I preserve all my email in archive, which gives me very noisy results when I search the backlog.
So I’ve set up filters in Gmail to automatically tag news and mailing list emails over 5 days old.
I go to Gmail’s web page, select all email with that label, tell Gmail “yes, I want to select ALL emails with that label”, and delete all. Then I go to my email client (MailMate) and re-synch with mail server. Then repeat this for three different Gmail accounts.
After this process, I get much leaner results when searching mail. I try to repeat it every couple weeks. But it’s a pain. How much of it can I automate?
I don’t think this is possible to do via my client, MailMate…
