Dear Alain Jurado,
Good day! Thank you for posting to Microsoft Community.
As a Microsoft customer support agent, I can only provide you with information on how to use Outlook for email marketing and Microsoft 365 exchange online services only. since your query is out of our Forum scope and as we provide limited knowledge, I cannot provide assistance with creating a back-end for your project using Python and PyCharm related scenarios. However, I can suggest that you may take a look into using Microsoft Power Automate (formerly known as Microsoft Flow) to create automated workflows for your email marketing campaign. Power Automate integrates with Outlook and other Microsoft products, and can help you automate tasks such as sending emails, creating tasks, and updating spreadsheets. You can also use Power Automate to connect to other services and automate tasks across multiple platforms.
Thank you for your precious time and understanding. Have a nice day.
Sincerely,
Libeamlak | Microsoft Community Moderator
