1. Introduction to Audience Segmentation and Targeted Email Campaigns
Email marketing is an important digital marketing channel that helps businesses communicate with potential customers, existing customers, subscribers, and other audiences. However, sending the same email to every subscriber may not meet everyone's interests, needs, or expectations. Audience segmentation helps marketers divide an email list into smaller groups so they can deliver more relevant messages.
Targeted email campaigns use information about each group to create suitable content, offers, recommendations, and calls to action. For example, an online training institute may send beginner-level course information to new learners, advanced training details to experienced professionals, and placement preparation updates to students who have completed a course.
When segmentation is planned carefully, businesses can improve the relevance of their communication, build stronger customer relationships, and evaluate campaign performance more effectively.
Learning Objectives
- Understand the meaning and importance of audience segmentation.
- Learn the difference between segmentation, personalization, and targeting.
- Explore common methods of segmenting an email audience.
- Understand how to create and manage audience segments.
- Learn how to plan and execute targeted email campaigns.
- Identify useful email marketing metrics and optimization techniques.

2. What Is Audience Segmentation?
Audience segmentation is the process of dividing a larger audience into smaller groups based on shared characteristics, interests, preferences, actions, or needs. In email marketing, these groups are created from subscriber information and engagement data.
Each segment can receive email content designed for its particular requirements. Rather than treating every subscriber identically, marketers use segmentation to make communication more useful and relevant.
Example of Audience Segmentation
Suppose an online education company has 10,000 email subscribers. Instead of sending every subscriber the same promotional email, the company may organize them into groups such as:
- New subscribers who have recently registered.
- People interested in web development courses.
- People interested in digital marketing courses.
- Students who have enrolled in a course.
- Past students interested in advanced training.
- Subscribers who have not interacted with recent emails.
Each group can receive information that matches its interests and relationship with the company.
Key Characteristics of Effective Segmentation
- Relevant: The segment is connected to a meaningful marketing objective.
- Measurable: The marketer can estimate its size and evaluate its performance.
- Actionable: The business can create suitable content for the group.
- Manageable: The segment is practical to maintain and use.
- Privacy-conscious: The data is collected and used appropriately.
3. What Are Targeted Email Campaigns?
A targeted email campaign is an email marketing activity designed for a particular audience segment. The campaign's message, offer, timing, and call to action are selected according to the needs or behavior of that group.
Targeted campaigns can be promotional, educational, transactional, relationship-building, or designed to encourage a specific action.

4. Why Audience Segmentation Is Important
4.1 Improves Message Relevance
Subscribers have different needs and interests. Segmentation helps marketers deliver messages that are more closely related to what each group wants to learn, purchase, or accomplish.
4.2 Supports Better Engagement
When email content matches the recipient's interests, the recipient may be more likely to read it, click a link, or take another useful action. Engagement should be measured using several metrics rather than relying on opens alone.
4.3 Helps Increase Conversions
A targeted campaign can guide subscribers toward an appropriate next step. For example, someone who has requested a course brochure may need curriculum details, while someone who has already enrolled may benefit more from onboarding information.
4.4 Reduces Irrelevant Communication
Segmentation can reduce the number of unrelated promotions subscribers receive. This may help improve the customer experience and reduce avoidable unsubscribes or spam complaints.
4.5 Improves Marketing Efficiency
Marketers can prioritize campaigns according to audience needs, campaign goals, and available resources instead of creating one generic message for every subscriber.
4.6 Supports Customer Retention
Existing customers can receive helpful product guidance, educational resources, loyalty benefits, and relevant follow-up communication. These messages can support long-term customer relationships.
4.7 Enables More Meaningful Reporting
Segment-level reporting helps marketers compare performance across audience groups. They can identify which messages, offers, or customer journeys are producing useful results.
5. Audience Segmentation vs. Personalization vs. Targeting
These terms are related but describe different activities in email marketing.
| Concept |
Meaning |
Example |
| Audience segmentation |
Dividing subscribers into groups using shared criteria. |
Creating a segment for subscribers interested in SEO. |
| Targeting |
Selecting the audience that should receive a particular campaign. |
Sending an SEO webinar invitation to the SEO-interest segment. |
| Personalization |
Customizing an email for a recipient or group. |
Using a subscriber's name or displaying relevant course information. |
| Automation |
Sending messages automatically when predefined conditions or events occur. |
Sending a welcome email after someone subscribes. |
Important: Segmentation identifies the audience, targeting selects who receives the campaign, personalization adapts the content, and automation determines when or under what conditions a message is sent.
