The optional SMTP probe is available but defaults to off for bulk, making it faster for pure format and domain-level checks.","instructions":null,"reviewSummary":null,"reviewSummaryHighlights":null,"reviewSummaryConcerns":null,"reviewSummaryGeneratedAt":null,"activationCount":0,"lastUsedAt":null,"lastSuccessfullyRanAt":null,"lastHealthCheckAt":"2026-10-22T15:23:49.132Z","isFirstParty":false,"canonicalSlug":"machina-agent-services-bulk-email-validation-65869434"}
