What a collaborator post is
Instagram's Collab feature lets a post appear on more than one profile. You publish it, the accounts you invited get an invitation, and once they accept, the same post shows on their grid too — sharing the views, likes and comments across both audiences.
You can invite up to 3 accounts per post. That limit is Instagram's, not ours.
How to add collaborators
- Create a post and select your Instagram account.
- In the Instagram options, choose Post or Reel — collaborators aren't available on Stories.
- Type a handle into the Collaborators box, or pick one you've saved before. Saved handles build up into your address book automatically.
- Schedule or publish as normal.
As you type, we check each handle against Instagram and show a green tick if the account was found. A question mark doesn't mean the handle is wrong — private and personal accounts simply can't be looked up, and the invite is still attempted.
Why Instagram sometimes refuses a collaborator
This is the part that surprises people, so it's worth being direct about it.
Instagram applies stricter rules to collaborator invites sent from scheduling tools than it does inside the Instagram app. An account you can happily tag by hand in the app can still be refused when the same invite is sent by Autoposter — or by any other scheduling tool, because every one of them uses the same Instagram interface we do.
Instagram will refuse the invite if the account being invited:
- is set to private
- was created in the last 30 days
- is age-restricted
- has more than two policy violations on its account
- has turned off the setting that lets others invite them to collaborate
- has blocked or restricted the account doing the posting
Instagram doesn't tell us which of these applies — the response is the same in every case. There is also no way to check any of it in advance, which is why a handle can work for weeks and then start being refused without anything changing on your side. That normally means something changed on their account, not yours.
Checking an account's standing
If one of your own accounts keeps being refused, the answer is usually visible inside Instagram:
- Open the Instagram app on that account.
- Go to Settings → Account Status.
- Account Status shows any policy violations, and whether the account is currently restricted or not being recommended to non-followers.
If you're inviting someone else's account, they'll need to check this themselves — it's only visible to the account owner.
What happens when a handle is refused
Your post still goes out. If Instagram names a handle it won't accept, we drop that one handle and publish with the rest, so a single bad collaborator never costs you the post. Any handle that was dropped is listed on the post afterwards, so you can see exactly what happened.
We also email you whenever this happens, so a refused collaborator is never something you only find out about by noticing the tag missing. The email names the handle Instagram refused and confirms your post published as normal. It goes to workspace admins, and to the model's email address if the workspace has one recorded.
If you find a handle is refused every single time, it's usually not worth retrying — the cause is on the invited account and it will keep being refused until that account's standing changes.
Common questions
It works when I tag them in the Instagram app — why not here?
Because the app and the scheduling interface don't follow the same rules. The app is more permissive. This isn't something we can override.
Will they be notified?
Yes — a collaborator invite appears in their notifications and the post only reaches their profile once they accept it.
Can I invite someone after publishing?
Not through Autoposter. Collaborators have to be set when the post is created. You can still add them by hand in the Instagram app afterwards.
Does the handle need the @?
No, it works either way.
