Can Socialync post a first comment?
Yes, on Instagram, Threads, X, YouTube, LinkedIn, and Bluesky. You can queue up to 5 first comments on one post. They post in order right after the post goes live, and each platform can have its own list.

How first comments work
- Add up to 5 comments in the composer. They go out in the order you list them, one at a time with a short pause, once the post is published.
- In the platform settings you can give a platform its own list instead of the shared one.
- Through an AI assistant you can change the first comment of a scheduled post before it goes out.
Length limits

| Threads | 500 |
| X | 280 |

| 1,250 | |
| Bluesky | 300 |
