Campaigns
Bulk sending, with three things a bulk sender needs and rarely has: a gate on every recipient, a cost you can see before you send, and a stop that takes effect immediately.
Every recipient is gated individually
A campaign is not an exemption from the outbound gate. Each recipient is checked for consent and capability, and the ones that fail are reported as refused rather than silently dropped or silently sent.
Cost before, not after
A campaign shows what it will draw from the balance before it runs, at the destination rates it will actually pay. A send that would exhaust the balance halfway is refused at the start rather than discovered in the middle.
Stop means stop
Pausing a running campaign stops the next send, not the next batch. Work already claimed is finished; nothing new is started.
Reporting on what arrived
The campaign report separates accepted from delivered, because they are different facts and only one of them means the message reached someone. A campaign with a healthy send count and a poor delivery ratio is exactly the signal that matters.
