Another company that have taken the heat for filtered mail is SiteSell. They're blamed for not delivering as promissed, because their e-mail was filtered out. And they hit a wall of unresponsiveness when they tried to right this. Or was it that their requests were filtered out?
As they understood how this is hurting their business, and many other businesses around the globe, they decided to take action, and point customers in the right direction when wanted e-mail doesn't make it into their mailboxes. So they created the "Deliver my mail!" initiative, which I fully support.
