Twilert is a free Twitter application that lets you receive regular email updates of tweets containing your brand, product, service, well any keyword you like really.
Very cool set-up interface. The designers did a great job. The lack of documentation is a little frustrating, but it seems to be cool. I would add more examples of how to use the tool and maybe canned reports that you can start with. Also, more than 10 queries is going to be important. Also, it would be great to be able to set-up the reports on-demand versus having to say when you want the reports.
This isn't too bad! I think that this will be helpful for me for those search terms that I monitor just for research purposes and not necessarily real-time - I just watch them to learn about the market and so I don't necessary need to monitor them in real-time. Having an email once a day for the notification is just fine and this will keep me disciplined to make sure I'm actually doing that. Plus, hello, free... Pretty decent search results from what I can see as well.
