Ask HN: Best Email Provider for LKML?

So I send the casual patch every now and then to the LKML (I am subscribed to linux-kernel@vger.kernel.org).

I also like to read what others send from time to time.

I've been subscribed since 2013 to the LKML and yesterday my gmail reached 99.9% of use, unfortunately I found that gmail does not let me delete all of the emails in my linux-kernel label all at once.

I had to delete them in batches of 100 (which takes forever), after that I found I could use date ranges, but it was just as slow.

I had about ~680k emails from the linux kernel mailing list that I had to delete.

I was wondering if anyone here knows of a good alternative (another provider) or a better way to manage large amount of emails, I would like to know your suggestions.

LKML is the Linux kernel mailing list and it's very high in traffic.

Thanks in advance.
