For a lot of small business owners, the inbox is where things start to feel slightly out of control. Not in a dramatic way. You're replying to messages, you're keeping things moving, and from the outside everything looks like it is being handled. But there are always a few emails sitting there that you've read and not replied to. A couple you meant to come back to. Something that you're fairly sure you've forgotten, but can't quite pin down. So you check it again. Then again.
