+title: "Set up email notifications from your changelog RSS feed"
+sidebarTitle: "RSS email campaigns"
+description: "Send automatic email notifications to subscribers when you publish changelog updates using your RSS feed with Zapier, Make, or other automation tools."
+keywords: ["RSS", "email", "changelog", "Zapier", "Make", "notifications", "campaign"]
+---
+
+Mintlify generates an [RSS feed](/create/changelogs#subscribable-changelogs) for any page that uses `Update` components. You can connect this feed to an automation tool like Zapier or Make to send email notifications whenever you publish a new changelog entry.
+
+## Prerequisites
+
+- A Mintlify changelog page with `Update` components
+- A [Zapier](https://zapier.com) or [Make](https://www.make.com) account (free tiers available)
+- An email service or mailing list (Mailchimp, SendGrid, or the built-in email options in Zapier/Make)
+
+## Find your RSS feed URL
+
+Your RSS feed URL is your changelog page URL with `/rss.xml` appended. For example, if your changelog is at `https://docs.example.com/changelog`, your RSS feed is at:
+
+```
+https://docs.example.com/changelog/rss.xml
+```
+
+To verify, open the URL in your browser. You should see an XML document with your changelog entries.
+
+<Tip>
+  Add `rss: true` to your changelog page frontmatter to display an RSS icon button that links to the feed. See [subscribable changelogs](/create/changelogs#subscribable-changelogs) for details.
+</Tip>
+

+    2. Select **New Item in Feed** as the trigger event.
+    3. Paste your RSS feed URL (for example, `https://docs.example.com/changelog/rss.xml`) into the **Feed URL** field.
+    4. Click **Test trigger** to confirm Zapier can read your feed.
+  </Step>
+  <Step title="Set up the email action">

+
+    **Option A: Send a simple email notification**
+    1. Search for **Email by Zapier** as your action app.

+    3. Fill in the email fields:
+       - **To**: The recipient email address (or a distribution list)
+       - **Subject**: Use the RSS item title from the trigger data, for example: `New update: {{title}}`

+    3. Connect your email account.
+    4. Map the RSS fields to the email fields:

+## Test your setup
+
+1. Add a new `Update` component to your changelog page and deploy the change.
+2. Wait for the automation tool to check your feed (or trigger a manual run).
+3. Confirm the email arrives with the correct content.
+
+<Note>
+  RSS feed entries contain plain Markdown only. Components, code blocks, and HTML elements are excluded. Use the `rss` property on your `Update` components to provide alternative text for subscribers. See [subscribable changelogs](/create/changelogs#subscribable-changelogs) for details.
