* Email notifications sent after performing an action:
    * As connecting to an email server and sending an email tends to be "slow" (several seconds), you can return the response right away and send the email notification in the background.
* Processing data:

            return false;
        }
        return details != null ? details.equals(that.details) : that.details == null;
    }

        result = 31 * result + (details != null ? details.hashCode() : 0);
        return result;
