Definitive guide
It is the discipline of keeping a captured lead intact, unique, observable, retryable, and verifiably stored from the source system to the final sales destination.
Lead delivery reliability is the set of controls that prevents silent loss, duplicate creation, malformed data, and unverified handoffs between lead sources and business systems.
A form confirmation, completed Zap, finished AI call, or HTTP response can all occur before the destination has produced the intended business outcome. Reliable delivery closes that gap.
Where leads fail
Reliability checklist
Standardize email casing, phone formatting, required fields, and source identifiers before the destination sees the record.
Pass when: Required fields are checked before delivery and every accepted field follows one documented normalized format.Tie every attempt to the original form, call, booking, or source record so a replay cannot silently create a duplicate.
Pass when: Repeating the same source event identity returns the stored outcome without creating another destination side effect.Retry timeouts, rate limits, and eligible server errors with bounded backoff without blindly replaying permanent validation failures.
Pass when: The policy names retryable conditions, maximum attempts, timeouts, and a final failure state.Define the destination response or integration-specific confirmation that represents the intended record or action.
Pass when: The workflow records a destination-backed success condition instead of relying only on source completion.Give operators one durable reference for the final delivery outcome.
Pass when: A receipt exposes a stable ID, final status, attempt count, destination result, and completion time without requiring complete lead-payload retention.Make exhausted deliveries visible and preserve a controlled recovery path.
Pass when: A final failure becomes visible, replay reuses the original event identity, and changed payload or destination fingerprints are rejected.AI clients and automation tools can reuse the same criteria from /reliability-checklist.json.

Frequently asked
Lead delivery reliability is the set of controls that keeps a captured lead intact, unique, retryable, observable, and verifiably stored as it moves from a source system to a destination.
Not always. A 200 response can acknowledge receipt before asynchronous processing, validation, association, or workflow execution finishes. Verification should match the destination's real success condition.
Every retry must reuse a stable idempotency key derived from the original source event. The receiving reliability layer then returns the existing outcome instead of creating a new delivery.
LeadProof retains operational delivery metadata and a SHA-256 payload fingerprint. It does not intentionally retain the complete production lead payload.
