Cloud email management startup Mimecast — the leading supplier of email management solutions for Microsoft Exchange and Office 365 — has raised $62.15 million in its third round of funding, the company announced today.

Mimecast has attracted more than 6,000 customers worldwide by helping companies better manage email with help from the cloud. It makes Exchange and Office 365 a more unified solution and makes sure emails are always available, secure, and compliant. It claims to have more than 50 percent year-over-year revenue growth in six of the last nine years.

“Today’s businesses are as dependent on email as ever but, increasingly, email struggles to keep up as the way we create, store, and share information changes,” Mimecast CEO and co-founder Peter Bauer said in a statement. “At Mimecast, we believe email needs to be rewired if it is to continue to deliver real value to businesses. Building on our history of innovation, we are working to make email more collaborative and more interactive to realize the true value of the vast amount of unstructured data in email stores.”

The new round of funding was led by Insight Venture Partners with participation from existing investor Dawn Capital. Including the new round, Mimecast has raised $83 million.

“Email is the most important means of business communication and, better than anyone else, Mimecast delivers a true integrated solution for secure and accessible email,” Jeff Lieberman, Managing Director at Insight Venture Partners, said in a statement.

United Kingdom-based Mimecast was founded in 2003. It has offices in Europe, North America, Africa, and the Channel Islands.
