Add web push notifications to your WordPress site with EasyPusher. Send browser push notifications to Chrome, Firefox, Edge, Opera, and Safari subscribers — re-engage visitors after they leave, announce new content, drive traffic back to your site, and grow your audience.
EasyPusher takes care of the parts of web push that usually slow you down: VAPID key generation, service-worker installation, cross-browser payload quirks, and subscriber storage. Install the plugin, paste your API Key, and you’re live — the full push pipeline is managed for you in the EasyPusher cloud.
<h4>What you can do</h4>
<ul>
<li>Send web push notifications to all subscribers or to targeted segments</li>
<li>Capture browser subscribers with a customisable opt-in prompt — no coding required</li>
<li>Schedule push notifications in advance, or send them instantly</li>
<li>Track delivery and engagement — sent, delivered, clicked, dismissed, CTR</li>
<li>UTM tracking on every link so push traffic shows up in your analytics</li>
<li>Cross-browser support — Chrome, Firefox, Edge, Opera, and Safari, on both desktop and mobile</li>
<li>Multi-site ready — manage push campaigns across several WordPress sites from one EasyPusher dashboard</li>
<li>Fast CDN delivery — the JS SDK and service worker load from Cloudflare for minimal performance impact</li>
<li>Easy uninstall — the plugin cleans up its WordPress options and removes the service-worker proxy file on uninstall</li>
</ul>
<h4>Common use cases</h4>
<ul>
<li>Content publishers and bloggers — notify subscribers when new articles, podcasts, or videos are published</li>
<li>News sites — push breaking-news alerts to your audience in real time</li>

</ul>
<h4>How it works</h4>
<ol>
<li>Sign up for a free <a href="https://easypusher.com" rel="nofollow ugc">EasyPusher</a> account.</li>
<li>Add your WordPress site in the EasyPusher dashboard and copy the generated API Key.</li>
<li>Install this plugin, go to EasyPusher → Settings, and paste the API Key.</li>
<li>Configure your opt-in prompt in the EasyPusher dashboard (style, copy, trigger).</li>
<li>Visitors see the prompt, click Allow, and start receiving the push notifications you compose from your EasyPusher dashboard.</li>
</ol>
The plugin does three things on your WordPress site: it injects the EasyPusher JS loader snippet into <code><head></code> on public pages, writes a 2-line <code>ep-sw.js</code> service-worker proxy file to your site root on activation, and adds a Stats page to the WP admin that pulls live numbers from your EasyPusher account.
