Email fraud prevention startup Emailage Corp. has raised $3.8 million in a new round led by Felicis Ventures that included Double M Partners and Mucker Capital.

Emailage helps customers world wide to predict fraud risk before a transaction happens, and promises to be the next logical solution to tracking digital reputations, clearing good transactions, and cutting fraud.

The company works with financial services, airlines, ticketing, Bitcoin, digital rights and e-commerce companies to prevent fraud.

“Email is the most unique and common ID in the online world,” CEO of Emailage Rei Carvalho told SiliconANGLE via email. “By using our proprietary machine learning algorithms across a vast consortium of data, we are able to stop fraudsters in real time. As our customer base grows, our solution becomes more powerful and our industry-leading fraud detection rates will continue to improve. We are excited to use this financing to grow quickly and expand our offerings.”

The company has some impressive stats, saying that over the past year they have almost tripled the number of transactions analyzed, and have flagged over two million transactions as risky. In 2014 alone, Emailage claims to have saved customers an estimated $150 million in fraud.

“We are excited to partner with Rei and the Emailage team. In 2014, over $5 billion was lost to fraud due to account takeovers alone; as online commerce expands, fraud is a top of mind issue for most companies,” Managing Director of Felicis Ventures Aydin Senkut told SiliconANGLE. “Emailage’s API is easy to integrate and does not require the use of sensitive customer data, enabling them to leverage data across customers and create powerful network effects for everyone.”

Emailage raised a seed round from Mucker Capital in January 2014, and a subsequent round of $4 million (which was reported at the time a Series A) from Double M Partners in October 2014. The company claims this new round is Series A, and yet the public record would suggest that it’s Series B; which ever they’ve definitely raised a new round.

Total funding for the company with the new round is around $7.8 million.
