RSS + Beehiiv + Substack Integration

Auto-fetch your latest newsletter via RSS URL instead of copy-pasting.

Why Use RSS?

Instead of copy-pasting your newsletter every time, enter your RSS URL once. OnePost fetches the latest issue automatically.

Substack RSS

Your Substack RSS feed is at: `` https://yourname.substack.com/feed

Paste this URL in the Newsletter URL field on the main app page.

Beehiiv RSS

Your Beehiiv RSS feed is at: `` https://yourname.beehiiv.com/feed

Note: Beehiiv sites use Cloudflare protection. OnePost handles this automatically by trying RSS first, then HTML scraping as a fallback.

Other Platforms

• **ConvertKit / Kit:** RSS available in broadcast settings
• **Ghost:** `https://yourdomain.com/rss/`
• **Mailchimp:** RSS-to-email campaigns include a feed URL

RSS Monitor

Go to Settings → RSS Monitor to set up automatic detection of new issues. When a new issue is detected, OnePost can fire a webhook to trigger your Zapier automation.
