How makers stay productive

I have 11 different email addresses being routed to various inboxes/filters in Gmail - each inbox has a general subject, and corresponds to an email that I use to sign up for newsletters in that category. But I suppose I'd like a way to more intelligently search them, or more to the point, automatically search them. I've played with gmail filters, but couldn't really achieve what I wanted to. Say you had a bunch of e-commerce/shopping emails coming in…I wish I could automatically have an inbox search/collect emails that say, include info about a sale above 30%, or jeans under $40. Maybe this is possible with filters, but then you would have to have many, many inboxes. And to search for all that you want over and over would be too time consuming. I basically wish I had a UI that could better support many categories/queries…sort of like how you can create different views for Airtable. Something like that! 😆

What do you mean by aggregating emails for keywords? A search function? I'm asking because while kanbanmail.app is still in early stages, I want to build it out into a full-on email smashing platform eventually!
