A spam trap is an email address that mailbox providers and blocklist operators use to identify senders with poor list practices. It never signs up for or engages with real mail, so any message it receives signals that a sender is emailing addresses they shouldn't — often because a list was bought, scraped, or left uncleaned.
Types of spam trap
Pristine traps are addresses created only to catch spammers; recycled traps are once-real addresses that providers reactivated after long inactivity. Hitting either damages your sender reputation and can land you on an email blacklist. Mailpro's anti-spam tools and clean-list practices reduce the risk.
How to avoid spam traps
Only mail people who opted in, never buy lists, remove hard bounces, and prune long-inactive contacts with a suppression list. Read the email deliverability guide. Related: deliverability.
