I've been using this software for a few months now for my small business's WhatsApp marketing efforts. It's definitely helped me reach a wider audience than I could manage manually. The data import is straightforward, though I did have a minor hiccup with one CSV file that required some manual cleaning. The scheduling feature is a real time saver. However, the open and response rates aren't as high as I'd hoped, and I suspect that's more to do with the nature of WhatsApp marketing itself than the tool's shortcomings. Overall, it's a valuable addition to my marketing arsenal, simplifying a previously tedious process and allowing me to focus on other aspects of my business. It's not perfect, but it's definitely effective.
