorporating interactive elements.
Segmentation and conversion rates
Building upon higher click-through rates, segment-based content shows a higher conversion rate.
In this context, a conversion doesn’t always mean an immediate purchase — it can be any desired action. This desired action can be anything from participating in a survey to signing up for a webinar or downloading a free resource.
When you tailor email content to a specific audience, you minimize the risk of overwhelming subscribers with information that doesn’t apply to them. At the same time, you increase the likelihood that the subscribers will take the desired action.
With segmentation data at hand, you can take a step further and set up automated nurturing sequences for different groups. By delivering a series of targeted emails over time, you can guide subscribers through the customer journey and gradually move them towards conversion.
Segmentation and customer retention
As we mentioned earlier, after implementing segmentation, you are likely to experience better customer retention.
Segment-specific offers and promotions make customers feel like valued insiders. Providing exclusive deals based on their preferences or past interactions strengthens their loyalty to your brand and reduces the chance they’ll shop elsewhere.
Once you identify dormant or inactive customers, you can create reactivation campaigns. Encourage them to become active again by addressing their reasons for disengagement, if possible. They may have stopped buying because their favorite product was discontinued. In this case, it’s a good idea to educate them about similar products and offer a small discount to make trying something new more appealing.
Core types of email marketing segmentation
Before we go into the details of how to implement segmentation, let’s discuss the types of email list segmentation and the criteria for forming the groups.
In the B2C and D2C models, there are three main types of email segmentation: demographic, behavioral, and psychographic.
Demographic segmentation answers the question of who your subscriber is and where they live.
Behavioral segmentation is tied to how they interact with your products and services.
Psychographic segmentation is focused on why the subscriber might be interested in your product, what drives their purchase decision, and what values they have.
In B2B, you’ll often add firmographic segmentation (company size, industry, revenue).
In this article, we’ll discuss the most common criteria for segmenting email lists: demographics, purchase history, website activity, website activity, email engagement, and content preferences.
Demographics
Demographic segmentation involves dividing your email list based on demographic factors.
Age, gender, and location are most commonly used as the starting segmentation criteria since these data are the easiest to get. Thank you, Google!
But there are other important factors to consider, like education, income, occupation, and even more granular attributes like generation, culture and religion, marital status, household type, and life stage.
A Gen Z with a multicultural background living with a roommate in New York will likely constitute a different segment from a married millennial or Gen X living in a rented house in Denver. A boomer who is a house owner in Austin might also constitute their own segment.
Since the specific attributes often interact and influence each other, the most effective segmentation strategies consider multiple demographic factors together.
Purchase history
Purchase history is one of the major criteria in behavioral segmentation. The audience gets divided based on their past buying behaviors and interactions with your products or services.
Again, segments can be as general or as specific as you need.
|
Repeat customers First-time buyers |
vs. | Customers who made purchases in the last three months following the link from the email
Customers who shop once a year around spring holidays Customers who buy only discounted products Loyalty program members who buy anything that comes out in a specific product category Customers who made their first purchase through a referral link |
The information you want to look at to create such segments includes recency of purchase, average amount spent, buying full-price or on discounts, buying only specific products or trying different ones each time, seasonality, participation in loyalty programs, and so on.
The collection of these data often requires a robust customer relationship management (CRM) system or an advanced e-commerce platform that can track customer behaviors and interactions, but it’s possible to start off with just a spreadsheet.
Website activity
Website activity is another major criterion in behavioral segmentation. This time, you divide your subscribers into groups based on how they interact with your website.
If a subscriber clicks on a specific product, views it several times, adds it to their cart, or searches for related content in your blog or FAQ section, you can use this information to create tailored email campaigns. However, to capture and use these data in segmentation, you need to integrate your email marketing platform with your website analytics.
The most common use of website activity data is to identify subscribers who abandoned their shopping carts and then send them an email with a reminder or an incentive to complete the purchase.
This tactic is highly effective: according to Statista, in 2024, automated cart abandonment emails demonstrated a click-to-conversion rate of 42%. It means that nearly half of the customers who clicked on the links from these emails returned to the websites and bought the things they had left in the cart. Only welcome emails achieved a higher click-to-conversion rate, scoring at 58%.
Email engagement
Email engagement as a criterion for segmentation is similar to website activity. You divide your email list into different groups based on how subscribers have interacted with your previous email campaigns, including opening, clicking, sharing, and replying.
For example, you might want to separate people who take part in your surveys from those who receive them but never do. The former group will likely be interested to later learn about the results. This is also a good opportunity to thank them with something valuable, like a discount, a coupon, or a piece of relevant information, for example, exclusive insights into how you’re addressing their suggestions.
