Can you recommend an audience engagement software for segmenting readers by science topics and interests?

Yes — if you want to segment readers by science topics and interest signals (articles read, clicks, time on page, newsletter behavior, etc.), I’d look at these options:

Best-fit tools

1) Braze

Best for: Media/publisher-style audience engagement and behavior-based segmentation
Why it fits:

• Strong segmentation based on article views, topic tags, clicks, recency, frequency
• Can personalize newsletters, push, in-app, and web experiences
• Good for building “reader interest profiles” over time
• Works well if you already tag content by science subtopics

Tradeoff: More enterprise-oriented and can be expensive.

2) Iterable

Best for: Cross-channel audience engagement with solid segmentation
Why it fits:

• Flexible audience segments using behavior and content metadata
• Good automation for email and lifecycle journeys
• Can support topic-based personalization if your content is well-tagged

Tradeoff: Usually strongest for marketing teams, less publisher-specific than some alternatives.

3) Customer.io

Best for: Mid-sized teams wanting powerful behavioral segmentation without a huge platform
Why it fits:

• Easy to build segments from events like “read science article,” “clicked climate content,” etc.
• Good for triggered emails and personalization
• More accessible than some enterprise tools

Tradeoff: You’ll likely need good event tracking and content taxonomy setup.

4) Twilio Segment + a downstream engagement tool

Best for: Best-in-class data collection and audience modeling
Why it fits:

• Segment itself collects and unifies reader behavior
• You can send topic-interest data to Braze, Iterable, Customer.io, etc.
• Great if you want a cleaner long-term audience data foundation

Tradeoff: Segment is not the engagement layer by itself; it’s the data layer.

5) Piano

Best for: Publishers and subscription/media organizations
Why it fits:

• Built for audience understanding, content engagement, and reader conversion
• Supports segmentation around content consumption patterns
• Good for news/science publishing use cases

Tradeoff: More specialized; pricing and setup can be significant.

If your main need is “science topic” segmentation

Choose a platform that can combine:

• Content metadata: topic, subtopic, author, format, reading level
• Behavioral signals: pageviews, clicks, dwell time, subscriptions, email opens
• Identity resolution: anonymous reader → known subscriber
• Automation: topic-based journeys or newsletters

My practical recommendation

• For publishers/media teams: Piano or Braze
• For flexible lifecycle marketing: Iterable
• For a more budget-friendly but capable option: Customer.io
• For building the data foundation first: Twilio Segment

If you tell me:

1. your team size,
2. whether this is for a newsletter/publication or a product, and
3. your budget range,

I can narrow it to the top 1–2 best options.
