Schedule instead of posting now

Tick a time in the same dialog, then manage what is waiting — and read what has already gone out, which stays as a record.

In the same dialog, tick Schedule for later and pick a time. Nothing is sent until then.

Scheduled posts live under Account → Scheduled posts, with what they will publish to and when.

You can cancel anything that has not gone out yet. Posts that have already been sent stay in the list as a record rather than disappearing, so you can see what went where.
