Segmentation in Kit comes down to three building blocks: tags, segments, and automations. You tag subscribers based on what they've bought, what they're interested in, and how engaged they are. You build segments that combine those tags into meaningful groups. And you set up automations that apply tags automatically so the system stays current without manual upkeep. The result: every broadcast you send can speak directly to the people receiving it — buyers get different emails than prospects, highly engaged subscribers get different offers than people who haven't opened in months.
What you’ll walk away with:
- A consistent tag structure covering purchases, interests, and engagement
- Automations that tag subscribers based on their actions
- Dynamic segments that update as subscribers gain or lose tags
- Targeted broadcasts that speak to each group's relationship with you
Why Kit for audience segmentation
Kit (formerly ConvertKit) was built around a subscriber-centric model rather than a list-centric one. That distinction matters for segmentation. In list-based systems like Mailchimp, the same person can exist on multiple lists with separate records, making it hard to build a unified view of who they are. In Kit, every subscriber is a single record with tags attached. You're segmenting one audience in different ways, not managing separate lists that overlap.
Kit's visual automation builder is the other piece that makes segmentation practical for course creators. You can set up rules like "when someone clicks a link about yoga teacher training, tag them as interested in yoga" — and that tag gets applied to every subscriber who takes that action, indefinitely. You build the automation once and it runs in the background.
The subscriber-centric architecture also means you're not paying for the same person twice. If someone signed up for your free guide and also purchased your course, they're one subscriber with two tags — not two entries on two lists inflating your bill.
Step-by-step: Segmenting your audience in Kit
Define your segments before you build anything
Before touching Kit's interface, write down the three to five distinctions that matter most for your course business. For most creators, these fall into three categories:
- Purchase history — Who has bought which product? A subscriber who purchased your intro course is a warm lead for your advanced course.
- Topic interest — What are they interested in? If you teach multiple topics, knowing which topic brought someone in tells you what to offer next.
- Engagement level — How active are they? Subscribers who open every email and click links are your most engaged audience. People who haven't opened in 90 days might need a re-engagement sequence.
Write these out in plain language first. "People who bought Course A but not Course B." "People interested in topic X." These become the segments you'll build in Kit.
Set up your tag structure
In Kit, go to Subscribers and then Tags. Create tags that map to the distinctions you identified. Use a consistent naming convention:
- purchased: [course name] — one tag per product
- interest: [topic] — one tag per content topic or lead magnet
- source: [origin] — how they found you (webinar, blog, referral, podcast)
- engagement: active and engagement: cold — updated by automations based on open/click behavior
Start with the tags you need right now. Five to ten tags covering your core products and two to three interest areas is a solid starting point. The naming convention matters more than the number — when you have 25 tags six months from now, you'll be glad they're organized by prefix.
Create automations to tag subscribers automatically
Manual tagging doesn't scale. The power of Kit's segmentation comes from automations that tag people based on their actions. Common automations for course creators:
- Form-based tagging — When someone subscribes through a specific form or landing page, apply a tag.
- Link-click tagging — When someone clicks a specific link in a broadcast, apply a tag. Useful for gauging interest in a topic you haven't built a product for yet.
- Purchase tagging — When a subscriber purchases through your course platform, apply a "purchased: [course name]" tag. Kit integrates natively with several platforms; for others, Zapier handles this.
- Engagement-based tagging — Use Kit's conditions to check whether a subscriber has opened or clicked any email in the last 60–90 days. If not, tag them "engagement: cold."
Each automation runs continuously once you activate it. New subscribers get tagged as they take actions, and your segments update in real time.
Build segments from your tags
Now that tags are being applied automatically, create segments that combine them into the groups you defined in Step 1. Go to Subscribers, then Segments, and create a new segment using Kit's filter builder. Segments in Kit are dynamic — they update automatically as subscribers gain or lose tags. A few examples:
- Warm prospects — Tagged "interest: [topic]" but NOT tagged "purchased: [related course]."
- Upsell candidates — Tagged "purchased: [intro course]" but NOT tagged "purchased: [advanced course]."
- Engaged non-buyers — Tagged "engagement: active" but no purchase tags.
- Cold subscribers — Tagged "engagement: cold." Candidates for a re-engagement sequence.
