Website emails not arriving is a quiet problem. There's no error message and nothing lands in spam. Your contact form alerts, order notices or reports just stop, and you find out when someone asks why you never answered. That's what happened on SportsHallz, my sports Hall of Fame site. Every night it emails me a report on its product listings. After August 16, those emails stopped showing up. Here's what was wrong, how Claude and I fixed it, and what it means for your site.

What We Changed: Mail That Uses the Front Door

Every night, scripts on SportsHallz update its product listings, and each one emails me a report. The site was sending those reports through the web host's built-in mailer. Think of it as mailing a letter with a return address the post office doesn't recognize. We changed it to send through the site's real mail service, with a proper login.

I work through the host's file manager in a browser, so Claude built a one-page checker that tested the new code before it went live. The test message landed in my inbox. By September 8, 208 reports had arrived through the new route.

What This Means for Your Site

A site can look healthy and still be silent. The nightly jobs ran the whole time, and products were still being added every day. Only the emails stopped. Website emails not arriving never shows up on a dashboard. I noticed because the reports weren't there.

"Sent" doesn't mean "delivered." Receiving mail servers check whether a message really comes from where it says. According to Google's sender guidelines, messages that fail those checks "might be marked as spam or rejected." Your contact form can fall into the same trap.

The fix is usually a proper sending account. It's a small change once you know where to look, and I can make it on your site too.

Cleanup hides in the same corner. While we were in there, we found three more problems. The report said "failed" on 99 of every 100 good sends, because of a bug that only reported success by chance. A stray line was scribbling junk into the job's output. And a leftover test file sat in the public web folder with the mail password written inside it. It would send mail for anyone who loaded the page. Nobody sees a file like that until someone else finds it. It's gone now, and the address returns a "not found" page.

What I Still Don't Know

I never found out why delivery stopped on August 16 specifically. The domain's approved-sender record is much older than the problem, and mail arrived fine until that date. Something changed on the receiving end or at the host, and we didn't identify it. The new route is sound either way, but I won't claim I found the original trigger.

Two more limits. A second, smaller mail path on the site still uses the old route. It still delivers, and I haven't changed it. And "delivered" isn't the same as "seen": a mail rule on my own account files these reports in Trash, so I still have to look there.

If Your Site's Email Has Gone Quiet

That's the promise: if something on your site stops working quietly, I'll look for it before you have to ask. I handle that for my own sites and for a lot of client sites.

If you're seeing website emails not arriving, for you or your customers, send me a note and I'll check. If you're technical and want the details of what we changed, ask. I'll walk you through it.
