What Is Email Marketing Segmentation? A Complete Beginner's Guide

Email marketing segmentation is the process of dividing an email list into smaller groups of subscribers based on shared characteristics, interests, actions, or other relevant information.

Instead of sending exactly the same email to every subscriber, businesses can use segmentation to deliver messages that are more relevant to different groups of people.

What Is Email Marketing Segmentation?

Email marketing segmentation is the practice of dividing an email subscriber list into smaller groups according to information that is useful for marketing communication.

These groups are commonly called segments.

For example, an online store might have separate segments for new subscribers, existing customers, frequent buyers, and subscribers who have shown interest in a particular product category.

Each segment can receive communication that is appropriate for its situation or interests.

Why Is Email Segmentation Important?

Subscribers are not all the same. They can have different needs, interests, levels of engagement, and relationships with a business.

Segmentation helps marketers recognize these differences and create more relevant communication.

1. It Can Improve Relevance

A segmented email campaign can focus on information that is more closely related to the recipient's interests.

2. It Supports Better Customer Communication

New subscribers may need educational information, while existing customers may need product updates, support information, or recommendations.

3. It Supports Personalization

Segmentation provides a foundation for personalized email experiences. Marketers can tailor content based on information they have appropriately collected about subscribers.

4. It Works Well With Automation

Segments can be used as conditions or audiences in automated email workflows.

5. It Can Reduce Irrelevant Messages

Sending every campaign to every subscriber can result in unnecessary messages. Segmentation can help businesses send appropriate campaigns to appropriate audiences.

How Does Email Segmentation Work?

Email segmentation generally follows a simple process:

1. Collect appropriate subscriber information.
2. Identify meaningful differences between subscribers.
3. Create groups based on those differences.
4. Prepare content for each relevant group.
5. Send the appropriate campaign to each segment.
6. Measure engagement and improve the strategy.

The exact process depends on the email marketing platform and the data available to the business.

Common Types of Email Segmentation

There are many ways to segment an email list. The appropriate method depends on the business model, audience, available data, and marketing objective.

Demographic Segmentation

Demographic segmentation groups subscribers according to relevant demographic information.

Depending on the business and the information legitimately collected, this might include factors such as:

• Age group
• Job role
• Industry
• Company size
• Language preference

Demographic information should only be collected and used when it has a clear and legitimate purpose for the communication.

Interest-Based Segmentation

Interest-based segmentation groups subscribers according to topics, products, services, or subjects they have indicated an interest in.

Behavioral Segmentation

Behavioral segmentation uses subscriber actions to create meaningful groups.

Examples include subscribers who:

• Opened a particular email.
• Clicked a specific link.
• Downloaded a resource.
• Visited a particular page.
• Purchased a product.
• Started but did not complete an action.

Behavioral data can be particularly useful because it reflects what a subscriber actually did rather than only what they reported about themselves.

Customer Status Segmentation

Businesses can separate subscribers according to their relationship with the company.

Engagement-Based Segmentation

Engagement segmentation groups subscribers according to how actively they interact with emails.

A business might distinguish between highly engaged, moderately engaged, and inactive subscribers.

This can help marketers avoid treating an inactive subscriber exactly like someone who regularly interacts with campaigns.

Location-Based Segmentation

Location-based segmentation groups subscribers according to relevant geographic information.

It can be useful when businesses operate across different regions, countries, or time zones.

Possible uses include:

• Regional promotions
• Local events
• Time-zone appropriate sending
• Region-specific information
• Language-specific communication

Email Segmentation Examples

Example 1: Online Clothing Store

An online clothing store could create segments based on product categories that customers have shown interest in.

Customers interested in men's running shoes could receive relevant product education or new-product information instead of campaigns focused on unrelated categories.

Example 2: Software Company

A software company might separate free users, trial users, and paying customers.

Each group can receive communication appropriate to its stage in the customer journey.

Example 3: Educational Website

An educational website might allow subscribers to choose subjects they want to learn.

Subscribers can then receive articles and resources related to their selected subjects.

How to Create Email Segments

Step 1: Define Your Goal

Start by deciding why you need segmentation.

For example, you might want to improve educational content relevance, create different onboarding journeys, or communicate with customers based on their interests.

Step 2: Identify Useful Data

Determine which information can meaningfully support your goal.

Avoid collecting large amounts of information simply because it is technically possible.

Step 3: Create Meaningful Segments

Create groups that have a clear purpose.

A segment should help you make a meaningful communication decision.

Step 4: Prepare Relevant Content

Create content that matches the needs or interests of the segment.

Step 5: Test Your Campaign

Check that the correct subscribers are included and that the message matches the intended audience.

Step 6: Measure Results

Review appropriate email marketing metrics and use the results to improve future campaigns.

Segmentation and Email Automation

Segmentation and automation work well together.

A segment can determine who receives an automated workflow, while subscriber actions can also cause people to enter or leave particular groups.

Segmentation and Personalization

Segmentation and personalization are related but they are not exactly the same thing.

Segmentation groups subscribers into categories.

Personalization adapts content or messaging for an individual subscriber or a particular audience using available information.

For example, a business could create a segment for customers interested in running shoes and then personalize an email using the customer's name or relevant product information.

Common Email Segmentation Mistakes

1. Creating Too Many Segments

Excessive segmentation can make campaigns difficult to manage and may provide little additional value.

2. Using Irrelevant Data

Information should have a meaningful connection to the communication strategy.

3. Ignoring Data Quality

Incorrect or outdated subscriber information can lead to poor targeting.

4. Sending the Same Message to Every Segment

If every segment receives exactly the same communication, the benefit of creating the segments may be limited.

5. Over-Personalizing

Personalization should be useful and appropriate. Using information in ways subscribers do not expect can reduce trust.

6. Forgetting Inactive Subscribers

Engagement should be monitored over time. Inactive subscribers may need a different communication strategy from highly engaged subscribers.

Email Segmentation Best Practices

• Start with a clear business or communication objective.
• Collect only useful and appropriate information.
• Keep segments simple enough to manage.
• Use behavior and interests when they are relevant.
• Review and update segments regularly.
• Match content to each segment.
• Respect subscriber expectations.
• Test campaigns before sending them.
• Monitor engagement and campaign performance.
• Protect subscriber information and follow applicable privacy requirements.
