What could be a major setback to Goodmail, Google has decided not accept payment from approved bulk mailers to ensure their emails reach Gmail users' Inbox bypassing any filters.

"Gmail has a superior spam detection system that gives users ultimate control over the messages that are filtered into their spam folders," said Eileen Rodriguez from Google Corporate Communications.

AOL and Yahoo have already signed deals with Goodmail Systems but Google has finally refused to implement an email certification system like Goodmail's Certified Email ending months of speculation.