Regularly clean your email list from time to time from the people that don’t engage to save money on the upkeep costs and have a realistic understanding of how big your email list really is.
Effective email engagement segmentation requires tracking and analyzing subscriber behaviors over time. But some actions can provide immediate segmentation criteria, like joining your email list, for example. Tracking signup dates is useful — you can trigger anniversary offers or milestones.
Content preferences
Content preferences are a criterion in psychographic segmentation. You divide your email list into groups based on the specific interests and preferences that subscribers have expressed.
Such segmentation could be through explicit actions like opting into particular content during the signup process or implicit actions like browsing product pages on your website, checking out tutorials, or clicking on the specific links in your emails.
If you host events, webinars, or workshops, segment your list based on the events subscribers have attended or shown interest in.

However, the best part about interest-based segmentation is that you can just ask your subscribers about what they want or what they want more of. This is a very popular strategy for businesses that are heavily relying on content marketing.

How to implement email marketing segmentation
Now that you’ve learned what email list segmentation is, how you can improve your key email marketing metrics with it, and what criteria you can apply, you might wonder where to start with the implementation.
While specifics might differ depending on your niche and where you are in your business journey, there are steps common for every business.
0. Compliance with regulations
Step zero is compliance with regulations. Since you need to collect and handle personal data, make some time to familiarize yourself with GDPR and the CAN-SPAM Act.
In a nutshell, both documents advocate for transparency and privacy. Make sure to inform your subscribers about the data you’re collecting and how you intend to use it. You should also obtain consent before sending marketing emails and provide clear options for updating their preferences or opting out.
Chicken and egg dilemma — what to do first? Collect the data, see what information is available to you, and then decide on the segments? OR define the criteria first and then decide on the data to collect. There is no right or wrong here. You can do both approaches depending on a specific marketing goal.
1. Collecting customer data
If you decide to collect customer data first and then proceed with segmentation, you need to figure out a way to obtain the specific data that works best for your marketing goals.
Sign-up forms
When subscribers sign up for your emails, use a sign-up form that includes fields for relevant information. It could be basic details like name and email address, and more specific information, such as location, gender, or interests.
B2C and D2C brands tend to use simpler sign-up forms to minimize the friction for potential subscribers and avoid coming across as too nosey.
Some brands even choose not to rush things: they don’t ask anything apart from the email and offer an incentive for coming on board. It’s likely that they will have additional email campaigns planned later on.
In B2B, on the contrary, longer sign-up forms with multiple fields are common. Sign-up forms often appear on pages with valuable content, such as white papers or ebooks, to motivate visitors to take time and answer all the questions. That’s especially the case when visitors have to register first to start receiving newsletters.
Statista is offering more functionality to the users who are willing to provide more information about themselves and how they are intending to use the service.
Preference сenters
Create preference centers where subscribers can manage their preferences. It will allow them to choose the type of content they want to receive, the frequency of emails, and other customization options.
Ideally, users should be able to access their preferences from each email you send.
However, if you don’t have the resources to build a dedicated preference center, there is a workaround — add these settings to your Unsubscribe page. In fact, it’s a common email marketing strategy to make a final attempt to persuade the subscribers to stay on the list.
Surveys and feedback
Send out surveys to your subscribers to learn more about their experiences with your products and services, to find out what expectations they might have, and to learn something that would help you connect with them or meet their needs. The results can provide valuable insights for creating targeted content or reshaping your future marketing campaigns.
Email marketing platforms
Monitor how subscribers engage with your emails. Track open rates, click-through rates, and which links they click on.
In addition, email campaigns provide excellent opportunities for collecting user data with their consent. For example, you can ask subscribers about their birthdays in exchange for a small gift or a discount during their birthday month.
Website analytics
Tools like Google Analytics provide insights into website traffic, user behavior, and demographics. It can help you understand where your visitors come from and what they do on your site. It’s possible to integrate them with your email service provider.
E-commerce platforms
If you’re an e-commerce business, track customer orders, browsing behavior, order history, and product preferences.
Customer Relationship Management (CRM) systems
If you’re using a CRM system, integrate it with your email marketing platform. CRMs often catalog a wide range of data useful for segmentation: demographics, purchase history, behavioral insights, lifecycle stage and lead scoring data, and so much more.
Bear in mind that segmentation is a process that requires an iterative approach. You might not be able to define and implement your segments overnight. That’s why progressive profiling might be a good solution. Gradually collect more data from subscribers over time through subsequent interactions and make sure that the previously collected data is still up to date.
If you don’t know where to start with the tools for collecting and managing customer data, that’s okay. We selected the best B2B email marketing software to make things easier for you. Check it out!
