I tend to agree with these mail providers.
Emoji have no place is security relevant contexts because their
rendering is far from standardized and unless magnified, they can be
hard to recognize. Also, users have no good idea whether related shapes
might exist or not, so any deviation would be attributed to non-standard
rendering and most likely accepted.
Finally, many emoji involve sequences that may be displayed by some
fall-back means on devices that do not happen to support them. This
makes emoji similar to complex scripts, but that danger is
underappreciated by many people because emoji have an emotional appeal
and appear accessible because the are cute.
