what is the best email service in the world? which email is more handy to use? is there unlimited email storage around the world?which email should I choose?

there are 3 largest email service providers in the US,namely Gmail,Ymail and Outlook mail. I use Gmail most often. but the storage limit of Gmail is only about 15G.Ymail has 1T storage which is almost unlimited to most of our daily use.Outlook mail is officed by Microsoft,it is also a stable email service with advanced support. among the 3 services, I still reckon Gmail is the most handy and powerful one with customizable features supported. Outlook mail is flashy but improves a lot in recent years. I just spend about ten minutes on finding where to change the default font size in it.I finf it is located at right side of the screen. there is a Apps settings . there are office365 and mail in it. click mail ,and then we go to the real setting option of Outlook mailbox. we can set whether and how we forward emails from it, what the default font is and what is the size and so on. it is a pity that there is no auto-capitalization function in the composing mode.

several other excellent email services aroud the world inclueds yandex mail from Russia ,netease mail from China, which both provide free unlimited email storage and 50M attachment support.