2. Creating customer segments
Now, you might be wondering about the technical aspects of creating customer segments. The good news is that you don’t need to manually send emails to each group of subscribers.
The process can be fully automated, and once set up, it can run for as long as you need it.
Selzy has a simple three-step workflow where you can set criteria for segmentation and even save your choice for the next campaign.
Let’s imagine you are planning a sale similar to the one you ran earlier this year and want to target active US customers who clicked on the links from the emails sent during that campaign. Easy!
And that’s just one example. There are dozens of criteria for you to choose from, and create segments as big or as small as you need them to be.
Start with basic segments and slowly deepen your segmentation. The most important thing is not to get overwhelmed by the myriad of criteria. Don’t overlook the specifics of your business. You might be dealing with a small segment from the beginning, because you have a niche product. In that case, it’s best to focus on the customer journey.
3. Creating targeted content
To systematically create content for different audiences, you need to set up the content production flow. It can be expensive and time-consuming, but there are a few shortcuts that we are happy to share with you:
- Start with alternating only subject lines and slowly build up other personalized content.
- Create uniform templates, ready to be filled up with different products and dynamic content.
- Focus on the content that you can produce once and then use it as many times as you need.
Check out our articles on drip campaigns and wholesale email templates for inspiration.
- Make the most of the content that you already have by making minor changes and resharing it with the new or even the same audience.
- Choose the segment that brings you the most profit and tailor content to their needs first.
- Integrate user-generated content in your email campaigns by inviting subscribers to share their experiences and later featuring their stories.
- Collaborate with partners or complementary businesses to create co-branded content to split production costs.
- Consider integrating AI into your content production flow. You might be surprised by the way it can help you with brainstorming ideas, generating images, and tweaking subject lines.
Remember that effective content doesn’t always require a large budget. Prioritize quality, relevance, and consistency to make the most of your content creation efforts while reducing costs.
4. Testing and measuring results
Effective segmentation comes only with testing and measuring results.
This is where A/B testing can come in handy. Experiment with different subject lines, email formats, and CTAs to see what resonates best with each group.
Many large brands tend to avoid experimenting with email content in their primary markets and, instead, opt for testing in regional markets. However, even if you don’t operate in multiple markets (at least not yet 😉), segmentation can help you test hypotheses without significantly affecting revenue. This is particularly important for e-commerce businesses.
As your subscribers’ preferences and behaviors change, your segmentation strategy should evolve accordingly to remain relevant and continue to bring positive results.
Examples of segmentation-based emails for business of any size
Most brands have a shared vision of what the segmentation-based content should look like. The same email types can be seen throughout multiple email campaigns performed both by big brands and small businesses.
While it all comes down to your creativity and budget size, this basic set trusted by many is a safe choice, especially on the early start. That’s why we’ve picked popular email formats that brands commonly use alongside segmentation.
Location-based campaigns
The best thing about segmentation, based on location, is that your segments can be as big or as small as you need them to be.
Yelp often combines both larger and more granular segments in their email campaigns, leveraging the data they have on where their community members live.
For example, a whole city can be a segment:
Or only a part of it:
For some campaigns, Yelp chooses to target a wider audience, like for this email about growing plants indoors.
While for others, they provide a highly personalized experience through the use of dynamic content:
For emails like the one above, Yelp leverages several segmentation criteria at once: location, website and/or app activity, and the member’s preferences.
To keep providing a personalized experience, Yelp makes sure to remind members to update their preferences, offers to follow more neighborhoods and always leaves them an option to manage their communication settings.
Location might not seem much to work with when you are a small business operating either in one city or one state. However, there is still a potential for connecting with different audiences and catering to your most valuable customers.
While we don’t know whether Sky Frame actually segments their email list, they definitely make the most of being a New York-based business and leveraging other demographic and behavioral data they might have on their customers.
You can follow their lead and launch an additional email campaign for a holiday or a local festival widely celebrated in your area. That kind of information is usually publicly available, and after the campaign, you will learn what part of your email list was particularly active during it. For example, if you have a large part of your email list based in California, add Cinco de Mayo to your email marketing calendar.
Loyalty program and membership levels
Sephora has a three-tier loyalty program called Beauty Insider. The basic tier, Insider, is available for everyone who signs up. Customers who spend $350/year are eligible for the VIB tier, and the ones who spend $1,000/year are assigned to Rouge.
While it might seem quite an effort to manage content production for at least four groups of customers — non-members, Insider, VIB, and Rouge — Sephora uses some of the techniques we mentioned earlier in the article.
