+Use the Email plugin to send an email to a recipient list when a build completes. The following parameters are used to configuration the email plugin:
+
+* **from** - sends email from this address
+* **host** - smtp server host
+* **port** - smtp server port (defaults to `587`)
+* **username** - smtp server username
+* **password** - smtp server password
+* **recipient** - list of email recipients (defaults to commit email)
+
+Same email configuration:
+
+```yaml
+notify:
+  email:
+    from: noreply@github.com
+    host: smtp.mailgun.org
+    port: 587
+    username: octocat
+    password: 12345
+    recipients:
+      - octocat@github.com
+```
