It inspects the address's domain and talks to its mail server, then reports a clear verdict: valid, maybe valid, invalid, ambiguous, or a temporary or permanent error, with a retry hint when a server asks us to try again later.\n\nUse it to clean up a contact list you pasted into the chat, double-check a lead before outreach, or confirm a signup address looks real. You can also ask how many InboxTrue credits remain on your account.\n\nInboxTrue only sees the addresses you ask it to check; it never sends email to them and never reads your inbox.",
