What you can post
What You Can Schedule on Mastodon
How connecting works
Type your server's address, such as mastodon.social, and sign in on your own server's page. SolMarrow never sees your password. Mastodon access doesn't expire, so you won't be asked to reconnect every few weeks.
Text posts
Up to 500 characters on most servers, or more if your server allows it. SolMarrow reads the exact number from your server when you connect.
Image posts
Up to 4 images per post, each with its own alt text, which many people on Mastodon look for before they boost.
Video posts
One video per post. Images and video can't share a post, and the composer tells you before you schedule rather than after.
How it works
From Idea to Published Mastodon Post in Four Steps
- 01
Connect Mastodon
Type your server's address, such as mastodon.social, and sign in on your own server's page.
- 02
Write once, tailor it
Write the post, then adjust the text and media for Mastodon. The preview shows how it will look, and the composer flags anything Mastodon won't accept.
- 03
Schedule or publish
Pick a date and time in your workspace's time zone, publish right away, or save a draft. SolMarrow posts on time, even when you're offline.

Tips
Mastodon tips that make every scheduled post work harder.
Grow on Mastodon
Write alt text for every image
Image descriptions are a strong habit on Mastodon. Many people won't boost images without them, and they make your posts usable for blind and low-vision readers.
Use CamelCase hashtags
Write #WebDesign instead of #webdesign. Screen readers pronounce each word correctly, and the tag is easier for everyone to read.
Let hashtags do the finding
Mastodon has no algorithm pushing posts to strangers, so hashtags and boosts are how new people discover you. Add a few relevant tags to posts you want found.
Your Brand
Talk, don't just broadcast
Accounts that only drop links tend to get little attention on Mastodon. Reply to people, ask questions and join the conversations in your field.
Tailor your cross-posts
Mastodon readers notice posts copied from other networks with broken @mentions or cut-off text. Adjust the Mastodon version in the composer before you schedule.
