Schedule Threads Posts
Updated · Multi Post Social guide
You can schedule Threads posts from Multi Post Social: text up to 500 characters, up to 20 images, video, polls and multi-part chains, each with reply controls and a topic tag. Threads is tied to an Instagram account, which shapes how you connect it. This guide covers that link, the connection steps, the limits the composer checks, how reply controls work, and what tends to earn conversation on Threads.
What you can schedule on Threads
Text posts, posts with one or many images, a single video up to five minutes, polls, link posts with a preview and chains of several posts all publish directly at the scheduled time. Each post can carry one topic tag, which Threads uses instead of hashtags, and a reply setting that decides who may answer. Quote posts of another Threads post and reposts are made in the Threads app.

Account requirements
Every Threads profile belongs to an Instagram account, and that is the login you use. The Instagram account can be personal, Creator or Business; Threads does not require a business type the way Instagram publishing does. If you manage several Threads profiles, connect each through its own Instagram login. Threads channels count toward the channel total like any other network.
How to connect Threads
- Open Channels, press Connect channel and choose Threads.
- Sign in with the Instagram account that owns the Threads profile.
- Accept the permissions to publish, read replies and read insights.
- Set the time zone and a posting schedule. Threads conversations run through the day, so two or three slots spread out work well.
Tokens last about 60 days; the channel shows Needs reconnect when one ends and the queue pauses until you sign in again.

Reply controls and topic tags
For every post you choose who can reply: anyone, profiles you follow, or only mentioned profiles. The setting is stored per post, so a question can stay open while an announcement limits replies. A topic tag is a short phrase, not a hashtag, and a post takes one. Pick tags that match how people browse; the listening module shows which topics your mentions use most.
Best practices when you schedule Threads posts
- Write like a conversation starter; questions and opinions earn more replies than announcements.
- Keep chains to three or four parts and put the payoff in the first one.
- Use the topic tag for discovery instead of stacking hashtags in the text.
- Mix text-only posts with images; text alone performs well here.
- Reply within the hour from the inbox; Threads rewards active conversations.
- Repurpose the first line of a LinkedIn post as a Threads post with the AI assistant.
Connection errors and fixes
| Message | Cause | Fix |
|---|---|---|
| Token expired | 60-day expiry or Instagram password change | Press Reconnect and sign in again |
| Profile not found | The Instagram account has no Threads profile yet | Open Threads once with that account, then reconnect |
| Daily limit reached | Threads caps posts through tools per day | The post waits and publishes the next day |
| Media not accepted | Over 8 MB per image or 5 minutes of video | Compress and retry |
| Chain stopped at part N | One part failed | Fix that part and press Retry |
Mobile tips
Threads is a phone-first network, so preview posts on the phone in the Multi Post Social app before they queue. Short text posts are quick to write on the go; save longer chains for the desktop composer.
One more habit that pays off on Threads: reply to the first few comments on your own post within the hour. Threads ranks conversation highly, and a post with a short reply thread under it keeps surfacing for longer. Keep a saved reply or two in the inbox for the questions you get every time, and queue the next post for the day after rather than the same evening, so each one gets its own window.
Threads rules to keep in mind
Threads follows Instagram’s community guidelines and limits how many posts a tool can publish per day. Disclose paid partnerships in the text and avoid repeating the same post across accounts. Meta’s Help Center covers Threads policies.
