Once your Mastodon account is connected (see Connecting your Mastodon account to Ocoya), you can write, schedule and publish Mastodon posts alongside your other channels.
Creating a Mastodon post
1. Click Create new in the top-left, then choose New post.
2. Select your Mastodon channel. Your connected profiles appear as avatars above the caption box, each with a small platform badge. Click the one with the Mastodon badge — a selected channel is highlighted with a ring, and hovering shows the profile name. Click again to deselect. You can select several channels at once, or click + to connect another profile.
3. Write your post in the caption field. A live character count appears in the top-right.
4. Switch to the Preview tab to see the post rendered as it will appear on Mastodon.
5. Click Schedule to pick a date, time and time zone — or Post now to publish immediately.
Scheduled posts appear on your content calendar and publish automatically at the chosen time.
Mastodon options: content warnings
When a Mastodon channel is selected, a Mastodon options section appears in the schedule panel with a content warning field. Anything you type there is shown as the warning, and the post body stays hidden behind a "show more" control until a reader chooses to expand it.
Content warnings are a strong cultural norm on Mastodon. They're commonly used for spoilers, politics, distressing news, food, and anything a follower might reasonably want to opt into rather than see in their timeline. Leave the field empty for ordinary posts.
Character limit
Most Mastodon servers allow 500 characters per post, but each server sets this independently and some allow considerably more. Your server's limit is what applies when the post publishes.
Media
Images | Video | |
Maximum per post | 4 | 1 |
Common formats | JPG, PNG, GIF, WEBP | MP4, MOV |
Images and video can't be mixed in the same Mastodon post.
File size limits are set per server, and are often lower than on large commercial platforms.
Links, hashtags and emoji
Links — include https:// so they publish as clickable links. Mastodon counts every link as a fixed number of characters regardless of its real length.
Hashtags — fully supported, and especially useful on Mastodon because discovery relies heavily on them.
Emoji — standard emoji are supported. Server-specific custom emoji are not available from Ocoya.
Troubleshooting Mastodon posting issues
The Schedule button is greyed out
At least one channel must be selected. Check that the Mastodon avatar above the caption box is highlighted with a ring — if all avatars look dimmed, nothing is selected.
Publishing failed
Check that:
Your Mastodon account is still connected under Connections → Channels.
The post is within your server's character limit.
Any attached media is within your server's size limits.
Post published but media is missing
This usually means the file exceeded the server's upload limit. Try a smaller or more compressed file and publish again.
The whole post is hidden behind a warning
A content warning was set in Mastodon options. Clear that field if you want the post to appear in full.
