How to transfer emails from one Gmail account to another

You didn't mention whether the folders would be imported also. That is SO important :(

After doing this, I now have my previous email address at the start of every folder name when I go to save an email into one of them. It's as if all my folders are a subfolder of my old email address. Is there a way to rectify this so that only each folder name appears? At present, my folders are named (email address/folder name/subfolder (if any)).

I want to move only some of the emails from one gmail to another. How can I do that?

Didn't work for me. Keep getting the an error. Can't find Pop server

Question. After the importation process is done, can I now delete those inbox in the Gmail where I import it from?
