Format smtp notifications to Group members, arcgis-online

[ZacharyUhlmann]

Hello again.  I want to send a simple e-mail to members from an ArcGIS Online Group.  A general version of the script is provided at the bottom. PLEASE help me if you know how to format the email_body for the (it appears) smtp message.

My main concern is FORMATTING the email_body because the message protocol clearly does not recognize Python string delimeters - the newlines and tabs are not being produced, just one long sentence basically.

 I have found really helpful resources for more heavy-duty automated messaging (for instance: Send Email When a Feature is Added to an ArcGIS Online Hosted Feature Service )  BUT it does not appear I can access e-mails of Group members, so I am confined to the Arcgis Python API using the Group.notify method.

from arcgis.gis import GIS
from arcgis.gis import Group

# get gis object
my_gis = GIS(username = <my_username>, password = <my_password>)

# Group User Info: dict with keys - owner, admins, users
my_group = Group(my_gis, <group_id_number>)
members_dict = my_group.get_members()
# give me list of user names from group
group_users = members_dict['users']
subject = 'Changes and updates to group'
signature = 'Zach <Lastname\>nGIS Specialist\n(123) 456-7890\tmyemail.com'
email_body = '''Hi everybody,\n\nWe have changed some content and protocol
                updated and added metadata to the existing datasets -
                feature layers and shapefiles - and did other stuff.
                \n\nFeel free to contact me if you have questions.
                \n\n'''.format(signature)
