Segmenting on Custom Fields

The segment condition builder has a dedicated Custom Fields tab, so you can target members by the data you've extended their profile with.

Condition types

Condition	What it does
Contains value	Matches values stored in an array field (Multi select or a Subgroup field), with Contains any of / Contains all of.
Range	A numeric field between two values. The lower bound is inclusive and the upper bound is exclusive — [from, to).
Threshold	A numeric comparison (greater than, greater or equal, less than, less or equal, equal to) against a single value.
Compare fields	Compares two numeric fields against a threshold. All four operators are shown — subtract, add, multiply, divide — but only Subtract is enabled initially; the rest are greyed out.

Picking a field

The field picker lists group fields and subgroup fields in a single dropdown. Groups and subgroups appear as non-clickable headers — only simple fields can be selected. Once picked, the selected state shows the full path (group / subgroup / field name), since the same field name can exist in more than one group.
