Yep sorry I wasn't specific and thank you for clarifying. Auto forward so like I want my girlfriend to receive all my Walmart+ emails which doesn't let you have accounts like Amazon. So I forward all emails. Had to keep my Gmail to just make it easy. I'm sure there's a more complicated setup but it's Walmart... I just need email to get to both of us about orders.

It's like this because it's secure, there's was good reason they didn't have this feature. But it's inconvenient and I'm not using Proton because I'm a secret agent, I just to want to pay for a product instead of being the product.
