The answer to your question is yes: you can use the mentioned software with Juno because the website provides other features and ways to access your email beside online version and as far as I know, the software does exactly what I said: it uses pop3/imap technology to retrieve emails from your account based on the credentials you have upon registering on the website.
Configuring an email account on the software is easy because it has features like automated wizard which will help you set-up your account in a few easy steps.
Here, I will provide you with the servers from Juno in case you need them :
Incoming mail server (POP3):pop.juno.com
Outgoing mail server (SMTP): authsmtp.juno.com
Please be aware that reading email through these servers requires a paid account.
