Internet marketers are panicking right now. I've received a dozen of e-mails to teach me how to bring their "not promotions" e-mails back to my primary inbox...Hate it or love it but I think Microsoft Yahoo Apple are going to follow that trend too... Of course the system is not perfect yet but it is something regular people are going to love...at least my mom love it. I have 5 tabs up and running.I have more control over my inbox now. I can understand why internet marketers are mad because it is a new ball game to be next to Facebook updates versus in a box alone with other promotion e-mails... In the long term your brand your goodwill are your only and best weapons...Open Rates are just one metric because you can have one open and 5 conversions versus 5 opens and 0 conversions... the main difference here could be that one open leads to 10 shares on Facebook....This new UX is a non issue...it is really time to disrupt the e-mail system
