YouMail enhances cloud-based telecoms. That doesn’t sound like the sexiest application, but it can do some surprising things with calls and voicemail and well, 17.5 people used it last month, that’s pretty impressive.

The company started developing mobile communication applications in 2009, and has now evolved into a cloud and mobile management platform, with apps available on every major mobile OS.

So what does that do? A number of things can be configured to make calling a bit more personal. Smart voicemail greetings that use the caller’s name, voicemail receipts can be set up with a copy of the message that was left, voicemail messages can also be seen or played through Twitter, Facebook, email or by text message.

If you’re prone to putting your phone aside while working or elsewhere, it’s an interesting proposition to have your messages delivered in this way.

The service also provides ways for users to get a clearer ID for who is calling and ditch telemarketers and sales calls, basically the kinds of calls all of us would rather not recieve.

YouMail is a US only service at the moment and it seems that our American cousins are very comfortable with auto-responding messages and email receipts. Users there can access YouMail on BlackBerry, Android, iPhone, WebOS, Windows Phone 7 and Windows 6.5 platforms.

The company is based in Irvine, California and is backed by VantagePoint Capital Partners, the Tech Coast Angels, the Tech Coast Angels ACE Fund, Siemer Ventures, and CrunchFund. All of which will no doubt be delighted with the latest user numbers.
