Description
The cold email API for AI agents. Connect and warm up sending mailboxes, build sequences, add leads, launch campaigns, and read and answer replies. Send tools pass through a credential-bound policy that returns executed, awaiting_approval, or blocked, and approval never overrides suppression, opt-out, or mailbox health checks.
