I don’t think so.
But my Adwords reports are being marked as spam. They stopped to come some time ago and I thought it was a Google fault. Yesterday, I disable the spam filter and they did arrived marked with “SPAM”.
I have 4 adwords reports and just 1 arrives fine, 3 of them are marked as spam.

Why !?

P.S. May 10th, was the last date the four reports arrived.

Provide us the headers of couple of such emails in a ticket in 24 hours of their receipt. We will train dspam. You can also whitelist known sender emails/domains as a better practice.
