FML.
Does anyone have a good tool to extract emails from Google Apps? I literally only use Apps for custom domain email and a placeholder static website. It's certainly not worth $72 a year for it.
I saw that someone had posted that iCloud supports custom email domains so I suppose that's an option but now need to figure a way to migrate from Google to iCloud.
Found this: https://support.apple.com/en-us/HT212514
One can host 5 domains with 3 email addresses per domain on iCloud.
Imapsync maybe? I haven't personally used it, though I did previously buy it thinking it would download to local machine -- it transfers between accounts using IMAP which wasn't my intent but sounds like it is yours.
I realized that I was just reading about GMail backups a few days. Here are some repos that I happened to star on GH.
