See Why, Not Just What
Most verification tools return a score and nothing else. RocketVerifier shows the full evidence trail behind every verdict - so you can trust it, debug it, and explain it.
Example evidence trail
7 Evidence Signals, Every Time
Syntax check
RFC-compliant format validation - catches typos and malformed addresses before any network call.
DNS / MX resolution
Confirms the domain exists and has valid, reachable mail server records.
SMTP handshake
Connects to the actual mail server (without sending mail) to check whether the mailbox is accepted or rejected.
Disposable / role detection
Flags temporary-email providers and generic addresses like info@ or support@.
Catch-all confidence
For accept-all domains, scores naming-pattern and reputation signals to resolve a send-safe verdict.
Final score computation
Combines every signal above into a single 0-100 confidence score, with the reasoning preserved.
Common Questions
What does "explainable verification" mean?
Every RocketVerifier check returns not just a verdict (deliverable/undeliverable/risky) but the full evidence trail behind it - which signals passed, which failed, and why - instead of a single opaque score.
Why does the evidence trail matter?
When a client, compliance team, or your own QA process asks "why did this email fail?", a bare score gives you nothing to point to. The evidence trail lets you show the exact signal (bad MX record, SMTP mailbox-not-found response, disposable domain match, etc.) that drove the verdict.
Is this available via the API, or only the dashboard?
Both. The `/v1/verify` API response includes an `evidence` object with per-check status and detail alongside the standard verdict fields, so you can build the same transparency into your own product or pipeline.
Does showing evidence slow down verification?
No - the evidence trail is a byproduct of checks that already run as part of every verification (syntax, DNS/MX, SMTP, catch-all scoring); we simply expose the intermediate results instead of discarding them.
