Outlook for pretty much everything. I've been using email since it was a thing, and i've tried many others over the years, but i've also always had interaction with exchange servers since version 5.5 (last 15 years maybe?), so I had a reason to stay with Outlook.

As part of being a consultant I need to interact with about 6-7 exchange/o365 e-mail accounts, so Outlook is mandatory anyway.

On Android I use Nine. Sandboxing of exchange accounts was my primary reason for buying it several years back, and it's an excellent e-mail client.

I use gmail both mobile and web (Also in Outlook) for anything signup/newsletter/forum/junkmail related.
