Segments do not continuously evaluate property rules.
If your application needs rule-driven membership, calculate the rule in your system and synchronize the resulting membership deliberately.
Create a segment
Open Segments, create a clear name, then add existing contacts. Use names that explain the business boundary, such as Cape Town beta customers or Security incident contacts. Avoid names tied to a one-time date unless the group is intentionally temporary.Manage membership
Open a segment to inspect its contacts. Add an existing contact or remove a current member. Removing membership does not delete the contact, its properties, or its topic preferences.Send to a segment
The Email API accepts one segment ID into.
The ID must be the only recipient and cannot be combined with CC or BCC.
Signal resolves at most 50 recipients for one audience send.
Each resolved recipient receives an independent message record and lifecycle.
Before sending:
- Confirm the membership is current.
- Confirm the communication purpose and topic preference.
- Account for global subscription and suppression state.
- Use test mode for request-path validation, then perform a controlled real send.
Delete a segment
Deleting the segment removes the grouping. It does not delete member contacts. Remove or replace application references to the segment ID before deletion.SDK example
