Spam traps come in types. Pristine traps are addresses never used by a person, so they should never be on a legitimate list. Recycled traps are abandoned addresses repurposed to catch senders who do not clean their lists.
Why it matters
Hitting a spam trap signals that you may have scraped, bought or neglected your list. It can lead to blocklisting and lasting damage to sender reputation.
Common pitfalls and tips
Avoid buying lists, scraping addresses and mailing very old contacts. Regular verification and removing long-inactive addresses are the best defences against recycled traps.
Example
A company emails an old purchased list. Several addresses turn out to be spam traps, and the sending domain is blocklisted until the team removes the list and rebuilds its reputation.
