Targetbay provides great features like A/B testing, product recommendations etc which help in improving conversion rate. The only thing I dislike about this tool is that it doesn't have many integrations with other tools. If you want to use all the functionalities then go ahead otherwise there won't be much point using it as most companies do not provide such features. As mentioned above, we can test our campaigns and see what works best so far. We also get suggestions from target bay's team based on data analysis done.
