When dealing with managers, this may show you as being organized, proactive, and on the ball. Instead of expecting them to respond to the email, you take the burden away and also appear more responsive. When dealing with clients, this will wow them. The advantage you have in these situations is that, for the next few minutes after the read receipt, you know you can call or otherwise drop in on your client or manager and know that you're not interrupting them or taking their thought away from something else. It can be a tool to know that your manager is actively thinking about a problem you're having that you specifically need their help with.
