A spamtrap (or honeypot) is an email address that was never owned by a real person. Blocklist operators plant them on websites and old lists specifically to catch senders who scrape addresses or don't clean their data. Emailing one can instantly damage your sender reputation.
The honest truth
A pristine spamtrap is designed to be indistinguishable from a real address — no tool can detect every one with certainty. What SalesFury does is flag the high-risk patterns that frequently indicate a trap or an address you shouldn't be emailing.
What the validator looks for
- Known spamtrap domains — e.g. spamtrap.net, spamcop.net and similar. Flagged as high risk.
- Honeypot tokens in the local part — words like
spamtrap,honeypot,trap,blackhole,devnull. - Operations mailboxes —
abuse@,postmaster@,spam@. These are role addresses monitored by IT/abuse teams — never marketing targets. - Scraper-bait patterns — long random-looking local parts (e.g. 20+ character hex strings) that are typical of machine-generated trap addresses. Flagged as medium risk.
How results appear
Flagged addresses show a 🍯 Spamtrap badge in the Email Validator, are counted in the summary, and appear in the CSV export under the Honeypot and SpamtrapRisk columns. High-risk addresses are marked invalid with the reason: "⚠️ Likely spamtrap/honeypot — do NOT email."
What to do
- Never email anything flagged high risk. Remove it from your list.
- Review medium-risk addresses manually — confirm the contact is a real person you have permission to contact.
- Avoid buying or scraping lists. The best spamtrap defense is only emailing people who opted in.
