I got this message in my inbox. It bypassed the gmail spam filter, as it was somehow sent from the same account as mine!
This is a bit scary. If I marked it as spam, my emails might start getting blocked by everyone who has a gmail account!
The weird thing is that the message was the predictable "July is the time to get that special Bv1gari w4tch," etc. - but it appeared blank in my email client (Apple Mail). It also had no links for me to follow, if I was the kind of person inclined to throw away money to spammers.
