I use google take out to do a dump of email and back up the download file. In order to clear out a bunch of space on my gmail account, I did a full export and then deleted conversations based on date. I ended up having to use a script which ran over a few days, due to limits on how fast I could access messages. This was all to avoid signing up for a paid account.
