Hitting a single spam trap can blacklist your entire sending domain. BounceZero detects all three types of spam traps — pristine honeypots, recycled traps, and typo traps — before you send.
Backed by & listed on
Each type enters your list differently and carries different severity. BounceZero detects all three.
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
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
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
The consequences unfold over days and weeks. Catching spam traps before sending is far easier than recovering from the damage.
The blacklist operator logs the send. Your IP and domain are now on their radar.
If you continue sending (e.g., via a campaign), more traps are hit. The pattern is confirmed.
Your IP or domain appears on a DNS-based blacklist. Major ISPs begin filtering or blocking your email.
Open rates drop 40-70%. Legitimate recipients stop seeing your emails. Revenue impact begins.
You submit delisting requests, prove improved hygiene, and slowly rebuild reputation. Some ISPs require waiting periods.
Block 800+ throwaway email providers at sign-up with real-time detection.
