What Postellum publishes to Mastodon
- Posts on any Mastodon server
- Up to 4 photos with descriptions, or one video

Mastodon limits Postellum follows
| What | Limit |
|---|---|
| Text | your server's limit, usually 500 characters |
| Hashtags | up to 10 |

When a post is longer than a platform allows, Postellum shortens it at a sentence or word boundary for that platform only and shows the result in the preview.
