Integration details
Description
InboxTrue checks whether an email address can actually receive mail before you send to it. 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. Use 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. InboxTrue only sees the addresses you ask it to check; it never sends email to them and never reads your inbox.
