A somewhat related tangent, has anyone got good desktop email client recommendations? Preferably macOS/Linux.
I have 6ish email accounts I need to monitor, and outside of Outlook (and the various hellish variations of it), I'm yet to find a good client like all smartphones seem to have - all inboxes in one client presented together. I recall having a number of issues with Thunderbird a few years ago when I last tried it, but I don't remember why.
I use a mix of Evolution[0] (GNOME's Thunderbird) and Geary[1].
Geary has a very nice UI, and can become mobile-like, and Evolution has much more support for automations and other niceities.
There's also alps[2], if you want a web based solution. I love it as well, though Geary is my most used solution.
I'm not sure what your issues were, but Thunderbird is still the king of desktop email clients. It supports a unified inbox, go to the inbox and tick View -> Folders -> Unified
