# Publish an Instagram collab post from Notion

### Publish an Instagram collab post

A collab post shows up on several accounts' feeds at once, with a "Collaboration" badge. You set it all up from Notion, without touching the Instagram app.

### How to invite a collaborator

In your post text, write the collaborator's handle preceded by a **double @**: `@@username`.

* You can invite up to **3 collaborators** per post.
* Separate them with a space: `@@username1 @@username2`.
* At publish time, Scheduled sends the invite and cleans the caption: `@@username` shows up as a plain `@username`.

|| A single `@username` does NOT trigger a collab invite. The double `@@` is the explicit opt-in, so you don't accidentally invite a brand or account you only mention in your text.

### What happens on Instagram

Each collaborator receives a collaboration request. Once accepted, the post also appears on their feed and the accounts' audiences are combined.

### Key takeaways

* Double `@@username` in the text = collab invite.
* Up to 3 collaborators per post.
* Single `@username` = regular mention/tag, no invite.
* The collaborator must accept the request on Instagram.
