🚀 Sendbox is live — this documentation is a work in progress.

Tags

Tags apply to both leads and mailboxes.

  • On leads — organize your contact database, and drive automatic tagging: give a tag a plain-language description and the AI reply classifier can apply it to matching replies automatically.
  • On mailboxes — organize your sending fleet, and use tag-based selection when configuring a campaign’s mailbox pool.

A tag’s sentiment (Positive/Negative/Neutral) is metadata only — it doesn’t change behavior on its own, but is available to anything reading tag data (including via the API/MCP).

Deleting a tag removes it from everything it’s attached to — this can’t be undone. Only an owner or admin can delete a tag.
