Some (a small minority of) mail servers will bounce back emails regarded as
spam; most will simply silently delete spam emails or route them into the
user's spam folder. So no, the bounce mechanism doesn't report spam details.

If you're concerned about your emails being marked as spam, consider
utilizing the SendGrid-Google App Engine integration and sending your
emails from SendGrid servers. You'll have better access to analytics; see
an explanation here:

[google-appengine] Email feedback loop notifications when emails are marked as spam

[Waleed Abdulla]

The top email APIs (like Sendgrid and Amazon SES) notify applications when
an email bounces or is marked as spam. They know when an email is marked as
spam through email feedback loop agreements with major email client
providers.

App Engine notifies
applicationswhen
an email bounces back. But is there a way to know if an email was
marked as spam? Do those bounce notifications cover spam reports as well?
The documentation does not include a lot of details about the type of
notifications we get (soft bounces, hard bounces, spam reports, ...etc.).

Can anyone shed some light?
