The practice of dividing a broader audience into smaller groups based on shared characteristics — demographics, behavior, purchase history — so that messaging, offers, or campaigns can be tailored to each group rather than applied uniformly to everyone.
Why it matters
A single message rarely resonates equally well with an entire audience. Segmentation lets a team send a different message to a first-time visitor than to a lapsed customer, or a different offer to a high-value account than to a new lead — improving relevance and, typically, performance.
In a sentence
"We segment our email list by product usage, so power users get advanced tips and new users get onboarding content."