6. Main Types of Audience Segmentation
6.1 Demographic Segmentation
Demographic segmentation groups subscribers according to relevant characteristics such as age range, education level, occupation, job title, or company size. Marketers should collect only the information needed for a legitimate purpose.
Example: A professional training company may create different email journeys for university students, working professionals, and business owners.
Best use cases: Education, career training, B2B marketing, and services designed for specific professional groups.
6.2 Geographic Segmentation
Geographic segmentation organizes subscribers according to location, region, country, city, or time zone when this information is relevant to the campaign.
Example: A business may send event invitations to subscribers in the city where the event will take place.
Best use cases: Local promotions, regional events, location-specific services, and time-zone-aware scheduling.
6.3 Behavioral Segmentation
Behavioral segmentation uses actions taken by subscribers or customers. These actions may include purchases, website visits, product views, downloads, course inquiries, or clicks on specific links.
Examples:
- Subscribers who downloaded an SEO guide.
- Customers who purchased a particular product.
- Visitors who requested a course brochure.
- Customers who have purchased more than once.
- Subscribers who clicked a webinar registration link.
Behavioral data can indicate what a subscriber is interested in, but marketers should avoid treating every action as proof of purchase intent.
6.4 Psychographic Segmentation
Psychographic segmentation groups people according to interests, preferences, values, motivations, or lifestyle characteristics when such information is voluntarily provided or appropriately obtained.
Example: A learning platform may distinguish subscribers interested in career advancement from those who want to develop a personal project.
Best use cases: Educational content, interest-based newsletters, hobbies, lifestyle products, and community communication.
6.5 Engagement-Based Segmentation
This method groups subscribers according to how they interact with email campaigns.
- Highly engaged: Subscribers who regularly click or respond to relevant emails.
- Moderately engaged: Subscribers who interact occasionally.
- Low engagement: Subscribers who have shown little recent interaction.
- Inactive: Subscribers with no meaningful interaction over a defined period.
Engagement definitions should be based on the email platform's available data. Open tracking can be unreliable because some email clients use privacy features or automated image loading. Clicks, conversions, replies, and other meaningful actions can provide additional evidence.
6.6 Purchase-Based Segmentation
Purchase-based segmentation organizes customers using relevant purchase information, such as products purchased, order frequency, recency, order value, or product category.
Examples:
- First-time customers.
- Repeat customers.
- Customers interested in a particular product category.
- Customers who have not purchased recently.
- Customers eligible for a relevant accessory or complementary product.
Use purchase information responsibly and ensure that promotions do not contradict a customer's preferences or applicable marketing permissions.
6.7 Lifecycle-Based Segmentation
Lifecycle segmentation groups subscribers according to their relationship with the business.
| Lifecycle Stage |
Audience Situation |
Suitable Email |
| Awareness |
Person has recently discovered the brand. |
Introductory information and useful resources. |
| Interest |
Person has shown interest in a topic or product. |
Educational content and relevant details. |
| Consideration |
Person is comparing available options. |
FAQs, comparisons, case studies, or course curriculum. |
| Conversion |
Person is ready to take an action. |
Clear registration, purchase, or booking information. |
| Onboarding |
Person has recently purchased or enrolled. |
Getting-started instructions and support resources. |
| Retention |
Existing customer continues using the product or service. |
Helpful tips, updates, and relevant next steps. |
| Re-engagement |
Previously active subscriber has become inactive. |
Useful updates or a preference-confirmation message. |
6.8 Interest-Based Segmentation
Interest-based segmentation uses preferences that subscribers select, such as topics they want to learn about, product categories they prefer, or the type of newsletter they want to receive.
Example: A digital marketing newsletter may allow subscribers to select SEO, social media marketing, paid advertising, content marketing, or email marketing.
6.9 Source-Based Segmentation
Source-based segmentation groups subscribers according to where they joined the email list or which campaign introduced them to the brand.
Possible sources include website signup forms, webinars, course demo registrations, downloadable guides, in-person events, or specific landing pages.
Example: Subscribers who registered for a digital marketing webinar may receive follow-up resources related to that webinar.
6.10 B2B and B2C Segmentation
B2B segmentation focuses on business customers, organizations, professional roles, company size, industry, or business needs.
B2C segmentation focuses on individual consumers, their interests, preferences, shopping behavior, and customer journey.
