Validate an email with every detection signal
Why this signal matters
One request can answer the questions product and growth teams ask at signup: Is the address well-formed? Is it throwaway? Is it a shared inbox? Is it a privacy relay? The full validator mirrors the production API response so you can evaluate fit before integrating.
