This is a free service that I built in a couple hours, so I put in some limits for now. I didn't want someone to put in a word like 'react' and then get flooded with unwanted emails ('react' is a common English word, most of the results wouldn't even be relevant). I think I'll raise the limits eventually, but I want to add a few more features first, such as one-click-unsubscribe, before I start allowing people to get 1000 alerts a day. In the meantime, feel free to add more specific phrases. For example, you could add 'react js' or 'with react' or 'in react' to get some relevant results.
