The ability to create multiple campaigns from one page is great, it helps us target our audience in so many ways that we never thought possible before! Also having all of your data available at once makes reporting much easier than other platforms out there! I have not found anything yet that isn't fantastic about this platform but if you are looking into an easy way to manage marketing efforts with ease then opti collect will be perfect for you! They've helped me track my ROI better which has been key when trying new products or services.
