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.

Add a spoiler or warning to your post (optional).
Specify the language of the Mastodon post (optional).
Click +Add to Thread to start building your thread/reply.

You can also click on Split into a thread if you already have a long piece of text. Publer can divide it automatically into multiple tweets using Natural split or Split with AI, making it easier to repurpose long content into a thread. Learn more about it here.

Wrapping a Thread

You can Copy, Wrap, or Delete a thread by clicking the three dots next to it.

To copy text, conditions, media or the entire post, click on Copy and choose one of the available options.

Choose Wrap the thread to preview how the entire thread will appear.

Wrapping adds a final post that highlights the full thread. The last post becomes your wrap up message, bringing the thread back to the top with a final takeaway, note, or link.
Preview how it looks.

If you want to change it back, you can always unwrap the thread.

Delays and Conditions

To keep adding posts to your thread, click +Add to thread under the previous comment.

You can also reorder the posts in your thread by clicking on the Move down or Move up options before publishing. You need to have at least 2 follow-up comments for this option to work.

To add media, click Click to upload media and select the files you want to attach.

If you want to add a delay for the first follow up comment, click the three dots on the left and choose Add Conditions.
You can add conditions to each thread the same way.

In the pop up, use the Is older than condition to specify the delay for the next comment. This is the updated name for the former Delay option.

(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.

NOTE: Follow-up comments can be set to post automatically based on a specific delay or performance. Conditions can be based on Time (Is older than), Reach, and Engagements.

The "Reach" condition is not available for this account due to API limitations.

NOTE: You can add conditions to additional follow up comments. Performance based conditions apply only to the first follow up comment.

Once your thread is ready and all follow-up comments are set, proceed to schedule the post as usual.
You can also preview what the Mastodon thread will look like when it's posted.

WARNING: Threads and follow-up comments do NOT carry over automatically when reusing posts from saved drafts, scheduled content, or previously published posts. Therefore, you will need to manually add them each time.

TIP : You can also set default follow-up comments or threads for all your posts by following this guide.

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.

In the pop up, use the Is older than condition to specify the delay for the next comment. This is the updated name for the former Delay option.

(OPTIONAL) You can set follow up comments to post automatically based on the performance of the previous post. For example, the next comment can trigger only if the earlier post reaches the engagement levels you define.
Click on Save after adding the conditions.

NOTE: Follow up comments can be triggered by a specific delay or by performance. Conditions can be based on Time (Is older than), Reach, and Engagements.

The "Reach" condition is not available for this account due to API limitations.

Once you have finished creating the follow-up comments and your thread is ready, click on the eye icon to preview it.

After that, go back and click on Save and proceed with scheduling the post accordingly.
