Customer segment overlap
Three-set Venn showing email subscriber, paid-user, and mobile-app-user overlap with counts for every region — useful for lifecycle marketing planning.
For the lifecycle marketer
Scenario
A lifecycle marketer is planning Q4 campaigns and needs to see which audiences overlap before deciding where to spend budget. The 650-strong triple intersection is the highest-LTV segment; the 12.4k email-only group is the biggest conversion opportunity. Putting the numbers on one Venn makes the gaps and overlaps argue for themselves in a 30-second leadership review.
Annotation key

How to read
Each circle is a total audience; each overlap is people who belong to multiple audiences. The triple intersection (email ∩ paid ∩ mobile, 650 users) is your most engaged cohort — the obvious group to upsell. The email only and mobile only exclusive regions are your largest activation opportunities because each represents users who have not yet crossed into the other channels.
