+
+<p>
+  Here's your options for receiving updates about new blog posts:
+</p>
+
+<h2>Option 1: Email</h2>
+
+<p>
+  Email is by far my preferred option for notifying followers of new posts.
+</p>
+
+<p>
+  The entire email list system for this blog, from storing subscriber email
+  addresses to the email server which sends the notifications out, has been
+  designed from scratch and is completely self-hosted in my living room.
+</p>
+
+<p>
+  I solemnly swear that:
+</p>
+
+<ul>
+
+  <li>
+    You will never receive an email from this blog except to notify of a new
+    post.
+  </li>
+
+  <li>
+    Your email will never be provided or sold to anyone else for any reason.
+  </li>
+
+</ul>
+
+<p>
+  With all that said, if you'd like to receive an email everytime a new blog
+  post is published then input your email below and smash that subscribe button!
+  You will need to verify your email, so be sure to check your spam folder to
+  complete the process if you don't immediately see anything in your inbox.
+</p>
+
+<style>
+
+#emailStatus.success {
+    color: green;
+}
+
+#emailStatus.fail {
+    color: red;
+}
+
+</style>
+
+<input type="email" placeholder="name@host.com" id="emailAddress" />
+<input class="button-primary" type="submit" value="Subscribe" id="emailSubscribe" />
+<span id="emailStatus"></span>
+
+<script>
+
+const emailAddress = document.getElementById("emailAddress");
+const emailSubscribe = document.getElementById("emailSubscribe");
+const emailSubscribeOrigValue = emailSubscribe.value;
+const emailStatus = document.getElementById("emailStatus");
+
+emailSubscribe.onclick = async () => {
+
+    const api = await import("/assets/api.js");
+
+    emailSubscribe.disabled = true;
+    emailSubscribe.className = "";
+    emailSubscribe.value = "Please hold...";
+    emailStatus.innerHTML = '';
+
+    try {
+
+        if (!window.isSecureContext) {
+            throw "The browser environment is not secure.";
+        }
+
+        await api.call('/api/mailinglist/subscribe', {
+            body: { email: emailAddress.value },
+            requiresPow: true,
+        });
+
+        emailStatus.className = "success";
+        emailStatus.innerHTML = "Verification email sent (check your spam folder)";
+
+    } catch (e) {
+        emailStatus.className = "fail";
+        emailStatus.innerHTML = e;
+
+    } finally {
+        emailSubscribe.disabled = false;
+        emailSubscribe.className = "button-primary";
+        emailSubscribe.value = emailSubscribeOrigValue;
+    }
+
+};
+
+</script>
+
+<h2>Option 2: RSS</h2>
+
+<p>
+  RSS is the classic way to follow any blog. It comes from a time before
+  aggregators like reddit and twitter stole the show, when people felt capable
+  to manage their own content feeds. We should use it again.
+</p>
+
+<p>
+  To follow over RSS give any RSS reader the following URL...
+</p>
+
+<p>
+  <a href="{{ BlogURL "feed.xml" }}">{{ BlogURL "feed.xml" }}</a>
+</p>
+
+<p>
+  ...and posts from this blog will show up in your RSS feed as soon as they are
+  published. There are literally thousands of RSS readers out there. Here's some
+  recommendations:
+</p>
+
+<ul>
+  <li>
+    <a href="https://chrome.google.com/webstore/detail/rss-feed-reader/pnjaodmkngahhkoihejjehlcdlnohgmp">
+      Google Chrome Browser Extension
+    </a>
+  </li>
+
+  <li>
+    <a href="https://f-droid.org/en/packages/net.etuldan.sparss.floss/">
+      spaRSS
+    </a>
+    is my preferred android RSS reader, but you'll need to install
+    <a href="https://f-droid.org/">f-droid</a> on your device to use it (a
+    good thing to do anyway, imo).
+  </li>
+
+  <li>
+    <a href="https://ranchero.com/netnewswire/">NetNewsWire</a>
+    is a good reader for iPhone/iPad/Mac devices, so I'm told. Their homepage
+    description makes a much better sales pitch for RSS than I ever could.
+  </li>
+</ul>
