I regularly receive promotional emails from Pizza Hut in Israel. I only ever notice them, though, because they cause my phone to buzz and if I look quickly enough I see the message. Within seconds, though, the message is always moved to my "Trash" folder. I don't have any custom filters that send messages to trash (in the "Filters and Blocked Addresses" tab of the settings menu), so I don't think that could be it.
I initially suspected that the all-Hebrew messages were causing the spam filter to filter those messages out, but again, they're in "Trash" not "Spam".
The beginning of this happening may have corresponded with my switching to Google Inbox from classic Gmail, but I'm not sure about this. What could be causing this to happen?
