Different kind of notifications for Oh Dear!

We offer plenty of ways to receive our alerts: email, SMS, Slack, Discord, Webhooks, ...

You can pick the one that you prefer.

Email notifications

By default, problems we find on your websites are alerted via email. They're simple, to-the-point and will give you a list of actual things to check.

You can add as many email notifications as you want, each with the type of notifications they want to receive.

If you add your JIRA or other service desks' e-mail account to your notifications, you'll automatically have an internal ticket for follow-up.

Slack notifications

Add your Slack Webhook in your settings page and we'll send real-time push notifications to your Slack channel of choice to inform you of any issue.

Get notifications for up/down reports, as well as certificate health problems, broken links, mixed content, ...

HipChat integration

Just like Slack, you can get all your alerts directly in HipChat. Get real time insights in the availability of your websites.

Discord notifications

Discord users will be happy to know that they can just add a Discord Webhook and get notifications in their favourite chat app.


With our webhooks, you can link Oh Dear! with any other service. All data is securely encapsulated in a POST call to an HTTP endpoint you control. And we've got extensive documentation to help get you started.

Webhooks are cryptographically signed, you can optionally validate that the data hasn't been tampered with.

Notifications in iPhone, Android & Windows Mobile can be configured via Pushover. Want them on your desktop as alerts instead? That's covered too.

With Pushover, you can get notifications on pretty much any platform you'd like.
