Publishing & calendar
Hootsuite
The publishing pages show bulk scheduling of up to 350 posts at once, a calendar covering paid and organic across networks in list and calendar views, best-time heat maps with automatic scheduling, and documented per-network constraints such as Bluesky's 300-character captions. Publishing failures are visible to me mainly as after-the-fact fix notices; we found no public information on failure notifications with one-click retry, link shortening with UTM rules, or previews matching each network's actual rendering.

A calendar with day, week and month views, queue-based scheduling, patented ViralPost best-time publishing, multi-format publishing to Threads and Instagram, and asset imports from Canva, Bynder and Google Drive are all documented. We found no public information on drafts, drag-and-drop editing, per-network content variants, bulk or CSV import, previews matching each network's rendering, or any failure notification with retry — and what happens when a post fails overnight is the part I need in writing.