Personalize your broadcasts by segment
When you create a broadcast in Kit, you can choose which segment receives it. This is where the setup work pays off. Instead of sending the same announcement to everyone, you tailor the message to the audience.
Launching a new advanced course? Send one version to your "upsell candidates" segment that references their experience with the intro course. Send a different version to your "warm prospects" segment that introduces the topic from scratch. Exclude your "cold subscribers" segment entirely — they're not opening emails anyway, and sending to them hurts your deliverability.
Track segment performance
After you've been sending segmented broadcasts for a few weeks, review the numbers. Kit shows open rates and click rates per broadcast, and you can compare performance across segments.
Pay attention to your cold segment's size relative to your total list. If it's growing faster than your active segment, you have an engagement problem upstream — your content isn't resonating, or you're attracting subscribers who aren't a good fit. If your "purchased" segment is growing steadily, your funnel is working.
Course creator tips
Use link triggers in broadcasts to discover new interests
You don't need a formal survey to learn what your audience wants. Mention two or three upcoming topics in a broadcast and link each one to a relevant page. Set up automations to tag subscribers based on which link they click. After one broadcast, you have real data on which topics your audience is most interested in — no guessing, no polling, just observed behavior.
Clean your cold segment quarterly
Subscribers who haven't opened an email in 90+ days are dragging down your open rates and can hurt deliverability. Every quarter, send a re-engagement sequence to your cold segment. Anyone who doesn't respond gets unsubscribed. This feels counterintuitive (fewer subscribers!) but it improves your deliverability, open rates, and the accuracy of your engagement data.
Start with purchase-based segments first
If you're new to segmentation, the single most valuable distinction is who has bought something and who hasn't. That one tag — "purchased" vs. no purchase tag — lets you separate customer communications from prospect communications. Everything else is refinement. Get the purchase tagging working first, then layer on interest and engagement tags as your system matures.
Limitations (and when to use something else)
Limited Complex Conditional Logic
Kit's segmentation works well for tag-based filtering, but it has limits if you need deeply nested rules (like "tagged A AND (tagged B OR tagged C) AND NOT tagged D with custom field X greater than 5"). If your segmentation needs involve scoring, conditional branching based on numeric data, or CRM-style lead qualification, ActiveCampaign or Drip offer more advanced segmentation engines.
No Gradient Engagement Scoring
Kit doesn't natively score engagement on a gradient — subscribers are either tagged or not, opened or didn't. If you want a lead score that weighs different actions differently (opening = 1 point, clicking = 3 points, purchasing = 10 points), you'll need to build that with custom fields and automations, which gets complicated. For most course businesses with one to five products and a list under 20,000, Kit's tag-and-segment model is more than sufficient.
Frequently asked questions
How many tags should I create in Kit for a course business?
Start with 5–10 tags covering your core distinctions: product ownership, lead source, and engagement level. Most course creators end up with 15–30 tags over time. The key is consistency — decide on a naming convention early and stick with it. Too many tags with overlapping meanings creates confusion; too few means you can't distinguish between meaningfully different groups.
Can I segment by course purchase in Kit without Zapier?
It depends on your course platform. Kit has native integrations with several platforms that can automatically tag subscribers when they purchase. If your platform doesn't have a direct Kit integration, Zapier or Make can bridge the gap. With Ruzuku, you can connect through Zapier to tag buyers automatically, so your segments stay current without manual work.
What's the difference between tags and segments in Kit?
Tags are labels you attach to individual subscribers — either manually or through automations. They're static: once applied, a tag stays until you remove it. Segments are dynamic filters that group subscribers based on tag combinations, signup dates, email activity, or custom fields. A segment updates automatically as subscribers meet or stop meeting the criteria. Think of tags as the raw data and segments as the views you build from that data.

From segments to sales
Segmenting your audience is what turns email from a broadcasting channel into a relationship channel. When you know who's bought what, who's interested in which topic, and who's actively engaged, every email you send can be relevant rather than generic. The setup takes an afternoon; the payoff compounds with every broadcast. Ruzuku gives you a place to host the courses your segments are ready to buy — unlimited courses, zero transaction fees, and a platform built around the learning experience your students deserve.
