Get Notified When a Netlify Build Fails: Push, Email, Slack

The worst way to find out a Netlify build failed is a client asking why the site still shows yesterday's content. A failed deploy is silent by default — Netlify keeps serving the last good version and doesn't chase you down. So the fix is to set up an alert that reaches you where you'll actually see it.

Here's every option, what it costs, and which plan it needs. Verified against the Netlify docs on July 3, 2026.

What are the ways to get alerted about a failed Netlify build?

There are four practical channels: Git provider status checks (free), an HTTP webhook (free), email notifications (Pro), and Slack notifications (Pro). A dedicated app like Netli.fyi adds push notifications that work on any plan. The right one depends on your plan and where you spend your day.

The free options

Git commit statuses and checks. If your site builds from GitHub, GitLab, Bitbucket, or Azure DevOps, Netlify posts the deploy result straight back to your commits and pull requests. On GitHub-connected sites, commit statuses, PR comments, and checks are added by default. A failed deploy shows a red mark on the PR with a link to the deploy log. This is free, it's already on, and it's the best option if you live in pull requests. It's useless if the failure is on a direct push to production and you're not looking at GitHub.

HTTP POST webhook. Under Project configuration > Notifications > Deploy notifications, you can point a "Deploy failed" event at any URL. Netlify sends a JSON payload (optionally signed, so you can verify it came from Netlify) and your endpoint does whatever you want — ping a Discord channel, hit Microsoft Teams, log it. Free on any plan, but you have to build and host the receiving end.

The Pro options

Email notifications. Netlify can email you on a failed deploy, but this feature is available on Pro and Enterprise plans only. If you're on the free plan, the email option won't be there.

Slack notifications. Netlify's app for Slack posts deploy events — including failures — to a channel you choose. This is also a Pro feature. Good for teams that already run everything through Slack, as long as someone's watching the channel.

The push option: Netli.fyi

Email and Slack both assume you're at a desk with that inbox or channel open. The Git status only helps if you're looking at the repo. None of them tap you on the shoulder when you're away from your screen — which is exactly when a build tends to break.

That's the gap Netli.fyi fills. It connects to your Netlify account and sends a push notification to your iPhone the moment a build fails — with the site name and a way to jump straight to the deploy. Two things make it different from the built-in options:

• It works on any plan, including free. It reads your deploy status through your account rather than relying on Pro-only notification features.
• It reaches you anywhere, not just when a specific app is open on a specific screen.

From the same notification you can open the build log, and if the failure was a fluke (a flaky dependency, a cache issue), trigger a redeploy right there.

Never miss a failed build again. Netli.fyi sends a push notification the moment a Netlify build fails — on any plan, wherever you are. Get it on the App Store.

Which should you set up?

• Team living in Slack, on Pro? Turn on Slack notifications.
• Solo dev who wants to know instantly, on any plan? Push, via Netli.fyi.
• Everything goes through pull requests? The free Git status checks may be all you need.
• Comfortable wiring your own endpoint? The free webhook is the most flexible.

Most people I know end up with two: Git checks for the PR workflow, and push for the "I'm not at my desk" case. The point isn't which one — it's that a failed build should never be able to sit quietly for a day.

Android user? Netli.fyi is iPhone-only today, with an Android waitlist open. The free Git and webhook options above work regardless of your phone.
