I was a missinglettr user since the beginning and loved it, watched it grow and develop and even sent them a few customers. Then help shelf and then the events platform and i thought that must be it. One thing i was missing was promotion of content socially and with a viral feel to it. Then appsumo brings in quuu promote and I was like "Hell Yeh!." Used the codes and then realized it was seriously expensive to use if you wanted more.
But, missinglettr to the rescue and Ben and his team come out with Post Box and though its not as developed as quuu, i have no doubt it will leave it in the dust. So i became a beta tester and this just gets better. You have the missinglettr platform to post and promote to social, but then what. You need shares, you need engagement and you need POSTBOX. That's the missing piece, don't wait around folks, its the missing part of your online plan. Now go execute like a super sumoling!!!!
