A useful lesson from this week: write down the questions your customers ask. They are a good place to start your next article.

MicroPoster crossposts it
Your Bluesky account

The same update, published as a native post on Bluesky.

Getting started

Connect Mastodon and Bluesky

  1. 01

    Authorize both accounts

    Connect your Mastodon account through its server and your Bluesky account through Bluesky authorization. Check that each connected profile is the one you intend to use.

  2. 02

    Select the direction

    Create a crossposting automation with Mastodon as the source and Bluesky as the destination. Activate it to pick up supported new source posts.

  3. 03

    Review the Bluesky copy

    Publish a new Mastodon post, then check the result on Bluesky after the next eligible check. Test longer text and supported media before adding more workflows.

What to check between the two networks

Different text limits

Your Mastodon server may allow more text than a single Bluesky post. MicroPoster adapts supported content for Bluesky, including splitting longer text into a native thread where needed.

Handles and attachments

Mastodon handles include a server, while Bluesky accounts use a different identity system. Check that mentions make sense on the destination and that attachments meet Bluesky's requirements.

Independent conversations

Replies, reactions and later edits stay with each post. Crossposting does not merge conversations or keep published copies continuously synchronized.

Questions about this workflow

For help with your accounts, contact us.

Can I crosspost Bluesky to Mastodon instead?

Yes. Create an automation with Bluesky as the source and Mastodon as the destination. Check the destination server's content limits and rules before expanding the workflow.

Is this continuous synchronization?

No. MicroPoster publishes separate destination posts from supported new source content. Later edits and engagement are not synchronized between the networks.

How quickly does automatic crossposting run?

MicroPoster checks for new posts at the interval included in your plan. Crossposting is not instant. Platform availability, media processing and your remaining allowance can affect when a post is published.

Can I keep a post on just one platform?

Yes. Add #nocrosspost or #keephere to the post, or a reply in its thread, to skip it in automatic crossposting. You can still crosspost it manually from your dashboard.

Do I need a credit card to try MicroPoster?

No. New accounts receive a 7-day trial under the Creator plan limits. A trial without payment details does not automatically become a paid subscription. Check Pricing for the current account limits and allowances.
