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)
my_group.notify(group_users, subject, email_body, 'email')‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Shame this went unanswered....came here looking for this very thing. Years later and I can't find helpful resources.

The 'message' argument doesn't recognize python delimiters but it will recognize html formatting.  In my usage I've been able to add bold, paragraph, break, style, and link HTML tags to my email body and they come through in the resulting email.