For example, they reuse email templates and focus on the subject lines. The primary value comes not from the unique content but from the timing of these emails. Insiders got their email with a selection of mini products six hours earlier than everyone else.
As a part of the loyalty program’s benefits, Sephora hosts special events. They can be aimed at members of every tier or be more exclusive. For example, the event below is meant only for VIB and Rouge members.
Sephora takes into account that not all high-value customers might be able to attend these events, so they segment out those who didn’t show up and follow them up with an email offering a discount for a limited time. The one below is for a different event, but it can still give you an idea.
This set of emails is not by any means exhaustive, but we hope you can draw some inspiration for the loyalty program that would fit your business regardless of its size.
Abandoned cart / Recommendations / Now on sale / Back in stock
A good abandoned cart email can bring back the money that otherwise would be lost. The truth is that people get distracted and forget to complete the purchase, so there is no harm in reminding them.
Many brands take a step further and add recommendations along with the goods left behind.
The example of Drop is particularly interesting since the email combines multiple marketing techniques. The brand sells multiple products, not just mechanical keyboards and accessories, but they make sure that their recommendations directly relate to the item that customers showed their interest in.
Drop creates a sense of urgency by highlighting that the item will remain available only for another 19 days, pushing customers to make up their minds.
Finally, they mention how many recommended items they sold, which may further deepen customers’ trust in Drop’s products.
Retail brands often allow their customers to add items they like to their favorites and set up a notification for when these items go on sale or are being restocked.
Columbia is a good example. They created a universal template and populated it with dynamic content depending on what item customers added to their favorites. They make sure the recommendations are relevant, likely employing AI to make a pick and lure out customers to the website by not immediately revealing the discounted price on the desired item but at the same time showing the range of discounts on similar products in recommendations.
Similar to the one above, the final type of abandoned cart email that we cover today is “back in stock.” Kirkland’s Home notifies customers that the item they were interested in at some point is back and offers an additional 15% off, and not just on the said item but any other of their products. This might indeed help them close more deals than simply reminding customers of the item they searched for.
The best part is you don’t necessarily have to build favorites or back-in-stock functionality into your own website and can just utilize what larger e-commerce platforms and marketplaces have to offer.
Event-based and API-driven email segmentation
Modern email segmentation goes beyond static lists — it responds instantly to real customer actions.
With event-based segmentation, you can trigger targeted email campaigns the moment someone signs up, abandons a cart, makes a purchase, or reaches a key milestone, delivering messages that feel timely, relevant, and personal.
Selzy makes this easy with automation triggers that connect your email campaigns to your website, app, CRM, or e-commerce platform. Turn live customer data into dynamic, high-engagement email sequences that drive conversions — without manual segmentation or constant list updates.
FAQ about implementing email segmentation
What is email segmentation in simple terms?
Email segmentation is the practice of dividing your email list into smaller groups based on shared characteristics, such as location, purchase history, or engagement with past emails, so you can send more relevant emails messages to each group instead of the same email to everyone.
How is email segmentation different from personalization?
Segmentation determines who receives an email, while personalization determines what each recipient sees. For example, segmentation may group subscribers who recently made a purchase, while personalization adds details like their name, product recommendations, or location-specific offers inside the email.
What data do I need to start segmenting my email list?
You can start with very basic data, such as:
- Sign-up date.
- Location or time zone.
- Email engagement (opens and clicks).
As your list grows, you can add purchase history, website activity, content preferences, or survey responses. Segmentation works best when data is collected gradually and with clear user consent.
What are the most effective email segmentation criteria?
The most commonly used and effective criteria include:
- Demographics (location, age group, company type in B2B).
- Behavioral data (purchases, website activity, email engagement).
- Lifecycle stage (new subscriber, active customer, inactive customer).
- Content or product preferences.
Combining multiple criteria usually leads to better results than relying on just one.
How many segments should I have?
There’s no universal number, but fewer is better when starting out. For most small businesses, 2-4 well-defined segments are enough to see meaningful improvements. As you gain more data and confidence, you can create more granular segments without overcomplicating your campaigns.
Is email segmentation compliant with GDPR and other regulations?
Yes, if done correctly. You must clearly inform subscribers about what data you collect, how you use it, and give them control over their preferences. Always obtain consent, allow subscribers to update or remove their data, and avoid collecting information you don’t plan to use.
How do I know if my email segmentation strategy is working?
Track performance per segment, not just overall campaign metrics. Key indicators include:
- Open and click-through rates.
- Conversion or revenue per email.
- Unsubscribe and spam complaint rates.
- Engagement trends over time.
If segmented campaigns consistently outperform non-segmented ones, your strategy is working.
