How to create and schedule Mastodon threads

DesktopStart

To create and schedule Mastodon Threads with Publer:

• Go to Create page and select Mastodon on the left.
• Start composing a new post.

1. Add a spoiler or warning to your post (optional).
2. Specify the language of the Mastodon post (optional).
3. Click on Make a thread to start creating your thread/reply.

• Tap on the follow-up comment icon.

• Toggle on the button Make a thread.
• Then, if you want to add a delay for the first follow-up post, use the “Is older than” condition (formerly called "Delay") to specify when it will be posted by clicking “Add Conditions”.

• From there, you can choose how long you want to delay it for.

• (OPTIONAL) You can set follow-up comments to be automatically posted based on the performance of the previous post. For example, a follow-up comment can be triggered if the previous post engagements exceed the values you specify.

• To continue adding posts to the thread, click the small + icon below the comment: Add another comment.

• The second follow-up comment can be scheduled based on the previous post if any specific condition is also enabled.
• To add media, simply click on Click to upload media and choose the media you want to add.

• Once you have finished creating the follow-up comments and your thread is ready, simply click on Save and proceed with scheduling the post accordingly.
• You can also preview what the Mastodon thread will look like when it's posted.

Keep in mind:

• You can add up to 25 posts in a Mastodon thread.
• You can specify the language of the Mastodon post and also add a spoiler or warning (optional).
• Each follow-up comment/reply is customizable with text formatting tools, emojis, hashtag suggestions, and media files.
• Each follow-up reply will have a 500 character limit. Publer will notify you by highlighting the text that's surpassed the limit.
• Each follow-up reply will get shared after the previous one. For example, you can't schedule the third reply of a thread to be posted before the second one.
