With the proliferation of many new forms of social media and electronic communication, it’s getting increasingly difficult to manage all the inboxes.

There’s no shortage of companies offering to help. Start-ups such as Xobni Corp. organize email. Other services like Threadsy and Gist combine social media streams with email messages. Salesforce.com Inc. and others handle this from a customer relationship management perspective.   

A new start-up, Etacts Inc., is attempting to unify all these messages into one place, focusing on people who have to stay in touch with contacts for their jobs.

“We’re focused on the highly monetizable millions of people -business development people, recruiters, real estate agents – anyone who needs to keep track of their relationships,” said Howie Liu, co-founder of Etacts.

Etacts, which completed the Y Combinator incubator program in March, has just closed a $700,000 seed round from prominent angels including Ron Conway’s SV Angel; Eric Hahn, former chief technology officer at Netscape; Joshua Schachter, founder of Delicious; Jim Young, co-founder of HotOrNot; Barney Pell and Lorenzo Thione, co-founders of Powerset; Jawed Karim, co-founder of Youtube; Ashton Kutcher, actor and now angel investor; Robby Walker and Wayne Crosby, former Y Combinator participants; and Irene Pedrazza, founder of CheetahMail.
