Sanebox

Business Insider calls Sanebox "by far, the easiest way to fix email overload". It's simple to set up and will streamline your inbox in a jiffy, letting you focus on what's important without missing a thing.

The principle is pretty simple. The app automatically moves all your "unimportant" email to a folder called "SaneLater". You can check it at any time, and you'll even receive a daily digest summarizing what is in the folder.

This allows you to focus on what's important, and deal with inbox clutter and spam when you have more time.

Make email even simpler, use SavvyDox to handle your document collaboration. Documents are pushed to the reviewer's desktops, avoid the hundreds of emails in an Inbox, and ensure that reviewers always have the current copy of all documents they have been sent available within 3 mouse clicks. No more version control problems because someone grabbed an out of date email from their Inbox!

Sanebox works anywhere you check your email, on any email client on any device. You can try it out for free for 2 weeks. After that, monthly packages start at $7 and go up from there based on how many additional features you want to add.
