GMail

I have two email apps for gmail, one which seems to be an old one, and a newer one which has the same emails, but divides them into primary, updates, social, promotions, and something else ( maybe the columns Annie is meaning?) I don’t look at that one much, as I prefer to see them in the old format.
My problem is that a person in America is giving my address, so I have now built up a profile of her purchases etc!
My email address is just my name @gmail.com, so I am loath to change it. America lady is using the same name, but with a dot in the middle, so gmail doesn’t recognise the dot apparently and I get receipts etc.
I also get some for an Irish lady whose name is a tiny ( unusual) variation of mine. I always reply to these ones, and nearly always get a thank you.

Hi Anniel, I'm using a Chromebox so my Gmail interface may differ from yours. For an email alternative, I switched from Gmail to ProtonMail personally. As a longtime Gmail user, I find ProtonMail a better fit nowadays. I still need Gmail for work emails, but ProtonMail is my go-to for personal stuff now. Might be worth checking out if you're looking to move on from Gmail.

Interesting replies. If you have standard gmail try not to update it. Many people hate the new version. Thank you Chestnut and Welbeck. I will look at both suggestions.

I have three e-mail addresses with BT Internet and two with GMail but I collect them on my computer through eM Client. You download eM Client and then it's quite easy to add each one. Then when I open eM Client it checks all five e-mail addresses all at the same time and downloads any new mail which I then sort into folders. I think the free version only allows 2 or 3 addresses but I paid for the full version.

I am on gmail and do not like it.

When I want to file/move an email to/from the same person to a folder I have to do each one separately. Cannot work out how to do move them altogether. Any suggestions please?

I was going to ask the same question - 3 columns?

i use chromebook.
not sure what you mean by 3 columns.
i can see gmail ok, but i do select the basic display, which is going to disappear next year.
