Easily subscribe to a P2 comment thread without commenting using a “Follow” action link like WordPress.com has.
This plugin requires Jetpack and P2 to both be activated. It doesn’t yet allow you to unfollow, and there are some minor interface quirks.

Let readers subscribe to get email updates whenever you publish new content.
This IS NOT a marketing plugin.
This is purely a utility plugin, allowing your readers to get simple email updates in a more privacy-respecting way. It does not create an email list that you can export in plain text or use for any purpose other than sending notifications from your site. If you’re looking for a more traditional email subscriber plugin, I recommend <a href="https://wordpress.org/plugins/subscribe2/" rel="ugc">Subscribe2</a>, and if you’re looking for a full-blown newsletter service, I recommend <a href="https://mailchimp.com/" rel="nofollow ugc">Mailchimp</a>.
<h4>How it Works</h4>
<ol>
<li>You install and activate the plugin.</li>
<li>You place the <code>[subby]</code> shortcode somewhere on your website and invite users to subscribe/unsubscribe for updates. You can optionally customize the button label: <code>[subby submit="Get Updates"]</code>.</li>
<li>When someone subscribes or unsubscribes via the form, they receive a confirmation email with a link to complete the action.</li>
<li>When you publish new content, confirmed subscribers receive a notification email with a link to the new post.</li>
<li>Subscriber emails are encrypted at rest and only shown partially in the admin (Tools > Subscribers).</li>
<li>The encryption key is derived from your existing <code>AUTH_KEY</code> found in your wp-config.php file.</li>
<li>In your admin (Tools > Subscribers), you can manage subscribers and configure the from name and email, which post types trigger notifications, and which categories to exclude.</li>
</ol>
