Cross-posting to social media

You can use Buttondown's automations to automatically cross-post your emails to social media platforms like Bluesky, LinkedIn, Twitter/X, Mastodon, Tumblr, and Arena.

Create a cross-posting automation to get started --- this will set the trigger and name for you. Click Save changes to create the automation, then open its settings page to add actions.

In the Actions section, click the action picker. You'll see the available social media platforms listed under their respective groups. Add one or more:

• Create a Bluesky post --- Requires Bluesky credentials in your newsletter settings.
• Create a LinkedIn post --- Requires a connected LinkedIn account.
• Create a Twitter post --- Requires a connected Twitter/X account.
• Create a Mastodon post --- Requires Mastodon credentials in your newsletter settings.
• Create a Tumblr post --- Requires a connected Tumblr account.
• Create an Arena post --- Requires a connected Arena account and a channel slug.

If a platform isn't connected yet, the action will appear disabled in the picker. Connect the integration from your settings, then return to the automation to add the action.

Each social media action supports template variables for dynamic content. You can use:

• {{ email.subject }} --- The email's subject line.
• {{ email.absolute_url }} --- A link to the web version of the email.
• {{ email }} --- The full email object and its sub-variables.

If you leave the message field blank, Buttondown will use a sensible default based on the email's subject and URL.

You can set each action to post immediately when the email is sent, or add a delay. For example, you might post to Twitter right away but delay the LinkedIn post by an hour.

Click Save changes when you're done.

Since each automation supports multiple actions, you can cross-post to all your platforms from a single automation. Add one action per platform, each with its own timing and message content. There's no need to create separate automations for each platform.
