Butter & Crust review for OptiMonk: AI Popup Builder

I am using Optimonk for 1 pop-up on my website and paying $99/month for it. Last month Optimonk deleted my one and only pop-up out of the blue due to an error on their side. This resulted in a significant headache and loss of sales for my business (the pop-up is functionally very important to our user journey). Use at your own risk. Even though Optimonk's error led to a significant loss of sales for my business they wouldn't even comp my next month of Optimonk app charges. Poor.
