I recently recieved an email from an allegedly reputable source. It said that DAW publishing was seeking new authors , longer books considered. Inner skeptic said "Hmmmm, doesn't track" . It went against all wisdom written since ( and before ) The Bushama Depression. The email said that they accepted agented and unagented manuscripts. Inner skeptic replied " And one size fits all." Even when I was a kid and started my collection of reject notices, the slush piles were reportedly taller than I. And like Dorothy, I wanted to see what was behind the curtain.
DAW is part of Penguin books. They do not accept unsolicited manuscripts. This per their website.
