Mostly because I have multiple email addresses. But I make good use of the filters (which could be improved) and tags. That really helps with searching through everything.
If I only had one email account I probably wouldn't care as much but that's not as common these days
- Search is atrocious
- I can't find emails from this week but it'll dig up stuff from 5 years ago
- no tagging
- no filtering (tbf, this could be a lot better in most platforms)
- Mail automatically renders PDFs (helps spammers)
- doesn't play well with aliased emails
And a bunch of other things. All minor but they add up
Juggling multiple e-mail accounts in a single client, and I haven't found anything better - also haven't really had any major complaints, the desktoo app works perfectly for what I use it for.
Yes it's very common on sites, and even somewhat forced to have these digital passkeys. It's almost automatic setup and there's a lot of skepticism about them.
