Schedule this week’s updates to Mastodon

**Checked with Postpone**

Four posts are scheduled on your instance:

- Monday and Thursday, the two release notes
- Wednesday, the link to the write-up with a summary above it
- Saturday, the photo from the meetup

They post from the account you connected. Nothing has gone out yet.

## **Schedule Mastodon Posts with AI**

### Post to Your Instance on a Schedule

Connect Postpone to Claude, ChatGPT, or whichever AI you already use, and it can write and queue posts to your Mastodon instance without you opening the web client.

It runs on Postpone’s MCP server, so there is nothing to install and nothing to build. It reads your calendar back before it changes anything, and everything it schedules is in the same Postpone you already use.

> ### What used to take an hour now takes 5 minutes.
>
> I manage social media across eight social platforms. Before Postpone I was posting manually to each one, which was time-consuming, frustrating, and inefficient. I researched nine or ten tools, including Buffer and Hootsuite, and Postpone stood out immediately for its affordability, platform support and intuitive workflow.
>
> Postpone has transformed how I work. I can now craft a post once, select the platforms I want, add images or video with alt text, schedule it, and it’s done in minutes. What used to take an hour now takes five minutes. For a small, volunteer-driven party with limited resources, that kind of time saving is priceless.

## **Mastodon Scheduling FAQs**

What Fediverse Posters Ask Us First

Which servers Postpone connects to, how Mastodon counts characters and links, and what you can set on a post before it goes out.

Still have questions? Check out our help center for answers to most of your questions, or reach out to our support team.

[**Visit the Help Center **](https://help.postpone.app/) [**Contact us **](https://www.postpone.app/contact)

### **Which Mastodon servers does Postpone work with?**

Any of them. Pick your server from the list of popular ones — mastodon.social, mastodon.world, mas.to and the rest — or type in a custom server URL and authorize Postpone there. There is no central Mastodon API to go through, so the connection is made against your own instance and nowhere else.

Pixelfed accounts connect the same way, either from the server list or as a custom URL. The one difference is threading: a Pixelfed account can schedule single posts only.

[**Connecting a Mastodon account **](https://help.postpone.app/platforms/mastodon/connecting-mastodon)

### **How does Mastodon count characters, and what happens to links?**

A post is 500 characters, and a URL always counts as 23 of them no matter how long the actual link is. A mention counts only the username, not the domain after it — so @someone@a-very-long-instance.example costs you far less than it looks.

That leaves more usable room than the number suggests for link-heavy posts. Anything genuinely longer becomes a thread: threads hold as many posts as you want, all of them publish at the same scheduled time, and you can reorder them and turn on automatic numbering before you schedule.

[**Scheduling Mastodon posts **](https://help.postpone.app/platforms/mastodon/scheduling-posts)

### **Can I set visibility, a content warning and a language ahead of time?**

All three are part of the scheduled post. Visibility can be Public, Unlisted (visible to anyone but kept out of public timelines), Private (followers only) or Direct (only the people mentioned). A content warning hides the body behind whatever text you write until a reader chooses to open it. Setting the post language helps it reach people using the language filters on Mastodon. Postpone applies whatever you picked at publish time, so an unlisted follow-up stays unlisted even though you queued it a week earlier.

[**Visibility, content warnings and language **](https://help.postpone.app/platforms/mastodon/scheduling-posts)

### **What can I attach to a Mastodon post?**

Up to 20 images, or one video, or one GIF — and you cannot mix those types in a single post. Images are jpeg, png, webp or heic up to 16 MB and are reduced automatically if they are larger; video is mp4, mov or webm up to 99 MB. Because every instance sets its own configuration, the exact ceilings can vary slightly from one server to the next.

[**Mastodon media limits **](https://help.postpone.app/platforms/mastodon/media-limits)

### **Can Postpone boost my own posts automatically?**

Yes — Auto-Repost is a boost on Mastodon. Set a delay in hours or days when you schedule the post, and Postpone boosts it once the timer runs out, optionally once a day for up to 14 further days so it keeps surfacing for followers in other time zones. If you run more than one connected Mastodon account, the boost can come from a different one.

Auto-Remove is the other half: delete the post after a set time unless it has picked up a minimum number of favourites. Both can be cancelled from your submitted posts before they run.

[**How auto-repost works **](https://help.postpone.app/scheduling/tools/auto-repost)

### **Which Mastodon metrics does Postpone track?**

Favourites, replies, boosts and total engagements, followed over time per post and per account. Views, engagement rate and link clicks are not part of it — Postpone reports those on the platforms that hand them back, and Mastodon does not, which is the honest trade-off of a network with no central analytics service behind it.

[**Which metrics each platform reports **](https://help.postpone.app/scheduling/analytics/post-metrics)

### **What happens if my instance is down when a post is due?**

The post fails rather than disappearing, and it does not cost you anything. Failed submissions are collected under History > Failed Posts and are not counted against your monthly post limit, so a server outage or an expired authorization doesn't quietly eat your allowance. Postpone also notifies you when a connected account loses its connection, so you can reconnect and reschedule rather than finding out a week later.

[**How post limits are counted **](https://help.postpone.app/scheduling/publishing/post-limits)

### **Can I bulk-import Mastodon posts from a spreadsheet?**

Not currently. Bulk Import covers Reddit, X, Threads, Instagram, Bluesky, TikTok, YouTube and Facebook, and Mastodon is not one of them yet.

The closest thing is an account schedule: set your preferred posting days and times once, and every new Mastodon post is auto-filled with the next open slot, so you can queue up weeks of content without picking a date each time. The GraphQL API is the other route if you want to script it.
