An exclusion segment is a group you deliberately want to leave out of a campaign or message. It is the most reliable way to manage contact frequency, avoid double-rewarding and protect a control group.
*The Use for setting decides whether a segment can target, exclude, or both.*
MARK IT AS ONE
When you save a segment, the Use for setting decides where it is offered:
• Targeting & exclusions — available as both.
• Targeting only — can never be used to suppress.
• Exclusion only — can never be used to target.
Set staff numbers, known bad actors and prior winners to Exclusion only. It removes the possibility of someone accidentally aiming a campaign at the list you built to protect.
COMMON USES
• Frequency capping — exclude anyone messaged in the last 7 days.
• No double-dip — exclude consumers who already received a given reward.
• Control groups — exclude a holdout so you can measure true campaign lift.
HOW IT APPLIES
Attach an exclusion segment to a campaign or broadcast and its members are suppressed even if they otherwise match the target. Exclusions always take precedence — when a consumer is in both, they are left out.
YOU DO NOT NEED ONE FOR OPT-OUTS
Consent is enforced by the platform, not by you. Any message sends only to consented consumers, and everyone who has not opted in is filtered out server-side. That is why the count confirmed after a send is usually smaller than the segment size.
