module: email
short_description: Send an email
description:
  - This module is useful for sending emails from playbooks.
  - One may wonder why automate sending emails?  In complex environments
    there are from time to time processes that cannot be automated, either
    because you lack the authority to make it so, or because not everyone
    agrees to a common approach.
  - If you cannot automate a specific step, but the step is non-blocking,
    sending out an email to the responsible party to make him perform his
    part of the bargain is an elegant way to put the responsibility in
    someone else's lap.
  - Of course sending out a mail can be equally useful as a way to notify
    one or more people in a team that a specific action has been
    (successfully) taken.