The appropriate method depends on the product, audience, business model, and information the organization can responsibly use.
7. Choosing the Right Segmentation Criteria
Not every available data point should become a segment. Choose criteria that help answer a specific marketing question.
Questions to Ask Before Creating a Segment
- What is the objective of the campaign?
- Which audience is most likely to find the message useful?
- What information can reliably identify that audience?
- Was the information collected and retained appropriately?
- Can the business create content relevant to this group?
- How will success be measured?
- Does the segment need exclusions to prevent conflicting messages?
Example of Matching Goals to Segments
| Marketing Goal |
Possible Segment Rule |
Campaign |
| Increase webinar registrations |
Subscribed contacts who selected the webinar topic and have not registered. |
Webinar invitation. |
| Encourage course inquiries |
Subscribers who requested related information but have not submitted an inquiry. |
Course details and FAQ email. |
| Increase repeat purchases |
Customers with a previous purchase and an appropriate related offer. |
Relevant complementary product email. |
| Re-engage inactive contacts |
Subscribed contacts with no meaningful engagement over a defined period. |
Preference update or re-engagement email. |
| Improve onboarding |
New customers or students who have not completed a key onboarding step. |
Getting-started guide. |
8. Collecting and Organizing Audience Data
Effective segmentation depends on accurate, useful, and responsibly collected data. Marketers should not collect unnecessary personal information merely because an email platform supports it.
8.1 Signup Forms
Signup forms can collect an email address and, when appropriate, a small number of optional preferences. For example, a newsletter signup form may ask which digital marketing topics the subscriber wants to receive.
8.2 Surveys and Preference Centers
Surveys and preference centers allow subscribers to communicate their interests directly. A preference center may let users select newsletter topics, choose email frequency, or update their contact information.
8.3 Website and Landing Page Activity
When tracking is appropriately disclosed and permitted, website activity can help identify broad interests. For example, a subscriber who requests an SEO guide may be interested in receiving related SEO resources.
8.4 Customer Relationship Management Systems
A CRM system stores customer and prospect information, such as inquiries, interactions, purchases, and lifecycle stages. When integrated correctly with an email platform, it can support more accurate segments and coordinated customer communication.
8.5 Email Marketing Platforms
Email platforms commonly provide contact fields, tags, groups, saved segments, campaign reports, and automation rules. The exact features depend on the platform and subscription plan.
8.6 Data Quality Practices
- Use consistent field names and values.
- Validate email addresses when collecting them.
- Remove or suppress invalid and unsubscribed contacts as required.
- Record consent and subscription status accurately.
- Correct outdated or duplicate records.
- Restrict access to personal information.
- Review segments periodically to ensure their conditions remain useful.
9. Lists, Tags, Groups, and Segments
Email marketing platforms may provide several ways to organize contacts. Although the exact terminology differs by platform, the underlying concepts are similar.
| Feature |
Purpose |
Example |
| Audience or list |
Stores contacts and their subscription information. |
Newsletter subscribers. |
| Tag |
Labels a contact with a useful attribute. |
Interested in SEO. |
| Group or preference |
Records a subscriber's selected interest or category. |
Social media marketing. |
| Segment |
Defines a group of contacts who match specified conditions. |
Subscribed contacts interested in SEO who have not registered for a webinar. |
Example of Segment Conditions
A marketer wants to invite subscribers to an SEO webinar. The segment could use conditions such as:
- Subscription status is subscribed.
- Interest is SEO or related search marketing topics.
- Webinar registration has not occurred.
- The subscriber is not suppressed from marketing communication.
The marketer should review the resulting recipients before sending the campaign and confirm that the rules match the intended audience.
10. Creating an Audience Segment Step by Step
Step 1: Define the Campaign Goal
Begin with a clear goal, such as increasing webinar registrations, introducing a new service, encouraging course inquiries, or improving customer retention.
Step 2: Identify the Relevant Audience
Decide which subscribers would benefit from the message. Avoid selecting people simply because their data is available.
Step 3: Select the Data Criteria
Choose criteria such as topic preference, lifecycle stage, recent behavior, purchase history, or email engagement. Use reliable data that is appropriate for the campaign.
Step 4: Create the Segment Rules
Set the conditions in the email platform. Depending on the platform, conditions may be combined using AND or OR logic.
- AND: Every specified condition must be true.
- OR: At least one specified condition must be true.
Example using AND: A contact is subscribed AND interested in SEO AND has not registered for the webinar.
