POi BO.. review for AfterShip Email Marketing,SMS

I've been using this app for a few months and love it. The support is very helpful. The only thing, I was offered an unlimited free plan which I've recently found was not forever (which I was never told), and I now have to upgrade to a paid plan to continue using the app. I've been offered a discount, which I value, but I would have appreciated to know from the beginning that the free plan was a limited offer.
