It is especially useful for agents that need to gate workflows on email format correctness (e.g., before storing user data or sending a message) and want a simple API call rather than bundling a regex or validation library. Note: this validates syntax only, not mailbox existence — for deliverability checks, a different endpoint would be needed.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-09-15T12:49:36.818Z","isFirstParty":false}
