Email quickly becomes overwhelming when you have lots of messages prying away your fickle attention span. Glider helps alleviate the issue by automatically pulling notifications and commercial emails out of your inbox and into specific labels.
All you have to do is enable the service, spend a minute training it, and wait for the sorting to begin. Afterwards, everything you don't need to see right now will live in a less intrusive corner of your Gmail account.
Glider filters out a lot of notifications and newsletters I'm constantly archiving manually. Sometimes I want to read them, but most of the time I don't care. Now that those messages are in a filter of their own without any effort on my part, I can stop wasting time and take a look at the less important stuff when I have a free moment.
Glider offers a free trial for 14 days, after which you can pay $US9 per month or $US99 per year to continue using the service. Currently, you need a Gmail account and Google Chrome, but hopefully Glider will support more browsers an email services in the future.