Example using OR: A contact selected SEO OR content marketing as an interest.
Step 5: Preview the Segment
Review the matching contacts and estimate the segment size. Check for missing fields, outdated information, accidental exclusions, and duplicate records.
Step 6: Apply Exclusions
Exclude people who should not receive the campaign, such as unsubscribed contacts, already registered participants, or customers who have already completed the relevant action.
Step 7: Save and Name the Segment
Use descriptive names that explain the audience and purpose. For example, SEO Webinar - Subscribed - Not Registered.
Step 8: Prepare the Campaign
Create an email with a relevant subject line, useful content, a clear call to action, and appropriate links.
Step 9: Test Before Sending
Check the recipient list, personalization fields, links, display on mobile devices, sender details, and unsubscribe mechanism. Send a test email to verify the final result.
Step 10: Measure and Improve
Evaluate clicks, registrations, conversions, unsubscribes, and other goal-related metrics. Use the results to improve the segment and campaign.
11. Planning a Targeted Email Campaign
A successful targeted campaign requires more than selecting a segment. Marketers must align the audience, message, timing, and desired action.
11.1 Set a SMART Goal
A SMART goal is specific, measurable, achievable, relevant, and time-bound.
Example: Increase registrations for an upcoming webinar among subscribed contacts interested in SEO over the next two weeks.
11.2 Define the Target Audience
Describe the audience in practical terms. Include the relevant interest or lifecycle stage, the campaign's purpose, and the conditions that make someone eligible to receive the email.
11.3 Develop the Message
Match the content to the audience's needs. A new subscriber may need an introduction, a prospective customer may need more information, and an existing customer may need instructions or a relevant next step.
11.4 Create a Relevant Subject Line
Write a concise and accurate subject line that clearly reflects the email's content. Avoid exaggerated claims, misleading urgency, and promises that the message does not fulfill.
11.5 Write a Clear Call to Action
Use one primary call to action where practical. Examples include “Register for the Webinar,” “Explore the Course,” “Download the Guide,” and “Update Your Preferences.”
11.6 Choose the Sending Time
Consider the audience's time zone, campaign purpose, and previous performance. Test different sending times where appropriate rather than assuming that one schedule works for every audience.
11.7 Review and Launch
Confirm the recipient rules, permissions, email content, links, tracking settings, and suppression rules before launching the campaign.
12. Examples of Targeted Email Campaigns
Example 1: Digital Marketing Course Inquiry
Audience: Subscribed contacts who requested information about digital marketing training.
Goal: Encourage interested learners to explore course details.
Subject: Explore the Digital Marketing Course Curriculum
Email Content:
Hello,
Thank you for your interest in digital marketing. Explore topics such as SEO, content marketing, social media, paid advertising, email marketing, and campaign analytics to understand how these skills support modern marketing activities.
Review the course details to learn more about the topics covered and decide whether the program matches your learning goals.
CTA: Explore the Digital Marketing Course
Why it works: The message is connected to the subscriber's expressed interest and provides a clear next step without making unsupported promises.
Example 2: Webinar Invitation
Audience: Subscribed contacts who selected SEO as an interest and have not registered for the webinar.
Goal: Increase relevant webinar registrations.
Subject: Learn Practical SEO Fundamentals in Our Upcoming Webinar
Email Content:
Hello,
Would you like to strengthen your understanding of search engine optimization? Join our upcoming webinar to explore keyword research, on-page SEO, technical SEO, and ways to measure performance.
Review the event details and register if the session matches your interests.
CTA: Register for the Webinar
Why it works: The topic matches the audience's selected interest and gives readers a clear reason to take action.
Example 3: Re-Engagement Email
Audience: Subscribed contacts who have not shown meaningful engagement over a defined period.
Goal: Learn whether subscribers still want to receive updates.
Subject: Would You Like to Keep Receiving Our Updates?
Email Content:
Hello,
We want to make sure our emails remain useful to you. You can update your preferences to choose the topics you would like to receive, or unsubscribe if our updates are no longer relevant.
CTA: Update Your Preferences
Why it works: It respects the subscriber's choice instead of repeatedly sending unrelated promotions.
Example 4: Existing Customer Campaign
Audience: Customers who purchased an introductory course and have shown interest in further learning.
Goal: Encourage exploration of a relevant advanced learning option.
Subject: Explore Your Next Learning Opportunity
Email Content:
Hello,
As you continue developing your skills, you may want to explore training that builds on what you have already learned. Review the available topics and choose a learning path that suits your current goals.
