Additions and changes to the Twilio platform
Previously, segment samples did not refresh after initial segment creation (or after editing the conditions of a segment). With this release, segment samples are now refreshed hourly as long as Marketing Campaigns detects any changes as contacts enter or exit the segment. If no changes are detected, the next refresh will occur at 2 hours, and then 4, with a maximum delay to segment sample refresh of 24 hours.
For a real-time view of all contacts within your segment at any time, you can always export a CSV. This is not dependent on the sample refresh cadence.
For more information about the segment refresh cadence, see our segmentation documentation.
