PunchOp × Multi-ESP mail flow observability
A sourced comparison of Multi-ESP mail flow observability's documented role and PunchOp's guided-investigation hypothesis.
What PunchOp aims to add
An incident-first investigation: identify the sending system, assemble available evidence, expose missing data and recommend the next useful check.

The scopes are not equivalent. This product may provide a source, sending capability, signal or control used during the investigation.
Documented scope limit
Primarily high-volume outbound paths; limited when mail never touched that platform or Workspace admin evidence is required.
PunchOp hypothesis proximity
Strong on transport the platform sees; PunchOp would still need native Google evidence when the incident is Workspace relay or ELS.
