up an automation to do x when a user clicks or doesn't open. I really liked that I could design my newsletters from inside useInbox, but that upgrade on automations seems like a rip off for me. I would definitely be requesting a refund and waiting around for the next email automation software deal here on AS.
Please let me know if your application has this feature. And yes, I second what others have said about the limit being too low.
I also feel like useInbox was extremely stingy with its deal. It is a great app, but they are a little too stingy.
