Today a new service called Topicr launches. It’s meant to address email users’ inability to send and receive numerous and large attachments and manage the transfer of visual and audible media within the classic compose-subject-body template. If you’re into sharing media by way of email, you might find it hugely useful.

Email has been the primary communications method for Web users for decades, and for good reason. It’s simple and effective for both short- and long-form correspondence, relatively easy to catalogue and search, and works whether your at home, at work, or on the go. (Here’s to look at you, RIM.)

Of course, it is also the bread and butter of the spammer crowd, but that the unfortunate result of the mass popularization of technology.

But despite its obvious strengths and the virtually ubiquitous access to email that Web users currently have, most mainstream services - those from Yahoo, Microsoft, and Google, just to name a few - have failed to capitalize on recent improvements in online communications. While several of the largest email providers continue to limit the depth of storage provided users for good reason, transfers of attachments continue to be limited. This has allowed services like Pando and YouSendIt to build businesses based on the idea that people should be given the opportunity if need be to send large files to one another over the Web quickly and easily.

Of course, why they’ve come to be laggards is rather simple. They have amassed hundreds of millions of users (divvied up among the top 3 or 4 webmail providers on the Net), and thus they’ve grown fat and happy, and have seen little incentive in bringing significant change to the historic medium. And though that conclusion is certainly cause for frustration, we at Mashable imagine that it’s not an entirely terrible reality. Just as long as we’ve got options to the contrary.

Topicr is utility that serves precisely that role. While we’d enjoy much more if Topicr were to find a cosy home as some kind of extension placed conveniently within our chosen email services, always ready and waiting, it presently stands more or less a solitary device.

But because it masquerades any messages created within its toolbox as if they were delivered by your preferred email service, your friends, family and colleagues can respond to you as they would with any other message sent their way. Plus, if your contacts happen to find themselves persuaded to join the Topicr membership after they’ve been intrigued by your media-rich messages, they can extend their responses with easy-access attachments (i.e., pictures, videos, songs) as well.

The product of these communiques can quickly become far more rich in presentation than they otherwise would be - and all without much time spent creating them.

Furthermore, the options for placing media within email through Topicr aren’t limited just to sending photos or videos or music. Users can sent combinations of image slide shows and music for synchronous playback. Doing so could save users a good deal of time if they’re ordinarily accustomed to producing such displays via a local software program of some sort.

Without going into too much detail here, it’s easy to see that Topicr presents itself as a potentially useful addition to your email communications. We’ve only lightly touched on the list of options available, and, well, you can imagine that this could make for a fairly powerful platform if exploited to great extent by users.

If you’re feeling adventurous, and wish to take Topicr for a spin, the company has made available 1,000 invites available to Mashable readers. If you’re quick enough to click this link, you’re in.
