I would like to configure Gmail to behave like a traditional email service where my incoming messages all appear in my inbox by default. I don't want them sorted into "social", "updates", "forums", and "promotions" categories. I don't mind if Gmail wants to discreetly do that in addition, so long as I will definitely see all my messages when I go to my inbox.
Unfortunately I do not seem to be able to achieve that behaviour, and Gmail behaves very inconsistently. I've already disabled categories in the settings:
That has resulted in the removal of category tabs at the top of the page and what appears on the surface to be a unified inbox view. However, I can still see the categories on the left-side menu:
That would be fine, except that I'm observing the following inconsistent behaviour:
- Messages will sometimes appear in my inbox but not a category
- Messages will sometimes appear in a category but not my inbox
- Messages will sometimes appear in my inbox and a category.
Often the above messages will be very similar looking ones from the same sender, making the behaviour seem almost random. When I click on "all mail" it appears that some messages are being tagged with an "inbox" label while others are not:
My Google searches reveal that this is a common problem but not one that I've been able to find any solution for. For example, see here and note how heavily downvoted the answers are which claim that disabling categories in the settings is a solution.
What do I need to do to have a 100% guarantee that I will see all non-spam messages when I click on my inbox in Gmail?
