What are typotraps or honeytraps?

Typotraps (also called typosquatting traps) use misspelled versions of common domain names. Addresses like user@gmial.com or user@yaho.com catch senders whose lists contain typos that were never corrected through confirmation processes.

Honeytraps are addresses deliberately seeded across the internet to catch scrapers and list purchasers. They appear on websites, forums, and other public locations where scrapers harvest addresses. Sending to them proves you obtained addresses through scraping or purchased data.

Both types indicate list hygiene failures. Typotraps suggest you are not using confirmed opt-in (which would catch the typo). Honeytraps suggest you are acquiring addresses through illegitimate means.

The solution is the same: only send to addresses obtained through confirmed opt-in where the recipient actively verified their address.

Typotraps catch carelessness. Honeytraps catch deliberate misconduct. Neither belongs on a legitimately built list.
