Email marketing has been a staple of digital marketing for years. With the rise of artificial intelligence, it has become even more powerful. AI email marketing for Ecommerce and DTC brands can help boost email marketing ROI in several ways such as personalizing email content, optimizing email sending times, identifying high-performing subject lines, and more.

Let's deep dive into how AI in email marketing helps Ecommerce businesses perfect their email marketing strategies. With more successful email campaigns, your advertising cost would reduce, resulting in increased revenues.

1) Personalized content

Personalizing email content is an integral part of AI email marketing and can help boost email marketing ROI by making the recipient feel more valued. As per Salesforce, 52% of consumers were more likely to open an email if it was personalized to their interests and preferences.

A best practice of using AI-based email marketing for personalizing content is to segment your email list based on customer behavior, demographics, or other relevant information.

The most common example of AI in email marketing is Amazon leveraging AI to collect customer data such as purchase history, browsing behavior, and search history tocreate personalized product recommendations for each customer. These recommendations are then included in the customer's regular email updates, as well as on their account page.


By using personalized product recommendations, Amazon is able to increase the relevance and effectiveness of its email marketing efforts, leading to higher engagement and conversion rates.

2) Predictive lead scoring

Predictive lead scoring is about leveraging machine learning algorithms to analyze customer data and predict which leads are most likely to convert into customers. This can help boost email marketing ROI by allowing businesses to focus their efforts on the most promising leads and tailor their email campaigns accordingly. As per Marketingsherpa, organizations that leverage lead scoring mechanisms get a lift of 77% in ROI over organizations that do not use predictive lead scoring.

Best practices for using predictive lead scoring in AI email marketing:

  • Use a variety of customer data to train your predictive model, including demographic information, web browsing behavior, and engagement with past email campaigns.
  • Use the lead scoring software to segment your email list and send targeted, personalized messages to different groups of leads.

DTC brand Bombas showcases a great example of predictive lead scoring. They start by collecting data from various sources such as customer demographics, browsing behavior, purchase history, and engagement with marketing campaigns. This data is then fed into machine learning algorithms that analyze the information and predict which leads are most likely to convert into paying customers.


Based on this analysis, Bombas can then prioritize and target its marketing efforts to the leads that are most likely to convert. If the predictive model indicates that a certain group of leads is more likely to convert, the company can choose to allocate more resources toward targeting that group with personalized AI email marketing campaigns. This allows Bombas to be more efficient and effective with its sales process and help the company to increase its conversion rate.

3) Automated segmentation

Automated segmentation comprises machine learning algorithms to analyze customer data and automatically segment your email list into different groups based on specific criteria such as demographics, purchase history, browsing behavior, and more. It can help increase the relevance and effectiveness of email campaigns, leading to higher engagement and conversion rates. A study shows that targeted email campaigns have a 34.7% higher open rate and generate 26.5% more orders than no-targeted and generic ones.

Best practices:

  • Use behavior segmentation to send targeted, personalized messages to different groups of customers.
  • Monitor and analyze the results of your email campaigns to identify which types of segments respond best to different types of messages.

Online men's grooming brand Dollar Shave Club leverages data from its customer's purchase history and browsing behavior to segment its customer base.

One instance of how Dollar Shave Club uses automated segmentation is by dividing its customers into different groups based on their purchase history. For instance, customers who frequently purchase razor blades may be placed in one segment, while customers who frequently purchase skincare products may be placed in another segment.

Once these segments are created, Dollar Shave Club can then use this information to personalize its marketing efforts. For example, the company can send targeted promotions and discounts to customers in the razor blade subscribers segment for products related to razor blades. Or send skincare tips and tutorials to the skincare enthusiasts segment.

Ecommerce businesses are using AI in optimizing subject lines to improve the open rates and click-through rates of their email campaigns.

Here are a few best practices for crafting optimized subject lines:

  • Keep it short and sweet: Subject lines that are between 6 and 10 words tend to have the highest open rates.
  • Utilize natural language processing (NLP) to analyze the sentiment and tone of subject lines. This can help ensure that the subject line is appropriate for the target audience and the message of the email.
  • Use an AI email writer like Jasper or AI email generator for experimenting with subject line optimization.

Online eyewear brand Warby Parker is recognized for their intriguing and innovative subject lines. They utilize different types of customer data to personalize the subject lines of their emails.

For example, if a customer has shown interest in a specific product, using AI email automation, the customer receives an offer (in this case a free home trial) for the product.

This not only makes the emails more relevant to the individual customer, but also increases the likelihood that they will open and engage with the email.

6) Send-time optimization

Send-time optimization determines the best time to send an email to a specific recipient, based on their engagement history and behavior, aiming for higher engagement and conversion rates.

Using AI in email marketing, you can find the best time that gives your emails the highest open rate.

Here are a few best practices for using send-time optimization in email marketing:

  • Collect and analyze engagement data for each recipient, including open and click-through rates, to identify patterns in engagement behavior.
  • Monitor and analyze the results of your email campaigns to identify which types of recipients respond best to different send times.

Expedia uses data and analytics to determine the best time to send an email to each recipient, based on their engagement history and behavior. For example, they might send an email with a special offer to a customer who frequently travels on Fridays at 3 PM when they have a higher chance of being available and browsing for travel options.
