How to Auto-Post Bluesky and Mastodon Posts to Telegram, Discord and WhatsApp

Bluesky and Mastodon have become home for a lot of writers, developers, artists and niche communities. If you post there regularly, you probably also have an audience somewhere else: a Telegram channel, a Discord server, a WhatsApp group or channel, or followers on other social networks. Copying every post by hand gets old fast. This guide explains how to share your Bluesky and Mastodon posts to those places automatically, and what to think about before you switch it on.

Why share decentralised posts somewhere else?

Bluesky and Mastodon are great for conversation, but most people in your wider audience are not on them. Your Discord members live in Discord. Your customers may only check WhatsApp. Your newsletter readers might prefer a quiet Telegram channel. Reposting lets you:

• Write once. Keep posting where you enjoy posting, and let your other channels stay active without extra work.
• Reach people where they already are. Nobody has to sign up for a new app just to follow you.
• Keep communities fresh. A Discord server or WhatsApp group that gets regular updates feels alive, and members are more likely to join in.
• Avoid forgotten channels. Many creators open a Telegram channel, post twice, then forget about it. Automation keeps it going.

How auto-posting from Bluesky and Mastodon works

The idea is simple. You connect a source, such as your Bluesky profile or a Mastodon account, and choose one or more destinations. When a new post appears on the source, it is picked up and published to each destination you selected.

With Synn Media Auto Post, sources can include Bluesky, Mastodon, X, Reddit, YouTube, Telegram and any RSS feed. Destinations include WhatsApp channels and groups, Telegram, Discord and social networks connected through Buffer. Pictures, text and videos are supported. Videos that are too big or longer than three minutes are posted as a link instead, so your destination still gets the update.

Step by step: setting it up

1. Pick your source. Decide which account you want to share from. It can be your own Bluesky or Mastodon profile, or a public account you have permission to repost.
2. Choose where it should go. Add the Telegram channel, Discord channel, WhatsApp channel or group, or Buffer profile you want to post to. Each one needs to be connected once; the Synn Media dashboard has short guides for Telegram and Discord.
3. Set filters. Not every post belongs everywhere. Use filters so only the posts you want get shared, for example skipping replies or posts that contain certain words.
4. Adjust the format. Decide how the post should look on the destination, such as whether to include the original link or keep just the text and media.
5. Turn it on and watch the first few posts. Check that the first shared posts look right, then let it run.

Tips for each destination

Telegram

Telegram channels work well for one-way updates. Reposted Bluesky or Mastodon posts read naturally there, and followers get a notification without being flooded with chat. If your posts include images, they come through as proper media rather than just links.

Discord

Discord servers usually have many channels. Create a dedicated channel such as #updates or #from-bluesky so automated posts do not interrupt live conversations. Members who want your updates can follow that channel, and everyone else can mute it.

WhatsApp channels and groups

WhatsApp is where many small businesses and communities talk to customers. A WhatsApp channel is a good fit for broadcast-style updates. For groups, be considerate: frequent automated messages can feel like spam to members. Share only your most relevant posts to groups, and keep the rest for channels.

Buffer and other social networks

If you also run accounts on other networks, connecting Buffer lets your Bluesky or Mastodon posts flow on to those profiles as well. This is handy if Bluesky is where you write first and the other networks are secondary.

Things to keep in mind

• Respect content ownership. Repost your own content, or content you clearly have permission to share. Credit the original author when sharing from someone else.
• Mind the character limits. Bluesky posts are short, Mastodon posts can be longer. Most destinations handle both, but check that long posts still read well.
• Do not over-post. If you post dozens of times a day on Bluesky, consider filtering so only your best posts reach WhatsApp or Discord.
• Keep it human. Automation saves time, but your community still values real replies. Pop into your Discord or Telegram now and then to answer questions.

Who this is useful for

• Creators and writers who prefer Bluesky or Mastodon but want their Telegram or Discord audience to see every new post.
• Open-source projects and developer communities that announce releases on Mastodon and want the same news in their Discord server.
• Small businesses that share updates on Bluesky and want customers on WhatsApp to get them too.
• Community admins who curate news from several accounts into one Telegram channel or WhatsApp channel.
