!
! This section contains generic mail tracking rules — broad patterns (e.g. `pix.gif`, `e.gif`) that
! are commonly used by many different email providers and marketing platforms.
! IMPORTANT: add a comment that explains where a pattern comes from (what tracking company is using it).
! Ideally, supply a link to the document that explains how this pattern is used.
!
! To block tracking pixels in some email clients, percent-encoding is required. Therefore, both variants
! must be added - the original and the encoded version.
