Where Used: Never Delete What Your Customers Are Touching
Where Used is now live across your Marketing Lists, Subscription Lists, Emails, Global Segments, Contact and Account Custom Fields, Action Sets, and Brand Kits — and deletion is now blocked while any of them are still being used.
This is one of those features you don't think about until you've deleted the wrong thing.
Every marketer has a story. The "unused" Custom Field that turned out to be in three running Workflows. The Action Set somebody cleaned up that was wired to the company's biggest landing page. The Marketing List "no one was using anymore" that fed last quarter's nurture.
Where Used puts an end to that whole class of mistake.
What "Where Used" Actually Shows
Every grid for the supported asset types has a Where Used icon on each row. Click it, and a dialog opens with the full picture — organized by category, one accordion per type of usage, each showing the specific items that reference the asset and linking directly to them.
For a Custom Field, that breakdown is almost embarrassingly thorough:
- The specific Workflows and split-node conditions that read the field
- Action nodes with Set Field Value Actions targeting it
- Forms (including global Actions and Conditional Actions on the form)
- Action Sets, alerts, reports, legacy Campaigns, scoring rulesets, and CRM mappings
- Token usage — every Email, Landing Page, CTA, or Form merging the field into content
- Persona-based and Liquid script references
The same model applies to the other asset types. The dialog answers the only question that matters: what breaks if I delete this?
Deletion Protection That Means Something
If an asset has any active references, the Delete Action in the grid is disabled — with a tooltip explaining why. Open the Where Used dialog and you see exactly what to address first.
API-level deletion attempts are rejected the same way, with a clear error listing the number of active references. You can't sneak around the guardrail from a script.
❌ Don't delete first and find out later.
✅ Do open Where Used before any cleanup pass — and treat the dialog as the to-do list.

Why This Matters
Marketing operations is mostly the art of not breaking things in production. Where Used is one of the most useful "don't break things" tools we've ever shipped — not because it's flashy, but because the cost of the alternative is enormous and usually invisible until it isn't.
Get Started
- Pop open any supported DataGrid — Marketing Lists, Custom Fields, Action Sets, whatever you're cleaning up
- Click the Where Used icon on any row before you touch the Delete column
- Work through the categorized usages first — then come back and delete safely
A small feature with outsized impact. You'll feel it the first time it stops you.
