Answer 1

I suspect that you have not registered a "from" email address. You will get a forbidden response when you try to send the email in their example, because the form address is not registered to their account. Assuming you've created a free account, log in and go to https://app.sendgrid.com/settings/sender_auth . In the middle of the page you'll see "Verify Single Sender". If you are just exploring things you can use your own email for this.
