Sailthru, a behavioral marketing email service, announced today that it has secured a seed round of $1 million, first reported by Business Insider. Founder and Chief Executive Neil Capel has since confirmed the funding, which will be used to expand its sales operations and new feature development.

Sailthru offers several email tools that can be used by companies to optimize outbound email marketing campaigns as well as manage service providers. The first tool, Triggermail, monitors emails sent to customers and what happens once it reaches their inboxes. The second tool, Horizon, tracks customers browsing habits on their websites and helps to format and send customized newsletters based on the information collected. Lastly, GetConnect aggregates email services so that users can send email from one tool, rather than sending via a bunch of different tools separately.

The company claims it doesn’t have any direct competition, though there are others that do enable and track outbound email marketing such as Constant Contact and Exact Target. But Sailthru appears to be the only one optimizing company newsletters based on browsing habits.

The New York City-based company, founded in 2008, is working with a variety of companies, including Business Insider, Tumblr,, OMGPOP, and

Funding was led by DFJ Gotham and included Metamorphic, RRE, Pilot Group, Thrive and Lerer Media.
