What I find interesting is that I spent a good few evening clearing out the junk from my gmail account. I got it down to around 80% and within a few weeks I'm back to 95% again...
Could you possibly be getting 2.25GB of email in a few weeks? I mean, email is pretty small, at least unless it has attachments.
I wonder what's going on. It seems unlikely to me it's really 2.25GB of spam email in a few weeks.
Gmail has a pretty good interface to creating automatic filters to tag,move,or delete crap built in or if you prefer imapfilter lets you basically write a lua program to filter your email.
I guess that's what filters are for but I'm pretty lazy in that regard too.
All those emails are required by law to include an easy unsubscribe link in the email, usually it's at the very bottom in a small font.
When it is not clear, or there isn't a good place to put it, stuff starts to pile up.
Once I have figured out where it should go, which is 99.99% of the effort, actually getting it there usually isn't that big a deal. You can organize 500 emails in an hour if you have set the systems and the shortcuts up - less if you can do it with filters.
When you say "so much junk", are you talking about spam that Gmail isn't catching? Or just legitimate mail you don't find very interesting?
