Email delivery can feel like voodoo—you hit “send,” and hope it lands. Misconfigured servers, blocked ports, bad credentials… everything can fail silently. That’s why I built SMTP-Test.com: a no-code, one-click online tool that helps you troubleshoot email issues in real time.
🔍 What it does
Instantly connects to your SMTP server—be it Gmail, Outlook, AWS SES, SendGrid, Mailgun, or your own.
Shows a live, readable log of the server handshake—like Wireshark but for SMTP.
Optional test email send to confirm delivery.
No account or installation required—just fill in your details and go.
👩💻 Why it's for developers (and non-devs!)
Save time: No digging through logs—see exactly where it fails in seconds.
No technical jargon: The output is translated into human-readable messages.
Great for teams: QA, support, and marketing folks can test SMTP quickly without needing shell access.
💡 How it works
Go to SMTP-Test.com.
Enter your SMTP server info: host, port (25/465/587), security type, credentials.
Click Test Connection.
Watch the log unfold—step-by-step feedback tells you what worked, what didn’t, and why.
Logs show every command (EHLO, AUTH, MAIL FROM, RCPT TO, etc.) and server response in a clean, live view. No noise—just clear diagnostic info.
🤝 Alternatives & Why It Stands Out
Other SMTP testing tools (like SMTPer, Zoho, and DNS Checker) offer similar functionality, but many add noise—extra DNS or blacklist checks you don’t need. They also often hide output in static reports. SMTP-Test.com is:
Fast — everything is live and browser-based
Simple — no sign-ups, no dashboards
Focused — pure SMTP, no fluff
🧪 Real-world example
I once had an SES account that refused connection from my CI pipelines. Ports seemed open, keys were valid, but emails failed silently. SMTP-Test.com uncovered a TLS mismatch in seconds—fixed in <5 minutes, without terminal gymnastics.
🔗 Try it now
Head to SMTP-Test.com → enter your SMTP info → watch it connect. It’s free, lightweight, and will save you hours the next time email just doesn’t arrive.
