Hello,
similarly to the issue described here https://itch.io/t/1856548/how-do-i-turn-off-email-notifications-for-games-i-have... , I get unsolicited emails from games I bought with various bundles. I did NOT use any script, I added the games that were of interest manually.
Please turn off all such game creators' notifications for my account on your side in bulk. I have changed any available setting in my itch.io profile to suit my needs, it doesn't work for those emails.
Thanks.
