MailChannels is a privately held, anti-spam technology company based in Vancouver, British Columbia.


MailChannels provides a software for outbound Spam filtering that assists businesses by preventing spam from leaving the network. The software can be operated as a mail relay or transparently to filter spam coming out of servers not administered by the Web hosting provider.

MailChannels offers a cloud-based SMTP relay service that filters and sends mail on behalf of businesses to ensure email deliverability.

MailChannels' clients include web hosting companies and Internet service providers such as Bluehost, UK2 Group, FortressITX, SendGrid, Sherweb, Globe Telecom, Ezecom, and Walla!.

Company History[edit]

The company was founded in 2005 by former engineers of ActiveState (acquired by Sophos) who created one of the first commercial spam filters.

The company's first product was an SMTP proxy that provides tar-pitting and transparent SMTP proxy functionality for inbound email filtering. At the 2007 MIT Spam Conference,[1] the company's founder, Ken Simpson, was awarded the "best paper" award.

In 2007, MailChannels joined MAAWG.

In 2010, the company launched an outbound email filtering platform that claims to be capable of filtering up to 30 millions messages per hour, transparently in the network. Outbound mail filtering involves scanning email traffic as it exits the network, identifying compromised accounts, and reducing the risk of having IP addresses blocked by receiving networks.
