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.
FAQ
- What signals does the full validator return?
- Syntax, normalized form, subaddressing, role address, public domain, relay domain and provider, disposable status, and detection source.
- How is this different from mailbox verification?
- EmailGuard classifies address characteristics. It does not SMTP-ping inboxes or guarantee deliverability.
- Can I use this at production volume?
- The browser tool is rate-limited. For volume, webhooks, and team access, use the EmailGuard API with an API key.
