Upload a CSV, review valid and invalid rows, and fire one send per valid row.
When one recipient at a time is too slow — an event list, a target-account push, a quarter-end wave — Bulk gets a whole CSV out the door in one pass. Each valid row becomes its own send, with its own tracking and its own engagement story.
After the batch fires, every send behaves like a normal single send: it appears on the Sends page with its own status, gets a tracking number when it ships, and reports engagement individually. Alerts fire per send using your workspace defaults.
Watch your stock before firing a large batch — a bulk run draws down inventory fast, and out-of-stock box types block sends. The Boxes page shows stock per type and takes reorder requests.
Every guide here lives in the in-app Help Center too — open Help in the sidebar.
