FAQ

Mastodon scheduling FAQ

Does Mastodon have native scheduling?

Mastodon's standard web interface has no schedule button, although some apps add one. Social9 schedules Mastodon posts on any server, next to your other networks.

Is the Social9 Mastodon scheduler free?

Yes. The Free plan includes Mastodon: 3 social accounts on LinkedIn, Instagram, Mastodon or Bluesky, 20 AI credits a month and 10 queued posts per account, with no credit card. Paid plans start at $12/mo.

Will Social9 post to Mastodon without asking me?

Only if you turn on Full Autopilot. On Drafts only you publish yourself, and on Approve first every post waits for your OK. Quiet hours and a Pause button work in every mode.

What happens if a Mastodon post fails?

Social9 retries posts that fail for a passing reason and alerts you when one can't be published. If Mastodon needs you to log in again, you get a prompt to reconnect.
