It is built for writers who chose Buttondown for its simplicity and want promotion to be just as simple: an email you already send becomes the week's social posts. [**Get Started for Free**](https://www.postpone.app/signup) ## **Auto-Share Buttondown Issues** ### Share Every New Issue Without Retyping It Paste your newsletter's Buttondown address and every issue you send shows up in Postpone on its own, with its title and link ready to post. No key and no login handed over. Post one yourself, or hand the whole job to an [**automation**](https://www.postpone.app/features/social-media-automation) and let each issue promote itself. ## **Social Post Templates for Buttondown** ### Write the Post Once and Let Every Issue Fill It In Write the announcement once, the way you would write it yourself, and every new Buttondown issue fills it in with its own title, link and summary. Each platform gets its own version, a thread here and a short note there, and a live preview shows what will go out before you save. ## **Buttondown Social Media Automation** ### Decide How Much Each Issue Posts on Its Own Choose how much each Buttondown issue does on its own: the post can wait as a draft for a read-through, go out on a delay you set, or publish as soon as Postpone sees the issue. Pause the automation whenever you like, and the run history shows every post that did not go out, and why. ## Everything Postpone Does With a New Issue Six things Postpone can do with a new issue, all from the feed it already reads. - ### One Issue, a Post for Every Platform A single automation holds several actions, each aimed at one account with its own template. The same issue can read as a hook on X, a summary on LinkedIn and a one-liner on Bluesky, all from the same run. - ### Threads, Not Only Links On X, Bluesky, Threads and Mastodon a template can be a thread. Open with the issue's title, pull its summary into the middle and end on the link, so the post says something before it asks for a click. - ### Timing That Suits Each Platform Give each action its own delay. Publish to Bluesky as the issue sends, wait until the next morning for LinkedIn and hold X for the afternoon, all from one issue and one automation. - ### Review Before Anything Goes Out Set an action to draft rather than publish and the post waits in Drafts. Change the wording, add an image, then schedule it yourself. Nothing publishes until you say so. - ### Let the AI Write the Post From the Link Paste an issue's link into Postpone's AI writer and it reads the archive page and drafts a post or a whole thread from it, in the tone you have set for that platform. - ### See How Each Post Performs on Social Every post an automation publishes shows up in analytics like any other, so you can compare posts by likes, replies and impressions and see which platform your subscribers are actually on. ## Seven Platforms From One Buttondown Feed An automation schedules posts to these platforms on its own. - [**X**Posts and threads](https://www.postpone.app/platforms/twitter-post-scheduler) - [**LinkedIn**Profiles and Pages](https://www.postpone.app/platforms/linkedin-scheduler) - [**Bluesky**Posts and threads](https://www.postpone.app/platforms/bluesky-post-scheduler) - [**Threads**Posts and threads](https://www.postpone.app/platforms/threads-scheduler) - [**Mastodon**Posts and threads](https://www.postpone.app/platforms/mastodon-post-scheduler) - [**Facebook**Pages](https://www.postpone.app/platforms/facebook-post-scheduler) - [**Reddit**Posts to a subreddit](https://www.postpone.app/platforms/reddit-post-scheduler) Need Instagram, TikTok or YouTube Shorts as well? The [**Zapier integration**](https://www.postpone.app/integrations/zapier) schedules to those from any trigger Zapier supports, and the [**Postpone API**](https://www.postpone.app/features/social-media-api) reaches all twelve platforms. ## Connect Buttondown to Postpone in Three Steps Set it up once and every issue you send promotes itself. 1. 1 ### Add your newsletter as a feed Turn on the RSS feed for your newsletter and point Postpone at it, and it watches for new issues with no key to generate. 2. 2 ### Build the automation Write one template per platform from the issue's title, link and summary, then choose whether each post drafts, schedules itself or publishes right away. 3. 3 ### Send your next issue Postpone spots the new issue and fills your template, so the posts land as drafts, on your calendar or live without a separate promotion pass.

Still have questions? Check out our help center for answers to most of your questions, or reach out to our support team. [**Visit the Help Center **](https://help.postpone.app/) [**Contact us **](https://www.postpone.app/contact) ### **How does Postpone share a new Buttondown issue?** Postpone tracks your Buttondown newsletter as a feed and an automation turns each new issue into social posts. The template you write once pulls the issue's title, its link and its summary, so an email you already send becomes a week of social posts with nothing retyped. [**How automations work **](https://www.postpone.app/features/social-media-automation) ### **Does connecting Buttondown need an API key?** No, Postpone reads the RSS feed your newsletter publishes once you enable it, so there is no key to generate and no account access to grant. Adding the newsletter address is the whole setup, and deleting the feed is the whole teardown. [**Every supported feed source **](https://help.postpone.app/content/feeds/supported-feed-sources) ### **Why does Postpone say my Buttondown feed has no items?** Buttondown only publishes a feed once the newsletter's owner has enabled RSS. Turn RSS on in your Buttondown settings, then use Fetch Latest on the feed in Postpone and the issues appear. [**Automation troubleshooting **](https://help.postpone.app/scheduling/automation/troubleshooting) ### **Can I check what Postpone will post before it posts it?** Yes, twice over. The action editor previews your template against the most recent issue in the feed, so you see the real post before saving the automation. And an action set to draft leaves each generated post in your Drafts list, where nothing publishes until you approve it. [**The social media scheduler **](https://www.postpone.app/features/social-media-scheduler) ### **How long after I send an issue does the post go out?** Postpone checks your Buttondown feed on a schedule rather than the instant you hit send, so there is a short delay before the automation runs. Feeds are polled, not pushed. After that it depends on the action. A submitted post publishes as soon as the run starts, and a scheduled post waits for the delay you set, counted from that moment. [**The three action types **](https://help.postpone.app/scheduling/automation/actions) ### **Which platforms can a Buttondown automation post to?** Seven: X, LinkedIn, Bluesky, Threads, Mastodon, Facebook and Reddit. Instagram, TikTok, YouTube Shorts, Pinterest and Tumblr are not available to automations. The Zapier integration reaches the first three of those and the Postpone API reaches all twelve.
