Indeed, at my workplace we use Gmail and it's been a lifesaver for sorting email. Now of course it would not be necessary if only Google implemented sieve or at least proper header and substring search in the backend filters; but some functionality such as tagging and untagging entire threads is very useful. I also use Apps Script at home to send me email if the home network goes offline (a script at home updates a cell in a worksheet every 10 minutes, one on the cloud checks that it's been updated recently). It has saved my frozen goods at least once.
