I actually have no idea, I just know that on my SendGrid dashboard there is a graph for what percentage are being marked as spam. I agree that it's a bit fishy as I have never seen it as anything other than 0% - my research group has many projects that are sending a lot of emails, so I'd expect at least one or two of those emails to hit a spam folder somewhere.
