What is email personalization?

Email personalization is a strategy to add a personal touch to emails based on the recipient's behavior and interaction history. By segmenting your audience based on different traits, you can design emails specific to a group of people.

For example, if a set of people checked out similar items during a holiday, using AI tools, you can use this data to send emails highlighting those items. Besides, you can also add recommendations based on those items to nudge them to buy.

Why should you make your emails personalized?

Here are some of the reasons why you should be prioritizing email personalization:

• Audience demands personalization

  • 60% of consumers say they will likely become repeat buyers after a personalized shopping experience with a retailer. - Segment, The State of Personalization 2021

  • When an email lacks personalization, 52% of customers say they will choose a different place to shop. - Activetrail

  • 70% of millennials are frustrated with brands sending irrelevant emails. - SmarterHQ

• Generates higher engagements

• Reduces unsubscribe rate and enhances users retention

Users feel happy and content when they get relevant emails they like and want to receive. They do not feel like you are bombarding them with unnecessary sales-y emails. Such understanding creates mutual trust and loyalty, which leads to longer user retention. As a result, users tend to unsubscribe less.

• Build stronger relationships with your customers

If you want to build brand loyalty and a stronger relationship with your subscribers, you must treat them as humans, satisfy their wants and make them feel like they matter.

Developing an email personalization strategy helps you achieve that by bridging the communication gap between you and the subscribers.

For example, Sending a weekly summary of their activity on your site or app can help them track their progress and give them a better experience within their inbox.

• Sets your brand apart from your competitors

If you are personalizing your emails, then Congrats! You are among 55% of marketers who prioritize the personalization of their email program.

But, to stand out, you need to look beyond the user's name, as every brand knows.

So, you need to ask yourself what you know about your customers that no other brand does.

For instance, Airbnb knows when and where you visited during summer vacation because you booked a hotel with them. This information is unique to Airbnb and using that; they send personalized emails to connect and communicate with their users. No other brand can know about this, which sets your brand apart from others.

How to create personalized emails?

3 steps to create personalized emails

The users' data drive personalization. So, the first step is to collect the data. After collecting the data, you must analyze it and create various segments.

Step 1: Collect user's data

Data is that pillar without which personalization can't exist. But how do you gather this data? There are many ways you can use such as:

  • Ask users about their preferences, interests, and pain points via feedback forms, surveys, polls

  • Set up a preference center to let users tell you what kind of content they prefer.

  • Use your ESP's analytics to track users' interaction with your email campaigns.

  • Track users' interactions on your website using third-party tools like Google analytics.

What kinds of data can you use for personalizing emails?

Four type of data for personalized emails: User attributes, Event data, Data feed, and Metadata

You can use the four kinds of customer data for personalizing email content:

1. User attributes

User attributes define who your customers are. It includes basic details that shape their identities, such as their

  • contact information

  • geographic location

  • preferred communication channels

  • how and when they joined your website or app

  • devices they use

Attributes give you a holistic view of your customers and serve as a great starting point for dynamic personalization and segmentation.

2. Event data

Event data is activity-based information about your customers. Events tell a story about how your users interact and engage with your brand, giving you a greater understanding of their changing interests and preferences over time.

Event data gives you a multidimensional view of your customers' behavior throughout their journey.

3. Data feeds

A data feed is a way of sending structured and up-to-date information from one source to another. It's a form of data exchange that imports external data into your messaging templates.

4. Metadata

Metadata is data about data. It's descriptive data about products and services that make your brand stand out from competitors. With metadata, you can gain customer-specific insights and create individualized experiences that deliver even more value to your audience.

This data will be the foundational pillar for making rational and intelligent decisions about which content will serve them and the action you ask them to take.

But, before making that decision, you need to do one other thing - Segmentation.

Step 2: Segment users based on data you've collected

Segmentation is the next step on the ladder, which leads to personalization. It helps you shift from - telling your whole email list, Hey! We launched a new product 🎉to tell those interested and need to hear about the launch.

This way, you can ensure that interested users get more personalized one-to-one communication valuable to them.

You can segment your email list and send more personalized and relevant email campaigns using the collected data.

Step 3: Creating the personalized emails

It's time to make personalized emails. So, what are you going to personalize?

There is no limit to how and what you can personalize. From the subject line to the CTA buttons, you can personalize many variables.

With the right data and tools, you can develop email personalization strategies to generate higher ROI and maintain long-lasting customer relationships.
