Overview
Smartlead runs cold email campaigns across unlimited mailboxes, rotating sending infrastructure automatically to protect deliverability. Where most email tools treat the inbox as a destination, Smartlead treats it as an engineering problem — warming accounts, rotating domains, and scoring reply intent without manual intervention. API and MCP server support lets AI agents query campaign health, pause sequences, and update lead status in real time.
