A simple Email-Sender that uses the smtplib module with the addition of a graphical interface created with the tkinter module

For correct operation, you need to enter your email and password of an (existing) gmail account, after using the "register" button an "account" will be registered in the form of file.txt in the path you want, (the saving method is imperfect but having no knowledge of databases is a simple alternative) after registering, log in using the appropriate button.

ATTENTION the path where the account was saved must be the same when logging in) advice: use the same path for all accounts, once logged in, enter the recipient's email (@ gmail.com).

Your gmail must be authorized for use by third party programs.
