URL shortening services are as many as the sands, to quote a poet whose name I can’t sadly remember right now. URL Mule is a new contender, and it has a nice range of features that might give it a bit of a fighting chance.
The provided interface lets you not only shorten the address in question but also forward it to your inbox on the spot. In addition to that, you can choose to be notified whenever someone clicks on your link.
Moreover, the links that you create using URL Mule do never expire. That is, they will be up and running for as long as the service is available. Speaking of the links you create, it is interesting to note that the service abides by a “No adult sites allowed” policy, and that will be a good point on many people’s books.
To sum it up, URL Mule will enable you to share links in an easy and supple manner. While there are many related service providers, it is a bit difficult to innovate in a field as specific as this one. Still, I really look forwards to any radical development that might be forthcoming, and update the process or shortening URLs as we know it.
