I am not responsible if you break any rules while using it though everything was taken into consideration while writing the code.
Update - I have added HTML templates for the emails and made a new script called 'email-script-2.py' use that if you want to send mails in the HTML format Also update the templates with your group links and always try on a demo dataset first. Everything else is same as the first script
You can search "inset-group-link-here" and replace it with your group link in the all 5 html templates. (search without quotes duh )
First download the progress report (csv file) sent to you then rename it progress.csv
open the email-script.py and enter your email ID and password in the main function or generate the app password and use that as password if you have two step verification enabled.
the total worker is 10. you can increase the workers. its totally upto you
Also try on a demo dataset first.
