Interesting, I've been getting very similar spam messages slip into my gmail inbox.

Likewise.

Same. After years of almost zero spam, recently I've been getting stuff like that about once a week in my primary inbox. Very annoying when my phone dings only to show me obvious spam.

I have the same problem, before these emails would go into the SPAM folder but now even some obvious 'YOU HAVE WON THE LOTTERY !" emails are arriving into the inbox directly.

Have you checked the mail raw text. Maybe it's just disguised as gmail but sent from another third party server. Or spammers found a way to spam within gmail or hacked gmail. Both had happened at least once.
