Great news! We’ve just made it even easier to stay on top of your WordPress email delivery. WP Mail SMTP 4.4 now brings you Push Notification Alerts – the most convenient way yet to catch email issues instantly.
Failed emails can cost you sales, damage customer relationships, and create frustrating support issues. Every minute you’re unaware of an email problem puts your business at risk.
Many of our users already benefit from instant email failure alerts through Slack, Discord, and Microsoft Teams. Now we’ve taken it a step further by creating alerts that work directly in your phone or browser – no additional apps required.
With push notifications, alerts appear instantly on the devices you already use every day. One simple setup, and you’ll receive immediate notifications about email failures, even when you’re away from your desk.
The Simplest Way to Stay Informed About Email Issues
What makes push notifications so powerful is their accessibility for everyone. You don’t need to:
- Be an active Slack, Discord, or Teams user
- Constantly check your email inbox
- Pay for SMS messages
- Set up technical webhook integrations
Push notifications work with what you already have: your browser or smartphone. Simply enable them once, and you’ll instantly know when an email fails, whether you’re at your desk or on the go.

They’re perfect for busy site owners who want straightforward alerts without adopting additional platforms.
Never Miss a Critical Email Failure Again
Let’s face it, when your site’s emails fail, it’s more than just a technical glitch.
It means customers aren’t getting order confirmations, users can’t reset passwords, and important notifications aren’t being delivered.
Every minute an email problem goes undetected puts your business and reputation at risk.
With our new Push Notifications Alerts, you’re instantly aware when an email fails, even if you’re nowhere near your WordPress dashboard.
You’ll receive popup notifications right on your desktop or mobile device the moment something goes wrong, giving you the power to resolve issues before they impact your customers.

Set Up Push Notifications in Seconds
Adding push notifications to your alert system couldn’t be easier. Simply navigate to the Alerts tab in your WP Mail SMTP settings, toggle on Push Notification Alerts, and click Enable push notifications on this device.

After allowing notifications in your browser, you’re all set! The best part? You can enable this on multiple devices with the same simple process, creating a network of alerts that keeps you informed no matter where you are.
Each device appears with its own connection name, which you can customize for easy identification.
Looking Ahead
Push Notification Alerts came directly from seeing how our users manage their websites and thinking “how can we make this even easier?”
This new feature joins our existing lineup of alert options that includes Email, Slack, Discord, Microsoft Teams, SMS via Twilio, and Webhooks. Together, they provide a complete notification system to ensure you never miss critical email failures.
What’s next? We’ve got some more cool improvements in the pipeline that we can’t wait to share with you. In the meantime, update to WP Mail SMTP 4.4 today and give push notifications a try. We’d love to hear what you think.
Stay tuned for more updates soon!
