Riftgate review for Loox ‑ Product Reviews App

Signed up for a $40/month plan. Find out they changed their plan structure and have been charging us $120 a month WITHOUT NOTICE. How is this allowed? UPDATE I see the response below and I just want to address some things: I now understand that it wasn't a plan change, but my misunderstanding of the fee structure and "usage charges". I wrongly assumed that for $40/month we'd get more than 300 emails, considering other services provide thousands of email sends for the same price. The plan in question has now been updated to be based on orders instead email sends, a change that feels even less user friendly than before. As for the assertion that said structure is built to "provide great return on investment", clearly we disagree as I wouldn't have left this review if I felt that $120/month was justified for the service we were getting.
