The Power of Personalization: How to Use Customer Data to Drive E-commerce Email Success

A guide to leveraging customer data for personalized email campaigns that resonate with subscribers and increase conversion rates.

Introduction: Why Personalization Matters in E-commerce Email Marketing

The modern consumer expects more than just promotional content. They want brands to speak to them personally, catering to their specific needs and preferences. Studies have shown that personalized emails have 26% higher open rates and generate 6x more revenue than non-personalized campaigns. In an e-commerce context, personalization allows you to send targeted messages based on customer behavior, preferences, and purchase history. This drives deeper engagement and creates a better customer experience, resulting in [higher conversion rates](glossary-what-is-a-sign-up-form.html), improved customer retention, and increased revenue.

Take for instance the example of EasyJet. In 2017, the airline sent out emails using 28 data points about customers, including their travel history and preferences, personalizing newsletters with unique travel ideas and deals. This approach generated a 25% higher click-through rate compared to their standard newsletters.


Types of Customer Data to Collect for Personalization

To personalize effectively, you first need to collect the right data. Here are some of the most valuable types of customer data for email marketing:

a. Demographic Data

This includes information like age, gender, location, and occupation. This data can help segment your audience and create tailored offers for specific groups. For example, an online clothing store may send different campaigns to men and women, or promote winter coats to customers in colder climates.

Real-life Example: Nike uses demographic data to send different campaigns for its men’s and women’s collections. During the winter season, customers in colder regions receive emails promoting thermal wear and winter gear.

b. Behavioral Data

Behavioral data involves tracking user actions on your website, such as browsing history, past purchases, or time spent on specific product pages. This allows you to create targeted campaigns based on what customers are actively interested in.

Statistic: According to Barilliance, [personalized product recommendations](transactional-email-best-practices.html) based on behavior can drive 35% of Amazon’s revenue.

c. Transactional Data

This data includes details of past purchases and average order values. It helps in sending timely product recommendations, upsell opportunities, and post-purchase follow-up emails.

Actionable Tip: Use this data to implement upselling tactics. If a customer buys a smartphone, follow up with emails suggesting accessories like cases, chargers, or screen protectors.

d. Psychographic Data

Psychographic data digs deeper into customer motivations, interests, and lifestyle preferences. This data can inform more meaningful engagement by connecting your products to customers' core values or interests.

Example: REI, an outdoor gear retailer, gathers psychographic data to promote adventure travel packages that align with their customers’ love for the outdoors, sustainability, and adventure sports.

e. Engagement Data

Tracking customer interactions with your emails—such as open rates, clicks, and website visits—allows you to gauge interest and improve your email strategy over time.

Statistic: According to Campaign Monitor, segmented email campaigns based on user engagement data can result in a 760% increase in revenue.


Segmentation: The First Step in Personalization

Segmentation is the practice of dividing your email list into smaller, more targeted groups based on specific criteria. This is the foundation of any personalized email campaign because it allows you to deliver content that is more relevant to each segment.

a. Demographic Segmentation

As mentioned earlier, demographics like location, age, or gender can help you create segments. For example, a skincare brand may send anti-aging products to customers over 40 and acne treatments to younger subscribers.

b. Purchase History Segmentation

Segmenting based on purchase history allows you to target customers with relevant product recommendations. For instance, if someone recently bought running shoes, you could promote sports apparel or accessories in follow-up emails.

Example: Stitch Fix, a personal styling service, segments users based on past purchases and behavior, sending them customized clothing recommendations that suit their style preferences.

c. Engagement Level Segmentation

This segmentation targets customers based on how engaged they are with your brand. You can create campaigns for "active" subscribers, such as VIP sales for high-value customers, while offering discounts or incentives to "dormant" subscribers who haven’t purchased in a while.

Example: Amazon is a master of segmentation. Their emails are highly tailored, offering personalized recommendations based on browsing history and past purchases, driving repeat business and increasing cart size.


Behavioral Targeting: Leveraging Actions to Inform Campaigns

Behavioral targeting allows brands to send triggered emails based on specific customer actions. By leveraging behavioral data, you can ensure that your messages are always timely and relevant.

a. Abandoned Cart Emails

One of the most effective forms of behavioral targeting is the abandoned cart email. On average, abandoned cart emails have a 45% open rate, and nearly 21% of them lead to a completed purchase. These emails remind customers of the products they left behind and often include incentives like discounts or free shipping to encourage them to complete their purchase.

Example: A study by SaleCycle revealed that 50% of users who click on abandoned cart emails complete their purchase, highlighting the effectiveness of these reminders.

b. Product Browse Retargeting

If a customer visits a product page multiple times but doesn’t make a purchase, a browse retargeting email can remind them of their interest. These emails can feature the product they viewed, along with complementary or related items.

Actionable Tip: Incorporate product reviews and testimonials into your retargeting emails to build trust and nudge the customer towards making a purchase.

c. Post-Purchase Follow-ups

Send a thank-you email after a purchase, along with product care instructions, usage tips, or recommendations for related products. This helps foster brand loyalty and can lead to repeat purchases.

