Email Segmentation: What Each Platform Lets You Do at Each Tier
Every email platform claims to offer segmentation. The reality is that basic tag-based segments are free everywhere, behavioral segments cost $15–$49/mo, and predictive segmentation is a premium feature costing $79/mo or more. This guide breaks down exactly what segmentation features you get at each price tier across Mailchimp, Kit, beehiiv, ActiveCampaign, and Brevo.
Three Levels of Segmentation
1. Basic Segments (Available on Free Tiers)
Filter contacts by tag, custom field, location, or signup source. Every platform in this comparison offers basic segmentation on their free or lowest tier. This handles 80% of segmentation needs for lists under 10,000.
2. Behavioral Segments ($15–$49/mo)
Filter by email engagement (opens, clicks), website activity (pages visited, products viewed), purchase history, and automation interactions. This is where segmentation becomes genuinely powerful for revenue growth.
3. Predictive Segments ($79/mo+)
AI-driven segments that predict purchase likelihood, churn risk, or optimal send time. Only ActiveCampaign Pro ($79/mo) and Mailchimp Premium ($350/mo) offer true predictive segmentation. Most businesses under 25,000 contacts don't need this.
Segmentation Features by Platform and Tier
| Feature | Mailchimp | Kit | beehiiv | ActiveCampaign | Brevo |

ActiveCampaign: The Segmentation Leader
ActiveCampaign has the deepest segmentation capabilities in this comparison. Even the Starter plan ($15/mo for 1,000 contacts) includes tags, custom fields, and engagement-based segments. Plus ($49/mo) adds site tracking, lead scoring, and CRM-integrated segments. Pro ($79/mo) unlocks predictive sending and split automations based on predicted behavior.
The gap between ActiveCampaign and everything else becomes significant at the behavioral level. Site tracking on Plus ($49/mo) lets you segment by pages visited, products viewed, and custom events — capabilities that Mailchimp charges $20/mo for (Standard) and Kit and beehiiv don't offer at all.
Mailchimp: Broad but Expensive at Scale
Mailchimp offers strong segmentation that improves with each tier. Free ($0, 250 contacts) gives you basic tag and field segments with a 5-condition limit. Essentials ($13/mo) adds engagement-based filtering. Standard ($20/mo) adds predicted demographics, purchase likelihood, and customer lifetime value segments.
The issue: Mailchimp's contact-based pricing makes advanced segmentation expensive at scale. Standard is $20/mo at 500 contacts but jumps significantly as your list grows. Full predictive segmentation requires Premium ($350/mo).
Kit: Simple Tags That Work
Kit's segmentation model is built entirely around tags and custom fields. The Newsletter plan ($0, 10,000 subscribers) includes basic tagging and segments. Creator ($39/mo) adds engagement-based filtering. Creator Pro ($79/mo) adds subscriber scoring.
Kit doesn't offer site tracking or behavioral segmentation. Its approach is simpler: tag subscribers based on what they click, what they buy, and what forms they use. For most creator businesses, this is sufficient.
beehiiv and Brevo: Good Basics
beehiivoffers audience segmentation on Launch ($0) with basic filters. Scale ($49/mo) adds engagement-based segments and advanced analytics. No lead scoring or site tracking — beehiiv is a newsletter platform, not a marketing automation tool.
Brevo provides surprisingly robust segmentation even on Free ($0). Contact attributes, engagement filters, and transactional behavior are available early. Standard ($18/mo) adds site tracking and marketing automation. The combination of unlimited contacts and decent segmentation makes Brevo a strong value play.
The Opinionated Verdict
If segmentation is your priority:ActiveCampaign. The depth of behavioral and predictive segmentation is unmatched. Plus at $49/mo gives you lead scoring and site tracking that competitors charge $350/mo for (Mailchimp Premium) or don't offer at all.
If you just need tags and basic segments: Kit (free for 10K subscribers) or Brevo (free for unlimited contacts). Both provide tags and basic segment builders on free tiers.
If you need behavioral segments on a budget:Brevo Standard at $18/mo includes site tracking and automation-triggered segments. That's less than half the price of ActiveCampaign Plus ($49/mo) for similar behavioral capabilities.
Frequently Asked Questions
Do I need behavioral segmentation?
If you sell products or services online and your list is over 5,000, behavioral segmentation (based on site visits, purchases, and engagement patterns) typically improves revenue per email by 20–40%. Below 5,000, basic tag-based segments work fine.
What is predictive segmentation?
AI-driven grouping that predicts subscriber behavior (purchase likelihood, churn risk, optimal send time). ActiveCampaign Pro ($79/mo) and Mailchimp Premium ($350/mo) offer it. Most businesses under 25,000 contacts see better ROI from behavioral segments first.
Which platform has the best free-tier segmentation?
Brevo Free allows unlimited contacts with basic segmentation. Kit Newsletter Free offers tags and basic segments for up to 10,000 subscribers. Mailchimp Free limits you to 250 contacts with a 5-condition segment limit.
Is lead scoring worth paying for?
Lead scoring is valuable if you have a sales team following up on email leads. ActiveCampaign Plus ($49/mo) and Kit Creator Pro ($79/mo) offer it. If you're a solo creator or small newsletter, basic engagement segments serve the same purpose for free.
