InboxTrue
Claude connectorCommunityCheck whether email addresses can receive mail before you send to them.
InboxTrue checks whether an email address can actually receive mail. It inspects the address's domain and performs proprietary checks, then reports a clear verdict: valid, maybe valid, invalid, ambiguous, or a temporary or permanent error, with a retry hint when a server asks to be retried later.
Ask Claude to validate a lead before outreach, clean up a list of contacts you pasted into the conversation, or confirm a signup address is real. Claude can also tell you how many InboxTrue credits remain on your account.
InboxTrue only receives the addresses you ask it to check. It never sends email to them and never reads your inbox. Sign in with your InboxTrue account; you can disconnect Claude at any time from Connected apps on the InboxTrue API keys page.
