Segment Email List by User Intent
At Against Data, we're all about reducing noise, so when it came to building our email list, segmentation wasn't just a tactic—it was a responsibility. One example that worked well was when we asked new subscribers a single, lightweight question during sign-up: "Are you trying to clean up your company's email marketing, or your personal inbox?" That one choice allowed us to split our list into two core segments: B2B teams looking for compliance-friendly email strategies, and individuals who just wanted to escape newsletter overload. From there, our messaging shifted—B2B folks got content on list hygiene, opt-out flows, and retention analytics, while individual users received tips and tools to unsubscribe efficiently and reclaim their inbox. The result? Higher open rates, fewer unsubscribes, and an audience that felt like we were speaking their language—because we were.
Tailor Content to Specific Pain Points
I grew an email list to over 20,000 people in less than a year by using lead magnets that spoke directly to specific pain points. Each one was created for a different group. For example, SaaS founders dealing with churn, agency owners stuck at a revenue ceiling, and solo consultants facing inconsistent income.
I built the opt-ins with logic-based forms. That way, each person was tagged based on both what they did and why they did it. Instead of just labeling someone as a founder or consultant, I focused on deeper themes like customer retention, hiring bottlenecks, or lead quality.
Those tags shaped everything after the signup. SaaS founders received a sequence focused on retention strategies, product-led growth tips, and frameworks they could apply immediately. After three value-driven emails, they'd get a soft pitch for a call or toolkit.
Agency owners received more direct content. Shorter emails with quick wins and operational breakdowns that matched their fast-paced mindset.
Consultants saw longer-form content with storytelling because trust and identity mattered more in that segment.
The goal was to make each person feel like the emails were written just for them. The same core ideas were presented through different lenses depending on who was reading.
For automation, I used platforms like ConvertKit and Customer.io. Most of the flows triggered based on two things: the problem someone shared when signing up and how far along they were in the funnel.
So if someone mentioned churn and didn't book a call within a week, they'd shift into a nurture sequence filled with case studies showing real outcomes. If someone started booking a call but didn't complete it, they received a short reactivation series that echoed their original form responses.
Segmentation only works when the writing matches the reader. It's not about building a complicated system. It's about knowing exactly what each group needs to hear and when they need to hear it.
Use Lead Magnets for Targeted Segmentation
We were launching an educational product for entrepreneurs and noticed that there were both beginners and experienced CEOs among our subscribers. If you write the same content for everyone, no one reads it. So instead of the standard "subscribe to the newsletter" form, we launched three different lead magnets:
1. Checklist for beginners
2. Case studies for practitioners
3. Market analytics for executives
Each lead magnet automatically added a person to the relevant segment in our CRM, and then we wrote email series "in the language" of this group: some wanted simplicity, some wanted numbers, and some wanted trends.
After two months, we had a 47% increase in opens and double the clicks compared to the previous "universal" newsletter.
My advice:
Segmentation doesn't necessarily start with demographics - it starts with motivation. Ask yourself: "Why did this person subscribe?" and answer it through a lead magnet. This is your simplest filter, and it works from the very first email.
Create Custom Resources for Distinct Audiences
One successful example of building a segmented email list was during a product launch where we offered a free resource tailored to three distinct audiences: marketers, sales professionals, and startup founders. Each landing page had custom copy and a sign-up form that tagged subscribers based on their profession. This allowed us to segment the list by interest from the start.
Post-signup, we sent targeted email sequences addressing their unique challenges—marketers received content on campaign strategy, sales professionals got lead conversion tips, and founders were served growth hacks and leadership insights. This approach resulted in significantly higher engagement, with open rates exceeding 40% and click-through rates more than doubling our average.
Tailoring content to speak directly to each segment's needs builds trust and relevance, which in turn drives better conversions. The key takeaway: segmentation isn't just about personalization—it's about delivering true value to each audience group.
Categorize Subscribers Through Lead Magnets
One example of how I've successfully built an email list segmented by interests is through a lead magnet strategy. We offered a free downloadable guide that appealed to different customer segments. For instance, one version was tailored for beginners and another for more advanced users. When users signed up for the guide, they were asked to select their interests from a simple survey or form field, helping us categorize them into specific segments such as new users, advanced users, or prospective customers.
Once segmented, I tailored the email marketing campaigns to each group. For beginners, we sent onboarding tips and educational content, while for advanced users, we shared product updates, advanced strategies, and exclusive offers. This personalization increased engagement because each segment received content relevant to their specific needs. We also used tools to track behavior and adapt messaging based on how each segment interacted with our emails. Over time, this approach led to better open rates, higher click-through rates, and more conversions, as each email felt tailored and valuable to the recipient.
Match eCommerce Businesses with Relevant 3PLs
When we built our email marketing strategy at Fulfill.com, our most successful segmentation approach mirrored how we match eCommerce businesses with 3PLs in our platform.
We've segmented our email list across multiple dimensions, including order volume tiers, product niches, and specific logistics needs. For instance, we created distinct segments for high-volume DTC brands shipping lightweight apparel versus specialized food and beverage companies with temperature-controlled requirements.
This data-driven approach came from a key insight I had after speaking with dozens of frustrated eCommerce founders: generic 3PL advice simply doesn't work because fulfillment needs vary dramatically across business models.
In practice, our segmentation lets us deliver hyper-relevant content. When we notice an emerging trend in retail fulfillment, we don't blast our entire database - instead, we target specifically affected segments. For example, when new regulations affected CBD shipping last year, we only notified relevant merchants with compliance guidance and partner recommendations.
Our email tailoring follows three principles:
1. Problem specificity - addressing the exact pain points of each segment
2. Solution matching - highlighting 3PLs with proven success in their category
3. Growth stage relevance - scaling advice that matches their current operations
The results speak for themselves - our targeted campaigns achieve 3x higher engagement than our general newsletters. One D2C beauty brand told me they finally found their perfect 3PL partner after opening our email because, for once, the recommendations actually matched their specific needs.
In the 3PL world, one size never fits all - and our email marketing reflects that reality.
Segment by Industry Interest for Personalization
One example of how I built a segmented email list was during a product launch at AIScreen. We initially collected basic contact information but then asked specific questions in a survey about industry interests (e.g., retail, healthcare, education) to better understand our audience. Using this data, I created segments based on their responses, ensuring we could send more targeted content. For instance, retailers received emails focused on digital signage for promotions, while healthcare professionals received case studies on patient engagement.
To tailor my email marketing, I use dynamic content blocks within our email platform, so each segment gets a personalized message relevant to their needs. I also track engagement metrics like open rates and clicks to continuously refine the segments and improve future emails. This strategy not only boosted our engagement but also helped us convert more leads by speaking directly to each group's specific pain points.
Combine Geographic and Service-Based Segmentation
Over the years, one thing that has made our email marketing more effective is segmenting by both geography and service interest. We work with clients across multiple regions, so we built out country-based segments early on to reflect local hiring realities. A client in the UAE isn't dealing with the same tech talent pool or salary expectations as one in Germany. That alone helped us get better open and reply rates because the content actually spoke to what was happening on the ground.
We're also layering in segmentation by service line — whether someone's more focused on contract staffing, long-term placements, or niche hires like DevOps or AI roles. Our CRM lets us tag contacts by interest based on past conversations or forms they've filled out, so when we send a case study or hiring trend report, it actually lands. This kind of targeted approach has helped us move away from generic updates and build stronger relationships, especially with clients we haven't worked with yet but want to keep engaged.
