I just logged-in to my Gmail and I saw following message:
You’re out of storage space and will soon be unable to send or receive emails until you free up space or purchase additional storage.
After quick reviewing of my Drive storage, a large portion went to Gmail and Google Photos. I started using Gmail back in 2004 and needless to say I have millions of emails and it's not easy to clean it up.
What's the most efficient way to do clean up my Gmail? (It's not like I can sort by size and see which emails are taking most of space.)
* UPDATE *
after using certain label, such as this:
label:freebsd-questions -label:starred
I hit Delete
and a minute later I saw this:
Oops… the system encountered a problem (#793) - Retrying in 1s…
and when I opened another tab to Gmail I saw this:
Gmail by Google
Temporary Error (500)
