# Alias of POST /campaigns/{campaignId}/launch

`POST /campaigns/{campaignId}/send`

Alias of `POST /campaigns/{campaignId}/launch` — activates the
campaign and runs the launch pipeline. (Before the campaigns
refactor this was a batch "mark sequences ready" op; it is now the
campaign-activate launch.) Same body, params, and result shape.
