Your inbox is worth much more than your money, if they can take both they will. They are already charging for additional storage, so I expect it will just continue on that path.
Online sellers email me that order #2748747284933938 has had its status updated. Click link and yippee, it’s gone from order received to processing. That’s the email. Thanks.
It’s really annoying and turns me off using those products.
My personal email is almost entirely read-only, and nearly all its utility is letting computers, not people, send me messages that I'm expecting.
I mean, I click < 1% of these kind of email links but I'm glad I get them on the off chance I do.
For some things, I’ve taken to copying the page of my purchase and replying to myself in the inevitable “thanks for your order” (and zero details of it in the email).
God help you if you have multiple people (spouse, kids) using your Amazon or whatever account.
If you are in the habit of exchanging a large amount of documents and pictures over email, a dedicated storage solution might be more appropriate.
Work-related communication, as in freelancing, might deserve a separate mailbox that is kept clean of unimportant things.
I could go on and on for what I'd consider a great cleanup experience. It's surprising to me that such a thing doesn't exist, nor is it the kind of thing that's built into Gmail itself. You'd figure they would be best to offer a simple cleanup experience that has sane defaults.
