YouSendIt, a company that lets you send and receive large files through your email, has raised $14 million in a third round of funding.

The financing comes from new investor Emergence Capital Partners (the online services-focused firm best-known for backing Salesforce.com) and existing investors Sigma Partners, Alloy Ventures, Sevin Rosen Funds and Cambrian Ventures. YouSendIt raised a $10 million second round last year.

YouSendIt has a range of offerings, including a free version of its basic service that lets you send files of up to 100 megabytes, as well as plugins For Microsoft Outlook, Adobe Photoshop and more. The Campbell, Calif. startup targets both consumers and corporations, but its niche is small businesses and independent professionals who need to send large files. YouSendIt says it already has 7 million users, and is growing by 200,000 per month.

Competitors include Pando, which is more consumer-focused and, unlike YouSendIt, uses peer-to-peer technology.
