Schedule posts, build a queue and set up approvals

Everything to do with publishing lives on Engage → Social → Calendar.

1. Write the post

Click New post (or double-click a day in the calendar to start there). Pick the accounts to publish to, write your copy once, and add images from your Content Library or by uploading. The order you add images is the order they appear in a carousel, so it is worth getting right.

As you type, Solstral checks the post against each platform's actual rules and shows you any problems: copy over the character limit, too many images, or a format the platform does not support. Instagram cannot post text on its own, so a post without an image will be flagged before you can schedule it rather than failing later.

2. Tailor it per platform

With more than one account selected, open Tweak the copy per platform to give any of them its own version — a short punchy line for X, a longer one for Facebook. Leave a platform empty and it uses the main copy. The preview panel on the right switches between platforms so you can see each one before it goes out.

3. Choose when

You have four options. Save draft keeps it without scheduling. Schedule publishes at the date and time you pick. Publish now sends it at the next engine tick, usually within a minute. Add to queue drops it into the next free slot in a posting queue.

4. Build a posting queue

A queue is a weekly pattern of times — say Monday, Wednesday and Friday at 9am. Create one on the Queues & approvals tab, choosing the timezone and the slots. After that, "Add to queue" finds the next slot nothing else is using, so keeping a cadence stops being a daily decision. Free slots are ghosted into the calendar, so gaps in your rhythm are visible at a glance.

Queues can be edited and deleted at any time from the same tab. Changing the slots does not move posts that are already scheduled from the queue — those times are commitments someone may already have approved — so the new pattern applies from the next post you add. Deleting a queue never deletes its posts either: they keep their times and go out as planned, they simply stop belonging to a cadence.

4b. Month view and week view

The calendar has two views. Month answers “is the next fortnight covered?” and shows every post as a chip with its image, the channels it goes to and the time. Week answers “does this actually look right?” — seven columns of full-size cards with a large preview of the image or video. Drag a post to another day in either view and it keeps its time of day. Your choice of view is remembered.

5. Approvals

If your workspace requires approval, a post composed by a team member lands in Waiting for approval and cannot be scheduled until an admin approves it. Editing an already-approved post sends it back for approval — otherwise approving and then rewriting would sidestep the check entirely.

Three things worth knowing

A scheduled video is kept until it goes out. Video files are held for the post that needs them rather than being added to your Content Library — a large file you use once should not live in a library you browse. Scheduling a post extends how long its video is kept, so a post scheduled six weeks out still has its video on the day it publishes. Images are different: they go into the Content Library and stay there permanently.

Daily limits are handled for you. Instagram allows 100 published posts per rolling 24 hours and Threads 250. If you hit one, Solstral waits and publishes when the window frees up rather than failing the post.

X charges per post. Since February 2026, X bills for every post published through its API — and considerably more when the post contains a link. The composer shows the cost before you schedule, and copy longer than 280 characters becomes a thread, with each part billed separately.
