Goodmail Systems, a Mountain View company that helps people and companies deliver trusted email said it has raised $12 million in venture funding in a round led by new investor SoftBank Capital.

Richard Gingras, chairman and CEO of Goodmail Systems, told VentureBeat about the funding Friday evening, but the news was first released Tuesday. See announcement details here.

There are a lot of email services in the market, and it is unclear how much traction the company has gotten. It had already raised $8 million in a round last year.

Previous investors DCM and Emergence Capital Partners also participated in the latest round.

Goodmail’s “CertifiedEmail” product delivers email with a blue-ribbon envelope icon as a means of signaling the email is legitimate and safe for recipients. Goodmail’s also gurantees mail will be delivered. [Update: According to VentureWire, it charges one-quarter of a cent per email, and charges much less (one-twenty fifth of a cent) for non-profits.]
