It started with a problem I couldn’t ignore: emails I sent were vanishing. Not bouncing loudly. Not landing in spam with a clear flag. Just… gone. Client follow-ups. Password resets. Internal updates. I had no reliable way to know if the message left my server, reached the recipient’s provider, or died somewhere in between.
Most people shrug at email delivery. I couldn’t. Email is infrastructure. When it fails quietly, everything built on top of it fails quietly too — support tickets, revenue, trust.
The problem was real, not theoretical
I wasn’t building a startup pitch. I was debugging my own workflow. I kept asking the same questions:
- Did the message leave my server?
- Did the recipient’s provider accept it?
- Was it filtered after acceptance?
- Was my DNS configuration actually correct — or just “good enough”?
Existing tools either cost money I didn’t want to spend on a side problem, required accounts I didn’t need, or gave me a score without explaining why something failed. I wanted clarity, not a dashboard badge.
Three weeks of R&D — no monetization plan
I gave myself three weeks. Not to ship a product. To understand the system.
I mapped the delivery chain: SMTP handshake, SPF, DKIM, DMARC, reputation signals, content filtering, provider-specific behaviour. I tested edge cases. I broke things on purpose. I documented what actually mattered versus what people repeat in blog posts without verifying.
At the end of those three weeks, I had something I didn’t plan for: a tool I wished had existed when I started. checkemaildelivery.com — free, no signup wall, built for people who need answers fast.
What I deliberately didn’t build
No paywall. No “free trial” that becomes a subscription. No upsell funnel disguised as a diagnostic.
That wasn’t generosity for its own sake. It was a design constraint. The people who need this tool are often mid-crisis — deliverability broken, client angry, clock running. Adding friction at that moment would have been the wrong product.
What I learned about building for pain
Three things stuck with me:
- Build from your own failure first. If you haven’t felt the problem, you will underestimate what “simple” means to someone in the middle of it.
- Free doesn’t mean cheap. It means you chose a different success metric — usefulness, trust, compound reputation.
- Tools become solutions only in context. A diagnostic tool is useless without readable output. I spent as much time on explanation as on detection.
The best side projects don’t start as products. They start as annoyances you refuse to live with.
What’s next
CheckEmail keeps evolving — more checks, clearer reports, better defaults. I’m not optimising for growth charts. I’m optimising for the next person staring at a silent inbox wondering what went wrong.
If you’ve ever sent something important and never knew if it landed — you already understand why this exists.