CTA: Explore Advanced Courses
Why it works: The recommendation is connected to the customer's learning journey rather than being a generic promotion.
13. Personalization in Targeted Campaigns
Personalization complements segmentation by adapting elements of an email to a subscriber's preferences or relevant information.
Common Personalization Methods
- Name personalization: Use a subscriber's first name when it is available and accurate.
- Interest personalization: Show content related to selected interests.
- Behavior-based content: Share resources related to a recent, relevant interaction.
- Lifecycle personalization: Adapt content for new subscribers, customers, or returning learners.
- Preference-based content: Use the topics and email frequency a subscriber selected.
- Location-aware information: Provide relevant local event information when location use is appropriate.
Using Dynamic Fields Safely
Email platforms may support dynamic fields or merge tags. For example, a template may use a placeholder such as {{first_name}} to insert a contact's first name.
Dynamic fields should be tested carefully. If a name is missing, the email should display a suitable fallback greeting rather than an empty field or visible placeholder.
Example: If the subscriber's name is available, the greeting may say “Hello, Priya.” If the name is unavailable, it may say “Hello there.” The precise syntax depends on the email platform.
Personalization Best Practices
- Use only accurate information relevant to the email.
- Do not reveal sensitive details unnecessarily.
- Make sure dynamic content displays correctly on mobile and desktop.
- Provide fallback text for missing data.
- Explain preferences and data use clearly where appropriate.
- Allow subscribers to update preferences and opt out of marketing emails.
14. Email Automation and Segmentation
Email automation sends messages according to predefined events, conditions, or schedules. Segmentation helps determine which contacts qualify for a particular automated journey.
| Automation |
Trigger or Condition |
Purpose |
| Welcome sequence |
A person subscribes. |
Introduce the brand and set expectations. |
| Lead nurturing |
A subscriber requests a guide or course details. |
Provide relevant educational information. |
| Event reminders |
A subscriber registers for an event. |
Share event information and reminders. |
| Customer onboarding |
A purchase or enrollment is completed. |
Explain the next steps. |
| Post-purchase follow-up |
A customer completes a purchase. |
Share relevant instructions or support resources. |
| Re-engagement |
A subscribed contact meets inactivity criteria. |
Ask whether the subscriber wants to continue receiving emails. |
Example of an Automated Journey
- A visitor subscribes to receive digital marketing resources.
- The visitor receives a welcome email.
- The subscriber selects SEO as an interest.
- The email platform places the subscriber in an SEO-interest segment.
- The subscriber receives relevant SEO resources.
- If the subscriber registers for an SEO webinar, the system excludes them from further invitations to that same webinar and sends appropriate event information.
- After the event, the subscriber may receive follow-up resources according to their preferences and the campaign's permissions.
15. A/B Testing for Targeted Email Campaigns
A/B testing compares two versions of an email element to understand which version performs better for a defined objective. Testing can help improve subject lines, content, calls to action, offers, and sending times.
Elements That Can Be Tested
- Subject line wording.
- Preview text.
- Email headline.
- Call-to-action text.
- Content length or layout.
- Offer presentation.
- Sending time.
Example of an A/B Test
| Version A |
Version B |
Purpose |
| Explore Our SEO Guide |
Learn the Basics of SEO |
Compare subject-line approaches. |
| Download the Guide |
Get Your SEO Checklist |
Compare call-to-action wording. |
A/B Testing Process
- Choose one clear objective.
- Select one variable to test.
- Divide an appropriate audience into comparable test groups.
- Keep other important campaign elements consistent.
- Choose a success metric before launching the test.
- Allow enough time and data for a useful comparison.
- Review the results and apply the learning cautiously.
Do not assume that a small difference proves one version is better. Sample size, audience composition, timing, privacy-related tracking limitations, and external factors can affect results.
