Catch-all recovery semantics

Catch-all recovery confidence

Recovery confidence is a routing signal for catch-all results, not a guarantee that a mailbox exists.

Canonical status

risky

Status language is backed by the shared validation result contract and product publish gates.

Quality signals

  • recovery confidence
  • recommended action
  • catch-all

Recommended actions

  • Use confidence to segment review queues
  • Keep confidence separate from canonical status
  • Avoid deterministic mailbox-existence claims

What confidence does

Recovery confidence helps decide whether a catch-all result should be sent with caution, manually reviewed, or suppressed according to your list policy.

What confidence does not do

It does not turn a risky catch-all into valid, send verification emails, or claim deterministic mailbox existence.

Common questions

Can confidence change the validation status?

No. Recovery fields are separate from the canonical validation status and should be interpreted as routing guidance.
