firstly it's sending emails and it's work properly but the problem is with 'Body'. It's doesn't take values from inputs.
The sended message look like this:

Name:
Email:
Message:

Example from html:

<input type="text" id="name" placeholder="First Name"><br>

And js:

const nameInput = document.querySelector('#name');
const emailInput = document.querySelector('#email');
const messageInput = document.querySelector('#message');

       // Send email
    const sendEmail = () => {
        Email.send({
            Host: "smtp.gmail.com",
            Username: "email@gmail.com",
            Password: "email",
            To: 'email2@gmail.com',
            From: 'email@gmail.com',
            Subject: "New email from website",
            Body: "Name: " + nameInput.value + "<br>Email: " + emailInput.value + " <br>Message: " + messageInput.value
        }).then(
            message => alert(message)
        );
    }

What im doing wrong?
