How to share email in zoho mail using python?

I want to share emails and email threads in zoho mail using python. Below is what I have tried so far but it apparently sends an email instead, which is not the purpose.

import smtplib
from notif.notificator import EmailNotificator

server = smtplib.SMTP('smtp.zoho.com', 587)
notif = EmailNotificator('abc@zohomail.com', '******',
                               'xyz.test@zohomail.com', server)
notif.send_notification('Testing')

Can anyone please shed some light on this issue?

Thanks.
