It seems like Google are using some kind of correction script now and then, rather than have it fully automated daily etc.

I've had Google flagging GOG emails as dangerous for 4 months now))

Yup just bough 2 games and the confirmination recept email landed in spam, previously it only happened with freebies.

I've seen this a couple of times. But I'm just marking it as not spam. Maybe google will learn later.

I had to flag many GOG mails as NOT fishing and tag them as important in order to stop them to be flagged as spam.
And it seems receipts, freebies and exclusive discounts were all flagged separately

This just happened to me for the first time. It seems very strange.

Happened to me as well. Odd, and somehow it made me remember the 2010 April fools when they said they were shutting down. Hah.

Google is weird, while they have gog commercials for games now which i approve and like on youtube but then their gmail keeps sending the emails of gog bought games to spam.
It's not g2a like they advertised sometime on youtube that scam site. That should have been sent to spam, but i only bought games on gog and steam for now.
