Zendesk sells AI or agent tooling, so it has a reason to publish flattering numbers about AI. The passage stays in the archive; read it with that in mind.
How this was checked
Checked against the source by a first reader, then confirmed independently by a second reader who fetched the source without seeing the first reader's notes (Independent review agent (Claude Sonnet 5.5), blind second pass from passage text and citation only, no repository access, 2026-10-30).
Live Zendesk help article, in the list of when a conversation ends. The text is 'Messaging : By default, the conversation ends 2 hours after the first message in the conversation, though this can be increased up to 72 hours.' The space before the colon comes from the bold label's tag stripping, which is whitespace normalization, not a dispute.
