Yes, Threads posts can be scheduled and published automatically.
What Threads accepts
Through BulkPublish:
| Post length | 500 characters |
| Post types | Text, Image, Video, Carousel |
| Images | Up to 20 per post, 8 MB each, JPG or PNG |
| Video | Up to 500 MB, MP4 or MOV |
| Threads | Supported |
Two things stand out. Text-only posts are fine, unlike Instagram where every format needs media. And 20 images per post is unusually generous for a short-text network.
500 characters is the comfortable end
Among the short-text platforms, Threads is joint-most generous:
| Platform | Limit |
|---|---|
| X | 280 |
| Bluesky | 300 |
| Threads | 500 |
| Mastodon | 500 |
That means anything written for X or Bluesky publishes to Threads unchanged. The reverse isn’t true: a 500-character Threads post gets cut on the other two.
So if Threads is one of several destinations, the decision is whether to write to the tightest limit once, or write the fuller Threads version and compress for the others. The second is better and costs a minute.
Threading
Supported, and less necessary here than on X or Bluesky, because 500 characters holds a complete thought more often.
The usual rule applies: thread when the idea genuinely needs the room, not out of habit. And the first post has to work alone, since it’s the one that gets seen.
Scheduling one
- Connect your Threads account
- Write within 500 characters
- Add media if you want it, up to 20 images or a video
- Pick a date and time and queue it
The character count is enforced as you type and media rules are checked before queueing, so nothing gets truncated or rejected at publish time.
What doesn’t cross-post
Replies. A post that only makes sense as a response to something on Threads means nothing elsewhere.
Mentions. Handles differ per platform. An @name carried across usually points at someone unrelated, or nobody.
Plan limits
BulkPublish publishes to Threads and 14 other networks.
- Channels: Free: 3 (1 per platform). Pro: 30 (2 per platform). Business: 75 (5 per platform).
- Posts: Free: 3/day. Pro: 30/day. Business: unlimited.
- Storage: Free: 100 MB. Pro: 2 GB. Business: 10 GB.
Short answer
Yes. 500 characters, text-only posts allowed, up to 20 images or a 500 MB video, threading supported. Anything written for X or Bluesky posts here unchanged, so Threads is usually the easiest platform to add to an existing short-text workflow.
