AtData (formerly TowerData) is a solid email intelligence platform — strong on validation, deliverability, hygiene, and behavioral activity signals. If your primary concern is email list quality and synthetic account detection from behavioral patterns, AtData delivers.
But it has a gap that matters enormously in fraud prevention: it cannot tell you if an email is actively under attack right now.
myNetWatchman Email Reputation is purpose-built for that question. Our proprietary network continuously harvests live telemetry from criminal infrastructure — the proxies, botnets, and fraud tools attackers use daily. When a fraudster begins using an email address in an attack, we know within 45 seconds.
The right answer is often both: AtData for email hygiene at scale; myNetWatchman for live compromise intelligence at the moment that matters — account creation, login, password reset, and high-value transactions.
Where the gap is largest
Active Compromise Detection
AtData excels at email hygiene and validation — but it cannot tell you if an email address is actively under attack right now. myNetWatchman fills exactly that gap with 45-second signal refresh from live criminal infrastructure.
Tumbled Email Detection
AtData catches disposable domains and standard aliases. myNetWatchman detects tumbled and swapped email patterns — bulk address variations that route to different mailboxes — a technique AtData doesn't cover.
Bad-Actor-Only Signals
AtData's signals incorporate broad behavioral data — including legitimate users — driving higher false positive rates. myNetWatchman signals come exclusively from criminal infrastructure, meaning near-zero false positives on ATO.
We were already using an email hygiene vendor. What we were missing was the answer to the question no one else could give us: is this email being actively used in fraud against us right now?
