Clean turns raw email data into explainable trust decisions. See the evidence, preserve the receipt, clean entire lists, and put the same decision engine behind your product with one API.
Public checks use live syntax, DNS/MX and risk evidence. Authenticated policy can add bounded mailbox-level SMTP evidence without sending email.
Clean separates observation from interpretation. Signals are gathered first, uncertainty is retained, policy is applied deliberately, and the resulting decision can be reconstructed later.
Temporary provider failures and incomplete evidence are not silently converted into “invalid.” Clean can return unresolved when certainty is not justified.
Accepted results preserve observed evidence, policy output, timestamps and an immutable receipt hash for later inspection.
The same status vocabulary and decision authority follows the address from an operator’s screen into Bulk Clean and through the API.
Explore the platform →cln_7c8f…a91eSEALEDVerification is only useful if the surrounding workflow survives. Clean keeps source data intact, runs long work durably, and exposes the decision boundary to developers without creating a second truth system.
Read syntax, routing, role risk, provider characteristics, typo guidance, confidence and recommended action in one decisive view.
CSV ingestion preserves source columns while persisted rows, checkpoints, cancellation and reconciliation keep long jobs trustworthy.
Organization-scoped credentials and a versioned JSON contract put the same Clean decision engine behind forms and product workflows.

Evidence, uncertainty, provenance and immutable receipt hashes give operators and systems a durable answer to “why did Clean decide that?”

No monthly volume commitmentClean replaces vague confidence language with concrete product boundaries: one engine, four decision states, immutable receipts and published pricing.
Use Clean’s real non-SMTP preview path before you sign in, then follow the decision vocabulary into Single Verify, Bulk Clean and API.
Clean gives buyers a direct path from product capability to method, security, commercial terms and migration planning — without requiring a sales call to discover the basics.
CoreID authority, tenant boundaries, server-side credential handling, immutable evidence and bounded mailbox checks.
