Segments in iCampaign are not static lists. Instead, they are built using specific conditions or criteria that subscribers must meet. When you send a campaign, iCampaign evaluates each subscriber against the segment conditions at the time of send.

This means the segment will always include the most up-to-date list of contacts who meet your defined criteria.

⚠️ Warning: Always double-check that unwanted contacts (like internal IT contacts or test emails) are properly deleted from your subscriber list, not just removed from the segment view.
