Segmentation is only as useful as the information behind it. Before comparing campaign tools, decide which fields your team will maintain and what each one means.
Keep source and stage distinct
Source explains how a contact arrived. Stage describes where the relationship stands now. Agree on a short set of definitions and review records when a prospect moves into onboarding.
Check for duplicate records
Discuss how your team will identify and resolve duplicates, especially when a contact arrives through more than one channel. Check that useful notes and preferences are not lost in the process.
Record permission with context
Consider what evidence and dates your team needs for communication preferences, including withdrawals. Evaluate how those details can be reviewed before an audience is selected.
Name an owner
Decide who reviews uncertain records and who updates status after a handoff. A field without a clear owner can quickly become unreliable campaign criteria.