16. Measuring Targeted Email Campaign Performance
Campaign performance should be measured against its objective. A campaign intended to generate registrations should be evaluated primarily on registrations and related conversion measures, not just email opens.
| Metric |
Meaning |
Why It Matters |
| Delivery rate |
Percentage of sent messages accepted for delivery. |
Helps assess delivery performance. |
| Bounce rate |
Percentage of sent emails that could not be delivered. |
Highlights invalid addresses or delivery problems. |
| Open rate |
Percentage of delivered emails recorded as opened by the platform. |
Can provide directional information, but tracking may be affected by privacy features. |
| Click-through rate (CTR) |
Percentage of delivered emails that generated at least one tracked click, according to the platform's definition. |
Measures interaction with email links. |
| Conversion rate |
Percentage of a defined audience that completed the desired action. |
Measures campaign outcomes. |
| Unsubscribe rate |
Percentage of recipients who unsubscribed after the campaign. |
Can indicate audience or content mismatch. |
| Spam complaint rate |
Rate at which recipients reported the email as spam. |
Helps monitor recipient dissatisfaction and sender reputation. |
| Revenue per email |
Attributed revenue divided by the defined number of emails sent or delivered. |
Helps assess commercial performance. |
Common Performance Formulas
Click-through rate (CTR):
CTR = (Unique Clicks ÷ Delivered Emails) × 100
Conversion rate:
Conversion Rate = (Attributed Conversions ÷ Defined Audience or Delivered Emails) × 100
Bounce rate:
Bounce Rate = (Bounced Emails ÷ Emails Sent) × 100
Unsubscribe rate:
Unsubscribe Rate = (Unsubscribes ÷ Defined Delivered Audience) × 100
Use consistent denominator definitions when comparing campaigns because email platforms may calculate metrics differently.
Example Calculation
Suppose a campaign is delivered to 2,000 subscribers, receives 160 unique clicks, and produces 24 registrations.
- CTR = (160 ÷ 2,000) × 100 = 8%.
- Conversion rate using delivered emails = (24 ÷ 2,000) × 100 = 1.2%.
- Click-to-conversion rate = (24 ÷ 160) × 100 = 15%.
These figures help marketers understand how many recipients interacted with the email and how many completed the intended action. They should be interpreted in context, not as universal benchmarks.
17. Common Audience Segmentation Mistakes
17.1 Sending the Same Email to Everyone
Problem: The email may contain irrelevant content for many subscribers.
Solution: Start with a few meaningful segments based on interests, lifecycle stage, or behavior.
17.2 Creating Too Many Small Segments
Problem: Excessive segmentation can make campaign creation and reporting difficult, while very small groups may not provide reliable test results.
Solution: Prioritize segments that have a clear purpose and enough audience volume to justify separate treatment.
17.3 Using Incorrect or Outdated Data
Problem: Subscribers may receive messages based on inaccurate interests or old customer information.
Solution: Validate data, maintain consistent fields, and review segment rules regularly.
17.4 Ignoring Subscription Status
Problem: A campaign may include contacts who have unsubscribed or are not eligible for marketing messages.
Solution: Apply the platform's suppression and consent rules before sending.
17.5 Forgetting Exclusion Rules
Problem: Subscribers may receive repeated invitations after they have already registered or receive offers that no longer apply.
Solution: Exclude people who have already completed the campaign's goal or are otherwise ineligible.
17.6 Over-Personalizing
Problem: Unexpected use of personal information can make an email feel intrusive.
Solution: Personalize only when it is relevant, proportionate, and consistent with the subscriber's expectations.
17.7 Measuring Only Open Rates
Problem: Opens may be affected by privacy protections and automated activity.
Solution: Track clicks, registrations, purchases, replies, and other meaningful actions that relate to the campaign goal.
17.8 Sending Too Many Emails
Problem: Excessive or repetitive communication may cause fatigue and unsubscribes.
Solution: Coordinate campaign schedules, respect frequency preferences, and avoid sending multiple overlapping campaigns unnecessarily.
18. Privacy, Consent, and Responsible Email Marketing
Audience segmentation depends on subscriber information, so privacy and permission must be considered throughout the process. Marketing requirements vary by jurisdiction, audience, and message type. Businesses should follow applicable laws and platform requirements.
Best Practices
- Collect email addresses through appropriate and transparent methods.
- Explain what subscribers are signing up to receive.
- Record and respect marketing preferences and consent where required.
- Do not use purchased or scraped lists as a substitute for appropriate permission.
- Use personal information only for legitimate, disclosed purposes.
- Provide a clear and functional unsubscribe mechanism for marketing emails.
- Maintain suppression lists so opted-out contacts are not accidentally re-added to campaigns.
- Secure audience data and limit access to authorized people.
- Review retention practices and remove data when it is no longer needed, subject to applicable obligations.
- Check relevant legal and platform requirements before launching a campaign.
Important: Having someone's email address does not automatically mean that person has agreed to receive marketing. Follow applicable consent and communication rules.
