Scheduling Mastodon Posts

Learn how to schedule individual Mastodon posts and threads from your connected accounts.

With Postpone, you can schedule Mastodon posts and threads in advance so that your content continuously appears in your followers' feeds.

Post Specifications

  • Character limit: Each post can have up to 500 characters.
  • Media support: Each post can contain up to 20 images, or 1 video, or 1 GIF. You cannot mix media types.
URLs in Mastodon posts always count as 23 characters regardless of their actual length. Mentions only count the username portion, not the domain.

Threads

  • Threads can contain unlimited posts.
  • All posts in a thread are scheduled for the same date and time.
  • You can reorder posts within a thread and use thread numbering.
Threading is not available for Pixelfed accounts.

  • Link image attachment — Pull the preview image from a link in your post and attach it as media with one click.
  • Alt text — Add a description to each image so screen readers can describe it.
  • Visibility — Publish as public, unlisted (visible to everyone but kept out of public timelines), followers-only, or as a direct post to mentioned users.
  • Content warnings — Add warning text that hides the post body until a viewer chooses to reveal it.
