Publishing & calendar
Hootsuite
Bulk scheduling up to 350 posts at once, a calendar covering paid and organic in list or calendar views, and best-time heat maps with automatic scheduling make this a genuine working surface. But the part I live for — what happens when a post fails overnight — only shows up in a dated fix note about Facebook scheduled posts failing with error messages; we found no public information on failure notifications with a retry, drag-and-drop in the calendar, or CSV import.
Sprout Social
The calendar with day, week and month views, ViralPost® and Sprout Queue best-time scheduling, and scheduling across networks including Threads (text, image, carousel, video) are all confirmed. I found no public information on bulk upload, per-network previews, first-comment variants, or what happens when a post fails overnight — and that last silence is exactly what I would be paid to catch.
