Show HN: End-to-end monitoring of email sending systems

I built wasitsent.com to alert you when automated emails fail to send. It’s built for DevOps, Marketing Ops, and RevOps teams or anyone else responsible for sending email. I am an engineer and engineering leader with over 20 years of experience building and overseeing SaaS applications. This tool solves a pain point that previously required custom-coded solutions.

I built [wasitsent.com](http://wasitsent.com/) because recently, two of my customers complained that their emails stopped sending and it caused a major headache for their business. I've faced this problem myself multiple time in my career. I asked around on some forums and people shared that they had the issue. Heck, IndieHackers had an email sending problem recently.

Almost no one monitors email sending.

System monitoring and APM (application performance monitoring) is important. Things will break. If you notice and react quickly, your customers won’t suffer. There are many uptime monitoring tools, but nothing exists for doing end-to-end checks on emails.

Emails are surprisingly fragile can break for many disconnected reasons — bad code, bad config, expired credit card in your SMTP provider, someone changed your SPF record to add a marketing tool, misconfigured SMTP server, the dev API key snuck into production, misconfigured cron, and many others. What was missing is an end-to-end email sending check.

It’s still at an MVP stage and I am building feverishly. It’s already useful though, so give it a whirl.

All feedback welcome here, or via email at krystian.cybulski@wasitsent.com. In particular, I am curious if the messaging on the homepage explains this service well and what features you would need to use this.
