I get all my GMail, three accounts, via O.E.Classic, email program, and NOT via a Browser, where you're forced to use Web-Mail. To me, Webmail really sucks!
The only drawback to using a third party email program like O.E.Classic, is that you need to go to Google and get an App Password for each account. That's a very convoluted process, but once you've done it, it's DONE and you can then use an Aftermarket Email Program. (I found a U-Tube video that shows exactly how to get an App-Password)
O.E.Classic loads when my PC boots up, and then checks my Inbox at Google, every three minutes as long as the program stays on. In my case, it's ON all day, so I never miss an email. Once an email is downloaded by O.E.Classic, it's deleted from the Inbox on Google.
O.E.Classic is like a clone of "Outlook Express" , a program that I used for many years, through earlier versions of Windows.
