moosend_create_draft_campaign

WRITE: create a regular (non-A/B) DRAFT campaign. It is NOT sent — sending stays a human action in Moosend.

Per-recipient activity for a campaign by type: Sent, Opened, LinkClicked, Unsubscribed, Bounced, Complained, or Activity (all). Paged (default 50, max 1000) and filterable by date.
