Spam traps are rare - only about 0.02% of the addresses we verify - but they are the single most damaging address a list can contain: one hit can land your domain on a blocklist for months. Rarity is exactly why guessed and scraped lists carry them undetected.

The 3 Types of Spam Traps

Each type enters your list differently and carries different severity. BounceZero detects all three.

Pristine Traps

Never-legitimate addresses created solely to catch spammers. They have never been used for real communication. Hitting one is definitive evidence of buying lists or harvesting emails.

How they enter your list: purchased email lists, scraped web data, form field scraping.

> Severity: Medium

Recycled Traps

Formerly real email addresses that were abandoned, expired, and later repurposed as spam traps by ISPs and anti-spam organizations. Common in old CRM data and purchased lists.

How they enter your list: old databases, CRM imports with stale data, not removing inactive contacts.

> Severity: Medium

Typo Traps

Misspelled versions of popular domains (gmial.com, yahooo.com, hotmial.com) that catch sign-up form errors. Reveal you're not validating emails at the point of collection.

How they enter your list: unchecked registration forms, imported data without validation.

> Severity: Medium

What Happens When You Hit a Spam Trap

The consequences unfold over days and weeks. Catching spam traps before sending is far easier than recovering from the damage.

Day 1
Trap hit recorded

The blacklist operator logs the send. Your IP and domain are now on their radar.

Day 2-3
Pattern confirmed

If you continue sending (e.g., via a campaign), more traps are hit. The pattern is confirmed.

Day 4-7
Blacklist listing

Your IP or domain appears on a DNS-based blacklist. Major ISPs begin filtering or blocking your email.

Week 2-4
Inbox placement collapses

Open rates drop 40-70%. Legitimate recipients stop seeing your emails. Revenue impact begins.

Month 1-3
Delist process

You submit delisting requests, prove improved hygiene, and slowly rebuild reputation. Some ISPs require waiting periods.
