Create a campaign that sends one template to every contact of one list. The campaign's channel is the template's channel; the list must not be a blacklist-type list, which is a suppression set rather than an audience.
The campaign starts in draft: nothing is sent until it is launched, and until then it can be renamed, scheduled, or deleted. Template and contact list are fixed at creation — only name can be changed afterwards.
