Spam Trap Checker: test an address before you send to it
Built by the SpamCipher Engineering Team·
Enter an email address to score its spam-trap risk. A trap is an address that accepts mail and reports the sender, so one in a list can undo months of reputation work. This scores the signals that separate a trap from an ordinary address: whether the domain is disposable, how old it is, whether it already sits on a blocklist, and whether the local part looks recycled or mistyped. If the answer is risky, run the domain through Blacklist Checker to see whether the damage has already started.

Frequently Asked Questions
What is a spam trap?
An address that exists only to catch senders who are not managing their lists. It accepts mail and reports the sender to blocklist operators. Nobody ever signs up with one on purpose, which is why they are a reliable signal of a list that was bought, scraped, or left unclean for years.
What are the different kinds?
A pristine trap was never a real mailbox and only ever catches scraped lists. A recycled trap was somebody real years ago and was reclaimed after long abandonment, so it catches senders who never remove people who stopped opening. A typo trap is a misspelling of a common domain, and it catches forms with no validation on them.
Can any tool tell me for certain?
No, and treat anything claiming otherwise with suspicion. Trap lists are deliberately secret, because a published one stops working the day it is published. What this does is score the signals that correlate with traps, so you can decide what to do about a risky address rather than find out from a blocklist.
What should I do with a high score?
Do not send to it, and look at where it came from. One risky address is a bad address; a batch of them from one import is a source you should stop using. Removing the address does not undo a hit that already landed, so the value here is before the send rather than after.
