💡 How it works
We create a real temporary inbox — no sign-up, no password, totally free.
Send any email from your normal email client using the account you send campaigns from.
Click Check My Score — we analyse SPF, DKIM, DMARC, SpamAssassin score, and blacklists.
If you see "No email received yet" — wait 15–30 seconds and try again.
Address expires after ~60 minutes. Hit ↺ for a fresh one.
✉️ Subject Line Spam Checker
Paste any email subject line — we'll score it for spam risk, flag trigger words, and suggest better alternatives.
Analyze Email Headers
Paste the raw headers from any email you've sent — we'll decode authentication results, your sending IP, spam score, and the full delivery path.
How to get headers: In Gmail → open email → three dots → "Show original" → copy everything above the first blank line.
In Outlook → open email → File → Properties → copy the "Internet headers" box.
