Twilert lets you get the Twitter search alerts directly in your email inbox and not to mention, it is absolutely free! Twitter users can keep track of the latest buzz on twitter-world through this and possibly use this service to find more people in the same niche as you and socialize with them!
Creating an alert is pretty similar to what we have on Google web alerts. Once you signup, just choose how often you would like to receive the alerts and create a twilert. This is particularly helpful for someone like me who would not like to keep refreshing the twitter homepage, but would like to keep track of something which is of our interests.
