Using Postmark Rebound to improve handling of bounced emails original

by Freek Van der Herten – 2 minute read

Whenever Oh Dear detects something wrong with your site, it can send you a notification. We have multiple channels available: Slack, Telegram, webhooks, and many more. The most popular channel our users use is just simple mail.

Behind the scenes, Oh Dear uses Postmark to send emails. Postmark will inform us whenever a notification mail results in a hard bounce. A hard bounce means that the mail won't be delivered. The most common reason for this is that the mailbox doesn't exist (anymore). This can occur when somebody changes jobs, and the work email address no longer exists.

Determining the start of the next business day in Oh Dear original

by Freek Van der Herten – 9 minute read

When a site is down, Oh Dear sends a notification every hour. Since last year, our notifications can be snoozed for a fixed amount of time (5 minutes, 1 hour, 4 hours, one day).

In the evenings and weekends, our users might not want to receive repeated notifications. That's why we've added a nice human touch: all notifications can now be snoozed until the start of the next workday.

In this blog post, I'd like to share some of the code that powers this feature. We'll focus on how the start of the next workday is calculated.

Why and how you should monitor scheduled tasks original

by Freek Van der Herten – 10 minute read

Oh Dear is the monitoring SaaS that my buddy Mattias and I are running. As you might suspect, our service can monitor the uptime of sites and SSL certificates' health. What sets Oh Dear apart from the competition is that it can also monitor performance and detect broken links and mixed content on any of the pages of your site.

Today, we added a new type of monitoring: scheduled tasks monitoring. Oh Dear can now notify you whenever one of your scheduled tasks has not run or is running too late.

You can get started monitoring your schedule today. We have a free ten-day trial. And when using this coupon code, you'll get 30% off on the first three months when subscribing: MONITOR-ALL-THE-THINGS.

In this blog post, I'd like to introduce how you can use scheduled task monitoring in Oh Dear, and how it works under the hood. There were a lot of interesting challenges we had to solve. I hope you're ready to dig it.
