What is the Spamhaus policy regarding E-pending (Email-appending)?

Email appending, e-pending, or “enriching” is the supplementation of existing email databases by cross-referencing them with information from other databases. The presumed goal is to add email addresses for customers or prospects for whom the sender has other information.

M3AAWG has published a very clear statement about e-pending: The practice of email appending is in direct violation of core M3AAWG values.

The Spamhaus Project is fully aligned with M3AAWG’s position; we never have and never will support e-pending. Both e-pending services and marketers using e-pending to enlarge their audience risk being listed by Spamhaus.
