Impressionwise Email Verification and Spam Trap Removal

Threat Intelligence Center


Threat Keys

Protect against high-risk traffic sources. Our digital forensics analytics is designed to identify complex, non-human, machine-generated email accounts that historically use a variety of tactics to generate massive amounts of non-converting impressions.

Methodology Reference


Threat key or string. System-generated email addresses that are randomly generated phrases or words, aiming to make each look different and fool automated email filters. Additional detection techniques are applied in filtering of offensive words, phrases and non-natural email addresses like 1e49cs1pb6@company.com.

Non-memorable machine language-based recipient example:

hus5i3bdgd@gmail.com
bfd7edjfj@aol.com
fgfu998k@yahoo.com
fhf08kr6@b2b.com

Complex, non-human, pattern fingerprint example:

x12345@abc.com
5x1234@abc.com
45x123@abc.com
345x12@xyz.com

Suspicious, multi-platform recipient pool example:

j0nis1funy43@gmail.com
j0nis1funy43@aol.com
j0nis1funy43@yahoo.com
j0nis1funy43@b2b.com

Our data scientists take great care in the development and testing our machine learning technology to avoid false positives while clearly identifying all varieties of non-human traffic sources.
