We’ve very thoroughly covered what makes great email content. But it’s just as important to nail down exactly who you are sending to. After all, step one of connecting with subscribers is showing that you understand their unique perspectives!

The practice of dividing your email subscribers into smaller, targeted groups is called email segmentation. This approach allows marketers to tailor messages to meet the unique interests, behaviors, and needs of different groups of people. Email marketing segmentation enhances the relevance and effectiveness of your campaigns through a personalized touch! And this level of email personalization shouldn’t be ignored, as personalized emails deliver 6x higher transaction rates.

Thanks to the power of data science and generative AI, marketers can craft this style of custom content more quickly than ever. Backstroke’s email subject line generator offers customers Audience Filters. They can be combined every which-way to enhance your email segmentation strategy.

Here, we’ll take a glimpse into the different groups it allows users to generate AI messages for, with links to guides covering each more thoroughly.

Let’s dig into how the Audience Filters available in Backstroke’s email subject line generator enhance your email marketing segmentation strategy.

This specificity goes way deeper than ChatGPT, hyper-targeting the exact email segmentation parameters you specify at any given time.

Email Segmentation Option 1: Location

Audience Filters allow users to select between four different U.S. regions—or any combination of them—to target in their email segmentation strategy: The East, The South, The Midwest, and the West. 

After making selections of which locales to send to, your email segment’s regional preferences will be applied to the AI messages you generate. And, boy! Does each U.S. region have its own unique preferences!

Of course, the East Coast prefers brevity. The South loves slang. West Coasters live for emojis . . . But their content preferences go sooooo much deeper! 

In fact, we’ve published deep dives into how to optimize your AI-generated subject lines across these regions. Click below to check our our AI subject line showdowns between:

Email Segmentation Option 2: Age Groups

Everyone’s aware of generational differences. And in the data, we see WILDLY different generational messaging preferences for email marketers to take advantage of! For example, just look at how four generations engage with messages that are in ALL CAPS vs. sentence case.

Simply put, subscribers across age groups all want unique content delivered to their inboxes. However, what makes content uniquely engaging across each group has a lot of variety! Each generation has their preferences in keywords, use of emojis, use of capitalization, slang, discounts, and more. By selecting the age groups your email segmentation strategy is targeting, its outputs will reflect them.

Email Segmentation Option 3: Income

Household Income filters get down to the nitty gritty, in regards to how thrifty or spendy subscribers truly are. Perhaps you’re sending to West Coast Gen Xers who are craving a good sale. Or perhaps you’re sending to Millennials with a tendency to doom spend. 

You can generate AI messages for wherever your audience segment lives on the spending spectrum. Simply make your Household Income selections in the email subject line generator and apply additional filters from there.
