# A helper class to send an email. It will also handle a nil message, which it considers
|
|
# to be "do nothing". This is because some Mailers will decide not to do work for some
|
|
# reason. For example, emailing a user too frequently. A nil to address is also considered
|
|
# "do nothing"
|
|
#
|
|
# It also adds an HTML part for the plain text body
