Thanks for the info y'all. You are correct the emails come from an itch.io email address but are clearly from the creators. Seems maybe dropping all permissions for email will stop them. That said, I was hoping for a way to opt out of creator emails WITHOUT having to unsub every single email from Itch.io. I don't mind getting some updates from the platform. Sounds like there might not be a way to stop the creator emails without stopping all itch emails then?
Viewing post in Mass opt out of creator email?
Judging only by the settings I see this option:
[ ] New devlogs and updates from projects I follow
I suspect that a creator sending e-mails to all their users counts as “updates from projects”, so maybe this might work?
Unfortunately I haven’t experimented a lot with these, maybe someone else can give a more accurate response.
