Why duplicate circulars are difficult
The same cargo or vessel can arrive through repeated sends, forwarded threads, multiple mailbox folders or different brokers. Exact message matching is not enough because formatting and wording change. A useful workflow separates email-level duplication from offer-level similarity and avoids deleting source context automatically.
Review workflow
Detect :: Compare message identifiers and normalized content before extraction. Compare :: Review offer type, ports or zones, laycan, quantity or DWT, vessel and broker details. Flag :: Mark highly similar offers as possible duplicates instead of silently discarding them. Verify :: Open the source email and confirm whether the commercial opportunity is genuinely the same. Resolve :: Keep the reviewed record and preserve the source relationship needed by the desk.
How LaycanMatch supports the process
LaycanMatch extracts cargo and vessel offers, uses duplicate checks during processing and keeps the source email available from the offer record. Possible duplicates remain visible for review. The system does not guarantee legal commission lineage or decide commercial ownership between brokers.
Fields worth comparing
For cargo offers, compare commodity, quantity, load and discharge locations, laycan and charterer or broker context. For vessel offers, compare vessel name where present, DWT, vessel type, open position, open dates and direction. Small differences may be material, so similarity is a review signal rather than proof.
