Connecting and refreshing your Mastodon
You can connect multiple Mastodon accounts to Buffer. Connecting Mastodon works slightly differently from other channels. Because Mastodon is decentralized, you’ll need to select your server first and then you’ll be asked to sign into your account to connect it to Buffer. All the other steps will be the same.
To see a step-by-step guide and troubleshooting steps, check out the article: Connect your channels to Buffer. If your connected channel requires a refresh, check out the article Refreshing a channel in Buffer.
Scheduling Mastodon posts
|Features & good-to-knows||Notes|
|Scheduling posts||Checkout our step-by-step guide to scheduling posts on any social channel or peruse Mastodon-specific details below.|
|Tagging / mentions||
You can mention users by typing out their full address, e.g. @email@example.com. For more information, visit our full guide to adding tags (mentions) here.
We are unable to autocomplete or verify usernames at this time.
|Hashtags||You can use a #hashtag to make your post discoverable by anyone searching for that hashtag. Hashtags can contain alphanumeric characters and underscores, but cannot contain numbers only. Learn more about how hashtags work in Buffer here.|
500 characters per post. Learn more about Character limits for each social network here.
📝Although some Mastodon servers have been customized to support a higher number of characters, Buffer can't detect if the server you're posting to has a higher limit than the default, so we use the default.
|Emoji||Although Mastodon supports custom emojis, we only support emoji from our emoji picker at this time.|
If you include links in your post, they must begin with http:// or https://, otherwise they'll be shown as plain text.
All links are counted as 23 characters, no matter how long they actually are, so there is no need to use a link shortener to save characters. In fact, using a link shortener is actively discouraged.
|Daily posting limit||100 posts per 24 hours. Learn more about Daily posting limits here.|