Example: An online apparel store could trigger a retargeting email to customers who viewed a particular item several times but didn’t purchase. The email might include an offer like, "Complete your look with this item at 10% off!"

Statistic: BigCommerce notes that post-purchase emails can increase the likelihood of repeat buying by 57%.


Dynamic Content: Personalization at Scale

Dynamic content allows you to personalize large-scale campaigns by automatically changing parts of the email based on customer data. For example, you can change product recommendations, greetings, or images based on each recipient’s preferences.

a. Product Recommendations

One of the most common uses of dynamic content is product recommendations. By analyzing past purchases or browsing behavior, you can populate emails with personalized product suggestions for each recipient.

Example: Amazon sends dynamic content emails with personalized product recommendations that are updated in real-time based on customer behavior.

b. Location-Based Content

Dynamic content can also change based on the customer’s geographic location. For example, a travel agency could send tailored vacation deals based on the recipient’s proximity to departure airports or popular local destinations.

Example: Spotify uses dynamic content to create personalized music recommendations, playlists, and concert alerts, making each email highly relevant to the subscriber’s listening habits.

Actionable Tip: Use dynamic content to showcase user-generated content, such as product photos shared by customers on social media, personalized to each recipient’s preferences.


Email Automation and Personalized Workflows

Automation is essential for scaling personalized email marketing. With automated workflows, you can set up trigger-based campaigns that are sent to customers based on their interactions with your website or previous emails.

a. Welcome Series

When a new subscriber joins your list, an automated welcome series is a great way to introduce your brand. This series can include personalized content based on how the customer signed up, such as offering a discount if they signed up through a product page or giving them tips on using your services.

Example: Lyft’s welcome series includes personalized messages and tips to new users, demonstrating how to use the service efficiently and encouraging their first ride.

b. Re-Engagement Campaigns

Automate re-engagement campaigns for inactive subscribers. You can target users who haven’t opened an email or made a purchase in several months with a special offer or ask for feedback to better understand their needs.

Statistic: According to HubSpot, businesses that implement automated retention workflows see a 37% higher customer retention rate compared to those that don’t.

Example: Sephora’s welcome series introduces new subscribers to the brand, offering personalized product suggestions based on their skin type and preferences shared during sign-up.


A/B Testing and Continuous Improvement

Even personalized emails need continuous improvement. A/B testing allows you to optimize subject lines, content, CTAs, and timing to maximize effectiveness.

a. Test Subject Lines

Subject lines are the first thing subscribers see, so testing them is crucial. Experiment with using the recipient’s name, adding urgency, or posing a question to increase open rates.

Actionable Tip: Use A/B tests to find the best time of day to send emails to different segments of your audience.

b. Test Dynamic Content

You can A/B test the performance of different product recommendations or personalized offers to determine which content resonates most with your audience.

Example: You could test whether including the customer’s first name in [the subject line](marine-layer-marketing-confidence.html) increases open rates compared to a more generic greeting like “Hello, valued customer.”

Statistic: Campaign Monitor found that personalized subject lines can increase open rates by 26% on average.


Privacy and Compliance: Safeguarding Customer Data

Personalization depends on customer data, but it’s critical to handle that data responsibly. Privacy laws such as the GDPR and CCPA impose strict regulations on how customer data can be collected and used.

a. Obtaining Consent

Always obtain explicit consent from customers before collecting data. This can be done through clear opt-in forms and by outlining what data will be collected and how it will be used.

b. Data Security

Ensure your systems are secure, and use encryption to protect sensitive customer information. You should also have a clear data retention policy and ensure you’re compliant with local and international privacy laws.

Example: Under the GDPR, businesses must allow users to easily opt-out of data collection or delete their personal information upon request, ensuring transparency and trust.

Actionable Tip: Regularly review your data practices and privacy policies to ensure compliance with evolving regulations and maintain customer trust.

Their emails are highly tailored, offering personalized product recommendations based on a user’s browsing and purchase history. They often send follow-up emails asking for reviews or suggesting complementary products, driving both engagement and sales.

Statistic: Personalized recommendations can drive 35% of Amazon’s total revenue, emphasizing the power of personalization.

b. Netflix: Content Recommendations

Netflix uses viewing history and preferences to send personalized recommendations to users, driving re-engagement with their platform. By focusing on what each user enjoys watching, Netflix keeps its audience engaged and coming back for more.

Example: By leveraging its recommendation engine, Netflix has managed to reduce churn rates, keeping subscribers longer on the platform.

c. Sephora: Tailored Beauty Product Suggestions

Sephora uses data collected during the sign-up process to send personalized product recommendations based on a user’s skin tone, preferences, and previous purchases. This not only increases customer satisfaction but also drives higher conversion rates.

Example: Sephora’s personalized email campaign sees a 70% higher open rate compared to generic email blasts, showing the effectiveness of tailored content.
