I have a lot of experience working with Python mail libraries.
Some example projects of my own:
- a client that reads an Excel datasheet containing names, email addresses and company names, then send a personalized email based on a template, replacing the name and the company
- a gmail client that sends messages with special syntax in object field and in the email body, to be read by another client to trigger actions on the PC
- a gmail client that reads the inbox, looking for special types of emails sent by the client described above, then parses it and then execute the actions described in the email.
The last 2 exemples mentioned above fit tour need in my sense
