gmailctl VS labeller

Take a look at gmailctl and run the gmailctl init command -- it will give you a step by step set of instructions on how to do what you're looking for. You do not need to do a review when you are accessing your own data only, and you can use "in production" status without needing to refresh every 7 days.

I've used https://github.com/mbrt/gmailctl/ to tame my inbox with some degrees of success, but gmail filters are just so flaky.

Next step in my things-to-try list is to just download the inbox via imap and sort it out locally.

That's pretty cool, thanks for sharing.

I wrote a simple scripting utility to do similar labeling actions, bacause I came to gsuite with a large procmail configuration file previously. It was useful for a while, but gradually I stopped updating the filters:

Nice to see there are other people doing similar things though, I'll definitely take a look at this more carefully over the next few days.
