Spam Trap
01 Definition
Spam Trap meaning: An email address used only to catch senders with poor list hygiene.
A spam trap is an email address that mailbox providers or blocklist operators use to identify senders who do not manage their lists well. It never opts in or engages, so any mail it receives suggests scraped or stale addresses. Hitting traps can severely damage reputation or trigger blocklisting.
Why it matters
How Spam Trap fits the work
Spam traps let providers spot senders who buy, scrape, or fail to clean lists, so avoiding them through permission and hygiene protects your sending reputation.
In context
An old purchased list contained a spam trap, and mailing it landed the sender on a blocklist within a single campaign.
Practical note
Pristine traps are addresses never used by a real person, while recycled traps are abandoned addresses reactivated as traps, so regular engagement-based list cleaning reduces both risks.
