Answer 1

Easiest option:
ajax + php + PHPMailer (or at least the built-in php mail function )

Answer 2

Scheme of actions:
1. Raise a simple back (what is more convenient for you php, nodejs, python, ruby, etc.);
2. Choose either a mailing service and use it, or find a library that can work with a mailbox and drop messages from it, and connect to it;
3. Create a simple API, if you only need to send mail, then with 1 endpoint;
4. Accept the request on the server, take the data, and send it to the mail, the documentation for your library or service that you have chosen will tell you exactly how to send it

Answer 3

Fast, clumsy and head-on...
Send emails with js...
